Die Entwicklung des Zeitbereichsmessung

Die Messtechnik in der Time-Domain hat in den letzten Jahren erhebliche Fortschritte gemacht, insbesondere bei der Entwicklung neuer Analog-Digital-Wandler (ADCs) und Zeit-Digital-Wandler (TDCs). Die präzise Erfassung von Zeitinformationen ist in einer Vielzahl von Anwendungen von entscheidender Bedeutung, sei es in der medizinischen Bildgebung, bei der Laserentfernungsmessung oder bei der Hochfrequenzsignalanalyse. Als Teil der neuen TimeTagger Generation hat cronologic besonders platzsparende TDC-Module entwickelt, die über ein kundenspezifisches analoges Frontend integriert werden können. Als Alternative zur üblichen Differenzzeitmessung können unsere TDC-Module auch im "Continous Mode" arbeiten, sodass Stoppsignale kontinuierlich aufgezeichnet werden, auch wenn kein Startsignal eingespeist wird.

Die Zeitinformationen der steigenden bzw. fallenden Flanken digitaler Impulse werden von den TimeTagger-TDC-Modulen mit der folgenden Quantisierung aufgezeichnet (Bin-Sizes):

‍

• TimeTagger4-1.25G-Modul: 800 ps

• TimeTagger4-2.5G-Modul: 400 ps

• TimeTagger4-5G Modul: 200 ps

• TimeTagger4-10G-Modul: 100 ps

Profitieren Sie von den Vorteilen der Modularität!

Mit ihrer Größe sind die TDC-Module von cronologic extrem kompakt und nehmen nur einen Bruchteil des Platzes unserer PCIe-Boards ein. Dies ermöglicht die Integration in kleine, leistungsstarke Geräte, ohne deren Leistung einzuschränken. Dank ihres kleinen Formats eröffnen die Module neue Möglichkeiten für die Erfassung präziser Zeitinformationen in verschiedenen Bereichen der Forschung und Entwicklung.

Trotz ihrer geringen Größe bieten die TDC-Module von cronologic eine außergewöhnliche Zeitauflösung und Genauigkeit. Sie können extrem kurze Zeitintervalle präzise messen, was für viele anspruchsvolle Messanwendungen von entscheidender Bedeutung ist. Diese kleinen Module sind besonders vorteilhaft, wenn Kosteneinsparungen bei der Integration im Vordergrund stehen. Die Verwendung modularer Schaltungen kann Ihre Entwicklungskosten senken, da Sie einsatzfähige, bewährte Module verwenden können, anstatt komplexe Schaltungen von Grund auf neu zu entwickeln.

Die Integration von TDC-Modulen in bestehende Systeme erfolgt über ein kundenspezifisches analoges Frontend. Dies spart Ihnen Zeit bei der Entwicklung und ermöglicht es Ihnen mit Neuentwicklungen schneller auf den Markt zu kommen, wobei Sie dennoch die Geräte Ihren individuellen Forschungs- oder Anwendungsanforderungen anpassen können.
Dies ist insbesondere dann von Vorteil, wenn sich Ihre Anforderungen und Technologien an die Zeitbereichsmessung ständig weiterentwickeln. Unsere TDC-Module werden über Platinen-Steckverbinder mit Ihrer Messplatine verbunden, wobei in Ihrem analogen Frontend differenzielle Eingangssignale verwendet werden. Wir stellen Ihnen diesbezüglich gerne ausführliche Informationen zur Verfügung.

Eines der herausragenden Merkmale unserer neuen TDC-Module ist ihre Modularität. Es ist möglich, Module mit genau den optimalen Leistungsparametern für verschiedene Anwendungen zu verwenden, auch wenn dafür das selbe analoge Frontend verwendet wird. Darüber hinaus können die Module bei (im unwahrscheinlichen Fall eines Defekts oder bei Upgrades) ggf. einfach ausgetauscht werden, ohne dass das gesamte Messgerät überarbeitet werden muss. Somit sparen Sie Zeit und Geld bei der Wartung und Aktualisierung von Geräten.

Wir bieten unsere TDC-Module in erster Linie Kunden an, die größere Mengen bestellen, um sie in ihre Serienproduktion zu integrieren. Für Preisinformationen kontaktieren Sie uns bitte mit Einzelheiten zu Ihrer aktuellen Einkaufs-Prognose.

Falls in Ihrem Setup ein freier PCIe-Steckplatz verfügbar ist oder Sie eine Verbindung via Thunderbolt bevorzugen, sind sicherlich unsere TimeTagger für Sie von Interesse.

Frequently asked Questions

product choice

I have no idea whatsoever which measuring card is suitable for my application. Can you advise me on this?

We would be happy to assist you in selecting a board for your application.

For this purpose we need the following information:

How many measurement channels are needed?

What is the required time resolution?

Do you want to measure the area, intensity or shape of the pulse? Or is the time of occurrence sufficient?

Do you prefer a PCIe CEM card housed in a PC, or do you prefer an external device connected to a Thunderbolt / USB4 port?

Are you aiming for the most space-efficient data acquisition integration possible?

Regarding your timeframe, are you only interested in products that are available now, or are you also interested in upcoming products or custom solutions?

The best way would be for you to use one of our inquiry forms and fill it out completely.

TTL signals

Are cronologic TDCs able to generate TTL or similar signals to synchronize other devices such as lasers, switches, etc.?

All cronologic TDCs that have the "TiGer function" offer this option. You can find more detailed information on this in our user guide for the corresponding device.

specific connection formats

Are cronologic measurement boards also available with optical inputs, BNC/SMA or SMB connections or with additional converters?

For some of our major customers, we currently offer solutions with SMA connections as part of special developments. Depending on the desired measuring card, it might be quite easy to find such a solution for you as part of a custom design.

We can also implement other connection formats as part of custom designs for larger product volumes.

However, suitable adapter cables may also be available on the market.

Please let us know your exact requirements and the intended quantities so that we can take care of the matter.

PC configuration

Is there a recommended PC configuration for use with these measuring boards?

As virtually all reasonably up-to-date PCs will run with our measurement cards, we do not provide any explicit details in this regard. Writing the memory contents to your PC does not require particularly high performance. Rather, the performance requirements of the computer used are determined by the application software used.

size of jitter

What size is the jitter of the cronologic TDCs?

Jitter refers to the deviation in the time it takes for data to arrive at each time window. It is often assumed that the jitter is at the FWMH value of 2 bins. This is not the case with our TDCs, as here jitter is not the limiting factor. Double-pulse resolution, on the other hand, is an important specification for most applications and is the limiting factor in terms of resolution. However, this is not directly related to the jitter of our measurement cards, as the jitter of our TDCs is significantly smaller than the bin size. Accordingly, the RMS error is so small that we do not consider it to be significant.

See also: bin-size, jitter, and RMS

‍

input level

In which level should the signals I use range, which I feed to the inputs of the measuring cards?

Please refer first and foremost to our information in the User Guide for the respective product. The following technical specifications are subject to change without notice.

  • Our standard TDCs are AC coupled. The DC base line can be between 0V and 5V for these devices. Short positive and negative pulses with an amplitude of up to 5V can be processed. The discriminator threshold can be set between -1.32V and 1.18V relative to the DC baseline, with a step size of 40 µV. In general, the threshold voltage should be set well above the noise level of the input signal.
  • The inputs of our standard ADCs are AC-coupled single-ended analog inputs. The maximum input voltage is 0.5 V and the input impedance is 50 Ω. The analog offset can be between -0.25 and +0.25 V.

constant fraction discriminator

Do the cronologic measurement cards offer an integrated CFD (Constant Fraction Discriminator)?

Since our measurement boards are designed for a wide range of applications, we do not integrate CFDs into our standard models. In principle, however, it is of course possible to operate our boards with external CFDs, which is also done by many of our customers. The threshold function (threshold comparator) is in most cases already sufficient to pre-sort the pulses on the input side. This is because the digital threshold is adjustable for each input and can alternatively be configured for positive or negative pulses. Please refer to the operating instructions for more information.

In case extremely high demands are made regarding the comparator, an external device may be used.

‍

TDC integration

How can I integrate cronologic TDCs into my measurement setup in a reasonable way?

In addition to using the PCIe interfaces of our measurement boards, the integration of our TDC modules can be considered for the TimeTaggers. The TDC modules are connected to your board via board-to-board connectors, using differential input signals for your analog front end. We will be happy to provide you with detailed information in this regard.

Alternatively, before purchasing an xTDC4-PCIe respectively TimeTagger, consider supplementing the TDC with our TBT2PCIe enclosure, which allows data transfer via USB4 using conventional Thunderbolt cables.

The xHPTDC8-PCIe is integrated exclusively via its PCIe interface.

bin size, jitter and RMS

How are bin size, jitter and RMS error related?

The bin size, jitter, and RMS measurement error are all important parameters that play a role in the digital acquisition of time data.

  • The bin size refers to the width of the time windows into which the data is divided during the measurement. The smaller the bin size, the higher the temporal resolution of the measurement. However, if the bin size is too large, there may be an overlap of data between each time window, resulting in an inaccurate measurement.
  • Jitter refers to the deviation in the time it takes for data to arrive at each time window. When jitter is high, data in a circuit can be erratic or inconsistent, resulting in an inaccurate measurement. Jitter is not directly related to bin size and therefore cannot be calculated directly from it. Jitter can be considered as the measure of the temporal variability of the acquired signal edges.
  • The RMS measurement error refers to the average deviation between the actual values of the input data and the values generated by the measurement. The lower the RMS measurement error, the more accurate the measurement.

TimeTagger dead time

What has to be considered with regard to the dead time respectively the input frequency for the TimeTaggers?

The term dead time refers to the time lag or time offset that can occur when measuring with a TDC. The dead time specified in technical data of TDCs and the input frequency refer to the same parameter and are directly dependent on each other. An input frequency of 200 MHz, for example, corresponds to a double pulse resolution of 1/5 ns.

The extent to which this value is relevant for your measurement depends on the sensors used. Only in case the dead time of your sensors is extremely small and a high resolution is required, this value will be relevant for you.

The TimeTagger measures start and stop with the same resolution and bandwidth. Thus, starts at the distance of the double pulse resolution are also handled correctly - the dead time thus corresponds to the double pulse resolution in practice.

common start

What is the key feature of a common-start TDC?

Common -Start TDCs, such as our TimeTagger or the xTDC4 provide a list of time stamps relative to a common start signal. This means the timestamps reflect the time difference between the start signal and the pulse measured on another TDC channel. The start signal must temporally precede the pulses being measured.

‍

delay function

What are the capabilities of the delay function of the TimeTagger's input signals?

The user can implement user-defined delays on the measured time stamps in the software of the TimeTaggers. The input signals can be shifted with 200ps resolution in a range of approx. 200ns.

The xTDC4-PCIe features no input delays. However, after the common-start group has been formed by the hardware, your software can implement any delays for the events present in the group.

Continuous Mode

Are cronologic TDCs able to record a continuous data stream over several hours?

Please note:

  • The xHPTDC8-PCIe provides an infinite stream of timestamps - one for each input channel.
  • The current TimeTaggers and TDC modules offer a Continuous Mode, and the measurement is not limited in time. In this mode, the device continuously records stop signals even without a start signal connected. The data stream periodically contains packets with an absolute 64-bit timestamp, followed by a list of stops relative to this timestamp. The period of the timestamps can be customized to fit the used evaluation interval. The config.tdc_mode parameter is used for this purpose, which switches between grouping and continuous. In continuous mode, grouping is only supported insofar that it can be performed by the evaluation software. In this case, the measuring card provides packet timestamps with ascending identifiers so that all packets can be evaluated accordingly.
  • The xTDC4-PCIe, on the other hand, is based on a classic common-start architecture in which the arrival times of pulses at the "stop" inputs are measured relative to a signal at the "start" input. The duration of the recording is therefore limited in time.
  • The TDC channels of the Ndigo6G-12 all work in continuous mode to optimally complement the ADC measurements.

Please also note: The previous generation TimeTaggers (TimeTagger4-1G and TimeTagger4-2G) do not offer Continuous Mode.

multiple TDC channels

How does the use of multiple input channels affect the performance of my card?

The data acquisition of our TDCs is based on PCIe DMA. Thereby the maximum utilization of the data rate will in some cases only be reached if solely one measuring channel is used. In our technical data you will find the readout rate, which describes the maximum value and also the readout rate for the use of individual channels.

You are welcome to explain your application to us in detail, so that we can work out together how you can exploit the performance of our product to the maximum.

pulse width measurement

Do TDCs only provide the arrival time of incoming pulses or also the pulse width?

Since the pulse amplitude is not measured when using TDCs, in many applications a derivation of the pulse intensity from the pulse width comes into question. In these cases, it may be useful to measure the pulse width as well as the arrival time of the pulse. For the acquisition of single photons, however, this is usually not necessary.

The measurement of pulse widths (i.e., a simultaneous measurement of falling and rising pulse edges) is feasible in most cases, but the specifics depend on the type of card in use.

‍

  • The cronologic TimeTaggers are optimally suited for capturing the arrival time in conjunction with the pulse width. They provide (if enabled) timestamps of both the rising and falling edges of the measured pulse. The time difference corresponds to the pulse width.
  • Pulse width measurement is also possible with the xTDC4-PCIe, though it is more involved.
  • The integrated TDCs of the Ndigo5G-10 and the Ndigo6G-12 are also capable of capturing both edges of the pulse.
  • The xHPTDC8-PCIe captures only one edge per pulse, so the pulse width cannot be obtained with this device.

‍

TiGer

What exactly is the function of the TiGer (timing generator)?

To use inputs to output arbitrary periodic pulse patterns for controlling your setup, you can write your own software that allows exact measurement of the timing of these patterns with the TDC. The TiGer can be used to measure exact timing differences between the generated output signals and various input signals on other channels. This is useful for a variety of applications.

The TiGer functionality can be configured independently for each port. Each TiGer may connect its output to the corresponding LEMO port. This turns the port into an output. The TiGer is DC-coupled to the connector. Connected hardware must not pass signals to the ports used as outputs, as this could damage both the TDC and the external hardware.

For this purpose, each digital LEMO-00 input can be used as an AC-coupled trigger output, whereby the TiGer functionality can be configured independently for each connection. This converts the relevant connection into an output. A bidirectional mode allows this output to be used consistently as a measurement channel if required. Unipolar or bipolar pulses may be used.

‍

firmware updates

Is it possible to update the firmware of my cronologic product by myself?

Yes, a corresponding program for updating the firmware is part of the driver package for our cards. Caution: Each firmware update requires a new calibration of the card using the provided calibration software. In some cases, it is necessary to provide appropriate input signals for this purpose.

driver download

Where can I find the appropriate driver for my cronologic product?

On the pages containing product information, there is a corresponding tab. Plus on this website, all downloads for our products are listed. This also applies to products that are no longer in our current range.

For Linux support please use this page.

software integration

With the measurement cards, do you offer software that can display histograms, count rates, coincidences, etc. with controlled time windows such as counts/s or counts/ms?

No. As our customers' requirements for evaluation software are very application-specific, they prefer to program their evaluation software and are happy about the lower hardware costs. Histogramming and other analysis of the timestamps can be programmed by the user with a few lines of code. We provide a C API that can be used to receive a stream of timestamps in almost any programming language.

‍
In case you are active in research, e.g. in the field of atomic physics, we can put you in touch with partner companies that offer our products in a package with software packages.

‍

MATLAB

Is it possible to use the cronologic DAQ boards with MATLAB based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

We do not provide a separate interface to MATLAB. Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format.

Matlab probably offers several ways to use C++ classes. This seems to be a viable way, although it is not trivial.

Another possibility is demonstrated here.

By the way: For basic applications that are rarely called, there is another way to solve the problem as the driver of our measuring cards offers a tool which records the data into a .csv file. This can then be analyzed in MatLab or also Excel. However, the amount of data generated is quite large, so you have to make sure in your own code that the data is really processed in real-time.

golang

Is it possible to use the cronologic DAQ boards with Go based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

We do not provide a separate interface to Go / Golang. Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format.

‍

Julia

Is it possible to use the cronologic DAQ boards with Julia based software?

Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format.

‍

Rust

Is it possible to use the cronologic DAQ boards with Rust based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format. Wolfgang Löffler has created Rust bindings for our drivers. He has published code on GitHub under the Mozilla Public License that shows how to use TimeTagger4 and HPTDC8 with Rust. It should be easy to port this code to the xTDC4 and xHPTDC8 in case.

Linux

How can I use cronologic hardware most efficiently in Linux environment?

‍

Our Linux-Supportweb page provides drivers and support for GNU/Linux based applications. ‍Please provide us with information about your application and the driver requirements for your Linux distribution and kernel version. Please note that only kernel versions from 5.0 (March 2019) are supported.

Python

Is it possible to use the cronologic DAQ boards with Python based software?

‍

We provide a C API that may be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

In principle, the use of Python based software is possible along with wrappers. Our customers write their own wrappers suitable for their particular application. For example, there is a Python wrapper for the HPTDC8.

‍

non-sequential signals

Are cronologic TDCs also able to detect non-sequential or non-synchronized signals (i.e. random or emission signals detected by SPAD and not triggered by pulsed excitation), or can these boards only detect synchronized signals with an external source such as a pulsed laser?

Yes, such signals can also be detected. If this is not desired, the config.tdc_mode parameter can be used to switch between grouped and continuous measurement.

‍

trigger

My product development respectively my experiment requires a trigger that I want to use as a start signal. Which TDC is best for me?

‍

In this case, we recommend one of our Common Start TDCs, such as the xTDC4, TDC modules or one of our TimeTaggers.

infinite stream of timestamps

I want to capture an infinite stream of timestamps instead of time differences related to a common-start signal. How can this be performed?

‍

This function is not supported by the xTDC4-PCIe. Therefore, in this case we recommend using our xHPTDC8-PCIe, which has been optimized for this application. Our TimeTaggers and TDC modules offer a continuous mode, which allows continuous data recording.

defense

The company I work for is also closely associated with suppliers operating in the defense sector, or we produce military products ourselves. Is cronologic willing to supply us?

As part of our own sales policy, we would like to ensure that our products are not used in weapons systems. If you are considering purchasing our ADCs or TDCs, please let us know how you can ensure that the use of our products for military purposes can be reliably excluded.

  • Details of the quantity of the desired cronologic products
  • if necessary, information about the desired delivery date
  • Your complete billing address and delivery address including the telephone number of your head office
  • If your billing address is in the European Union: Your VAT number

shipping insurance

Are the goods covered by insurance when they are shipped ?

‍

We ship fully covered unless you specifically tell us that you have external insurance and therefore would not like us to do so.

shipments

How do we ship your goods?

We ship your goods via FedEx or UPS through your account. Thus you have full control over the shipping costs and can use your own conditions with the shipping company. In case you do not have a FedEx or UPS account, we will ship your order via our own UPS account and show the shipping costs separately on your invoice or within our offer. Please note that this procedure usually leads to significantly higher shipping costs. It is financially more worthwhile for you to open a new FedEx or UPS customer account - especially because you can then take advantage of the new customer offers of these shipping companies.

FCA incoterms

What does shipping to FCA Incoterms mean?

The International Commercial Terms are clauses for the interpretation of commercial contract standards. FCA (Free CArrier) is one of the clauses, which exclude the assumption of the costs for the main transport by the seller. In this case, cronologic takes over the handover to the carrier and, if necessary, also the customs declaration.

delivery restrictions

Are there any restrictions regarding the delivery of measurement cards to certain countries?

Our ADCs are classified as so-called dual-use goods, as they could be used for military purposes in addition to civilian applications. TDCs and Crates are not affected by these restrictions.

Regardless of the fact that we at cronologic want to exclude the use of our products for military purposes, the laws of the EU and many other countries restrict exports. Since we have to apply for a General Export Permit for these countries, delivery processes may be delayed or delivery to certain countries may become impossible.

For the application of this export license we need the following documents from you:

  • Exporter declaration
  • Company profile
  • Gegbf. import license (country dependent)

There are countries for which a general export license can be used for the export of dual-use goods. In this case we need documents from you and there will be no further delay:

These include:

  • Australia
  • Japan
  • Canada
  • Liechtenstein
  • New Zealand
  • Norway
  • Switzerland
  • Singapore
  • USA

goods dispatch

How long does it take to receive my ordered goods?

Provided that the ordered goods are products from our standard portfolio and are in stock, it can usually be assumed that the delivery will be dispatched within 14 days after receipt of the order. During this time, the item is subjected to a further detailed calibration and final inspection, packed and made ready for dispatch. Of course, it is always a requirement that all details regarding customs and shipping have been clarified in advance.

import permit

For which purpose is an import permit required and where can I get it?

Governments may impose certain restrictions on the imported goods as well as on their quantity. As a result, import licenses may be required. Such an import license is a document issued by a national government that allows certain goods to be imported into its territory. This is the international import document IC, which you may need to apply for at your customs office. Each import license specifies the quantity of imports allowed, and the total quantity allowed should not exceed the quota.

You need our export declaration to apply for an import permit.

Please find more information on the WTO website.

reseller

We are resellers and need sufficient margin for our services. Can cronologic help us with this?

As a matter of principle, yes, this is possible. In the run-up to our collaboration with companies that consider themselves resellers, we examine their business model in detail. This will take some time. Please provide us with comprehensive information about your company respectively your corporate group, your customers and the complete scope of your product range.
