High Speed Digitizers

Ndigo5G-10 Digitizer Two high speed digitizer products are available from cronologic.

The 5 Gsps 10 bit Ndigo5G is designed for pulse processing applications just as LIDAR and TOF mass spectrometers. Its high PCIe throughput and on board pulse extraction greatly reduce CPU overhead in these applications.

The 250 Msps 14 bit Ndigo250M is a conventional transient recorder that can stream two channels at full sample rate to main memory for virtually infinite acquisition times. Pulse extraction is also available.

The 125 Msps 14 bit Ndigo125M is the slower version of the Ndigo250M. It can stream four channels at full sample rate to main memory.

All three digitizers have an additional TDC channels for triggering. A synchronized system can use a mix of up to eight boards of either type plus up to three HPTDC8-PCI.

Additional Features

  • hardware pulse extraction
  • on board storage for calibration data
  • easy to use Windows C API
  • in system firmware update
