Image of Ndigo125M-14 digitizer The Ndigo125M-14 is a high resolution digitizer board. Compared to the Ndigo5G it provides a higher vertical resolution of 14 bits at a reduced sample rate of 125 Msps.

On the fly thresholding and zero suppression allows for a dramatic data reduction and reduced CPU load for pulse processing applications like LIDAR, TOF spectrometers, PET scanners or other applications based on time of flight measurement.

Even without data reduction the 8 lane PCIe bus master interface provides enough bandwidth to stream four channels continously into main memory.

The Ndigo250M-14 is an alternative with higher performance, i.e. 250 Msps sample rate.
