1 Introduction

The Ndigo250M and Ndigo125M are digitizer and transient recorders designed to sample rela-

tively shorts pulses in rapid repetition. They produce a stream of output packets, each containing

data from a single trigger event together with a timestamp.

1.1 Features

14 bit dynamic range

up to 250 Msps sample rate

4 channels

digital input with TDC that can also be used for gating and triggering

digital input for gating or triggering

PCIe x8 Gen 1 with 1400 MB/s throughput

multiple boards can be synchronized

The Ndigo125M and Ndigo250M are almost identical. The only diﬀerence is the use of a

slower ADC in the Ndigo125M. If not otherwise noted this user guide refers to both boards

when using the term ‘Ndigo250M’ or ‘Ndigo250M-14’. These boards are conceptionally very

similar to the Ndigo5G-10 and use an almost identical API. All three types of boards can be

mixed and synchronized by using the cronotools software library. The Ndigo5G-10 merges all

data channels into a single ring buﬀer whereas the Ndigo250M has a separate buﬀer for each

channel.
