Solution
Photonics and Time-Resolved Measurement
Fast, deep capture for laboratories where sample rate and record length matter more than channel count.
Time-resolved optical measurement, LiDAR development and quantum optics work all share a shape: a small number of very fast channels, a trigger that has to be exact, and a record long enough to catch an event that will not repeat on command.
The high-rate end of the converter catalog is built for that, and every module takes an external clock and external trigger so the digitizer can be slaved to the experiment rather than the other way around.

Where to start
Products for this application
The fastest module in the catalog: 6.4 GSPS single-channel, 14-bit.
Two coherent channels at 2.6 or 3 GSPS when the measurement is differential.
Waveform generation at 12 GSPS for pulse shaping and arbitrary excitation.
When the experiment already lives in a rack: 3U VPX with 32 GTH lanes to the module.
Before you specify
Questions worth settling early
- How long a record can we hold?
- Carriers carry 2 GB to 4 GB of DDR as a capture buffer, which at 6.4 GSPS and 14 bits is on the order of a hundred milliseconds. Past that the question becomes a recorder question rather than a converter question.
- Can we trigger from the experiment?
- Yes - external trigger on every converter module, plus external reference clock, IRIG-B and PPS inputs on the carriers.
- We need something that is not in the catalog.
- Common in this field, and usually a converter-and-front-end change on an existing carrier rather than a new design. Describe the measurement and we will tell you honestly whether it is a variant or a program.
