Multiple channel and fast digitizing system suggestions

(1/2) > >>

pFtr34wESD:
I am looking for a system to digitize analog signals which are pulses with amplitude from 0 V up to 1 V, rise time 200-600 ps, peak duration from 1-3 ns and noise rms 0.5-2 mV. Currently I am using a LeCroy WaveRunner 9254M and it works very well, but now I need between 12 and 32 channels so I am looking for something else. I don't need an oscilloscope (i.e. no need for a screen, knobs, processing/measuring functions, etc), just need an acquisition system to digitize these signals in a similar way than the 9254M and get the raw data into a PC.

A rough summary of what I need:
- Number of analog channels >= 12.
- Bandwidth > 2 GHz.
- Sampling rate >= 20 GS/s.
- Input range from 0 to 1 V.
- Vertical resolution ~ 8 bit.
- Time acquisition window ~ 100 ns.

I have found a few products that can do something like this but not many. So if you have suggestions that would be very much welcome.

I'm looking for some "black box" as much as possible "plug and play", don't want to develop my own acquisition system for this.

Welcome to the forum.

This is coming, will do what you need however as yet we don't know when:

I'd look at data acquisition products that can have multiple acquisition modules in a mainframe. I would avoid a solution that consists of seperate boxes. The most difficult part is to get seperate boxes in precise time sync (time sync is a big step above frequency sync!) so you can time correlate the signals. This is not something to be underestimated; it is difficult to achieve even when the sampler modules are sitting in the same mainframe!

The Siglent headless scopes Tautech mentioned have proper synchronization but as he says not available at the moment, unfortunately. Other manufacturers have headless scopes too..
Specialized sampler mainframe would be great. I have no firsthand experience with those.

First of all the sampling rate is too low to meet OP's requirements. Secondly it is not a good idea to blindly recommend a product that has not been field tested. Thirdly -as having a lot of experience with synchronising equipment at the single digit picosecond level- I strongly doubt the Siglent solution can achieve time synchronisation at a sufficient level given the block diagram.
