Adquire one (or a fixed number) of samples after trigger event

[gcorthey]

I need to adquire one sample or a fixed number of samples (say 10-100) after each trigger event and save to buffer.

For example, I have a trigger running at 1 KHz connected to channel 2. I start acquisition and I need to register 50 samples after each trigger event for 100 events and then read the buffer.

How can I do that using scpi commands?

Theoretically, you can capture in a cycle, but SCPI is not the fastest tool. So you can simply not have time to capture and miss the tigers

Hello @b-swat thanks for your answer. Unfortunatelly I don't undersand you suggestion. Could you please expand it more?

Run data capture in a loop. As in this example:

If the speed is not enough, then write an application in C++ or Python on the board itself.
Like here:
