trigger consecutive pulses

Post by HerrKrabba »

Hi

In a project I'm working with, I want to use a picoscope (4824A) to compare multiple consecutive pulses.

For instance. The pulse sequence is: _____--_____--_____--_____--_____ ...
I would like to capture this: _--_--_--_--_
I want to use the picoscope to retrieve data for x pulses. but I dont want all the 00 in between the pulses.

I tried using block mode which worked out fine for 1 pulse. But I couldnt figure out how to "reset" the trigger and skip all the data in between.
I tried using streaming mode too, but ran into the same issue.

How should I tackle this problem? I dont want to miss any pulses in between my captures.


Thanks in advance.

What is the time between the pulses ?

Do you want to use the SDK or the picoscope software ?

So you only want the data from when the pulse signal is high ?

Hi
Yes, I want the data for when the pulse is high +- a few samples.
The time in between the pulses are long 0.5s and the pulse itself is very short 1µs.

I want to use the picoscope SDK software.

So streaming is no option because the pulse is 1uS is 1 sample at 1MS/sec and streaming you can get at most 5-10 MS/sec.
How many samples do you want of the 1uS pulse and what is the variation in the 1 uS pulse width.

What programming language do you use ?

can you post a .psdata file from the picoscope software.
you can also use triggers from the picoscope software.
