Keeping the connection ON and triggering acquisition

Post by simonbl » Tue Jun 04, 2019 3:03 pm

Hi,

I am not sure how to do that but I would like to keep the connection activated with the picoscope but to start an acquisition of data ( like 2 seconds) with a trigger.
I need a robot arm to move around an hydrophone and read that value at different locations. So I would use a loop, that would trigger the acquisition, and save the data.

Thanks for the help,
Simon

Hi Simon,

Could you tell me why you want to keep the connection activated, whether you want to do this in PicoScope 6 or in the SDK API, and what your required sample rate and PicoScope Model are?

Assuming that the reason for your question is that you're concerned about missing a trigger, then if your sample rate is not too fast, and you're using the SDK, then you could stream the data and use the trigger as a marker to where you need to start and stop (i.e. 2 seconds later) copying the data to a separate buffer for analysis.

Regards,
