Can Picoscope save high-frequency data?

Post by mars »

I have sent and received pulses between a pair of transducers setup on the Picoscope. The pulses are sent 20 times a second and what I would like to do is save the sent and received pulses I see on the software screen. I have tried using an Alarm to save each buffer but that only updates once or twice a second despite the file size only being 18kB. Is it possible for the Picoscope software to save the two channels @ 20Hz or is this only possible using the SDK? I would like the channels to be triggered then both traces saved.

Hi,
The best way of doing this is to use "Streaming" mode to capture a large number of samples on screen and then "Zoom" in to view the details.
You do not say how long you wish to record or at what sample rate but a a start try:-
First set up the "Requested number of samples":- 100MS
then
Collection Time:- 1 s/div
This will give you a 10 second capture at about 10 MS/sec.

You can also have a longer capture:-
Collection Time:- 10 s/div
This will give you a 100 second capture at about 1 MS/sec.

or even:-
Collection Time:- 100 s/div
This will give you a 16 mins 40 second capture at about 100 kS/sec.

Use the "Zoom" functions to view the individual pulses in detail, there will be a lot of them!

Regards,
PeterF.
