Loic VINET Posted November 6, 2023 Share Posted November 6, 2023 Hello, I am using a python program in a raspberry connected to a digital Discovery. I generate a trigger every 1 second with a duration of 100 ms. When I visualise the trigger, I always see a peak at the beginning of the plot just before the peak of the trigger. When I am using a trigger at higher frequency with a smaller peak, the peak disappears. Why do I have this phenomena with the PPS? Link to comment Share on other sites More sharing options...

0 attila Posted November 9, 2023 Share Posted November 9, 2023 Hi @Loic VINET You are not using the capture properly. You stop after capturing 99% of intended samples, but you should collect until done state is reached. As mentioned in an earlier reply, try using the much easier to use the 'single' acquisition mode.

Question
Loic VINET
Hello,
I am using a python program in a raspberry connected to a digital Discovery.
I generate a trigger every 1 second with a duration of 100 ms.
When I visualise the trigger, I always see a peak at the beginning of the plot just before the peak of the trigger.
When I am using a trigger at higher frequency with a smaller peak, the peak disappears.
Why do I have this phenomena with the PPS?
