I have a borrowed 3205 I am evaluating to recommend for use in a sonar application. I have a TTL trigger when my transmitter fires and I want to examine an echo that occurs 300us later and lasts about 10us.
The problem is that the TTL trigger is noisy. I want to trigger on the "main" rising edge but the Picoscope is as likely to trigger on a bounce of the falling edge which is many ms later meaning about half the scans are mis-timed resulting in an annoying display flicker. On my old Tek bench scope I have several levels of filtering I can apply to the trigger which easily solve this problem, but I don't see any way to do that on the Picoscope. Adjusting the trigger level doesn't help. Is there something I am missing?
Which product is right for your exact requirements
