I have this problem: when I set a channel in AC coupling with the function PS3000_Set_channel an then (after some minutes) I run acquisition with Block mode with trigger (single pulse), the first acquisition (of 25msec) result in DC. At the second acquisition the data result in AC mode (the capacitor discharge) an the other so on.
I need to read in AC then first trigger too!
How I can? I prefer don't run an acquisition without trigger (the event is not repetitive) for discharge the capacitor.
