I have dso nano V3 with version V4_22 firmware. I can’t figure out how to trigger a single scan and have it stay on the screen. I have a 4 volt signal that will eventually go low to almost 0. I want to capture the signal after the first high to low transition, scan samples in at the current sample rate and then stop. Is that possible?
So far I hae not been able to figure out how to do that. I can get it to trigger and display the signal in auto mode but then it is erased from the display in less than a second as the device scans once more. I can not press the stop button (B?) fast enough to keep it from updating the display with the next
