I have a Rigol DS1054Z, and I'm trying to view two waveforms on two different channels using the "SINGLE" button. Ideally, I want to capture the output from an IR transistor when I click the power button on my remote control, then capture the output from the same IR receiver when I output a signal from my microcontroller attached to an IR LED. I just want to make sure they are outputting the same signal. Is there a way to do this on my scope? Every time I get the first waveform on the screen, and I switch from channel 1 to channel 2 and press the "SINGLE" button, the capture I did on channel 1 disappears.
