Hello,
I have some control board equipped with a microcontroller.
This control board is supplied by 24V laboratory voltage source. I
would like to measure signals on some microcontroller's
output pin with a digital oscilloscope. I have only two common
probes with earthed alligator jack connector. I am not sure
whether the measurement with a probe connected to the output
pin and alligator jack connector connected to minus pole of the
voltage source is correct. Would be better to use both probes
with their alligator jacks connected together and then connect
the first probe on the microcontroller's output pin, the second
probe to the minus pole of the voltage source and use ChA-ChB
function? Thanks.
