Half voltage shown by analog oscilloscope using CH1 and inverted CH2
« on: April 03, 2017, 12:54:21 am »
Why when I use my probe with its own ground cable my analog oscilloscope shows the right voltage, instead when I use CH1 probe with inverted CH2 probe my analog oscilloscope shows half voltage value?

Both channels set to same V / cm ?


If you feed a square wave into both channels, one inverted, you will get 2X
resulting waveform. Both probes same attenuation, 1X or 10X.
