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.
