3
Set the TIME/DIV switch to the X-Y mode.
4
Set the deviation sensitivity (VOLTS/DIV) of CH1 and CH2 to 0.5 V/DIV.
5
Set the input coupling switches of CH1 and CH2 of the oscilloscope to GND, and adjust the position of
the oscilloscope so that the signal is at the screen center for output format A and the signal is at the
bottom left for output format F, G, and H.
6
Set the input coupling switches of CH1 and CH2 of the oscilloscope to DC.
