Square Wave Adjustment:
a.
Referring to Fig. 9, connect output BNC to the oscilloscope which has good grounding.
b.
Set the output of the function generator to 20Vp-p, 10kHz square-wave.
c.
Connect the red input line to a 20Vp-p, 10 kHz square wave signal lead and the black input line to
ground lead.
d.
Put SW1 at attenuation 1/10.
e.
Set the VOLTS/DIV switch on oscilloscope’s panel to 0.1V at attenuation 1/10 and the TIME/DIV
switch to 200 us.
f.
Adjust VC1 to make the displayed waveform become as Fig 10(b).
g.
Connect the black input line to 20 Vp-p, 10 kHz square wave signal lead and the red input line to
ground lead.
h.
Adjust VC2 to make the displayed waveform become as Fig. 10(b).
