MAIN
OUTPUT
Connect an oscilloscope to output.
Observe a 20Vp-p 20KHz (approx.) triangle wave.
FUNCTION
SWITCH
Select and observe a
20V
p-p square wave and sine wave.
AMPLITUDE
CONTROL
Rotate the AMPLITUDE vernier from maximum to minimum and
observe greater than
23dB
of attenuation.
ATTENUATION
Connect the oscilloscope to the OUTPUT and push the
ATT
pushbutton switch that the signal
is
attenuated
by
a factor of
2
0dB.
DC
OFFSET
Reconnect the oscilloscope to the
OUTPUT
and select the triangle
waveform. Rotate the
DC
OFFSET control potentiometer (pull position)
and observe the peaks of the triangle waveform
will
"clip" when the
DC
OFFSET plus the peak amplitude exceeds
Z10V.
Reduce the output amplitude and observe the amount of
DC
OFFSET
may be increased by the same amount the peak amplitude has been
decreased.
Return the potentiometer to "PUSH" position and the
AMPLITUDE
to
maximum.
