Coarse and Fine Gain Controls
1.
Set the 2015A COARSE GAIN to 128; FINE GAIN to 10.0.
2.
Connect the AMP OUTPUT to the scope with RG-62 coax cable.
3.
Set the 1407 ATTENUATION to X500. Adjust the Model 1407 PULSE
HEIGHT until the AMP OUTPUT pulse attains an amplitude of +9.9 to
+10.1 volts.
4.
Measure the AMP OUTPUT on the scope for each COARSE GAIN setting.
The amplitudes should, reduce proportionately with each COARSE GAIN
setting.
5.
Set the 2015A CORSE GAIN to 128.
6.
Monitor the AMP OUTPUT on the scope and turn the 2015A FINE GAIN
control to minimum. The signal amplitude should decrease by approximately
2/3.
7.
Return the FINE GAIN to maximum.
Shaping Checks
1.
Set the 2015A to 2
µ
s shaping.
2.
Set the 1407 ATTENUATION to X500. Adjust the 1407 PULSE HEIGHT
until the AMP OUTPUT pulse attains an amplitude of +9.9 to +10.1 volts.
3.
Observe the AMP OUTPUT pulse on the scope. For each of the shapings
(2.0
µ
s and 0.5
µ
s), the unipolar pulse should appear as in Figure 19.
