. When setting the Wavetek to output 10 V, use the following procedure:
Press the
Aux
button
Press the fourth soft key down (Selects the pulse with an exclamation point)
Set the amplitude to 10 V
Press the
- >|
key to select the pulse energy
Set the energy to 50J
Press the Output
On
key
Press the
Trig Pulse
soft key to trigger the pulse (this will generate a 10 V pulse
with 25 seconds duration).
Use the normal DC output for the 1 V, 3 V, and 5 V generator settings.
Turn on the measurement called

e.
Check an unchecked generator setting against limits:
H
Remove the 10X attenuator.
H
Connect the generator signal directly to the oscilloscope.
H
CHECK that the coupling readout on screen for the selected channel
is as listed for the current vertical scale and position/offset/generator
settings.
H
Reinstall the 10X attenuator.
f. Check the next generator setting: Repeat substeps d and e, using the new
generator setting as is listed in the table.
g. Check the remaining vertical scale settings: Repeat substeps c through f
