d) Press CHANGE to return to the main menu.
8. To change the output amplitude:
a) Press the MOVE button until the arrow pointer is pointing at the amplitude
menu item.
b) Press the CHANGE button. The amplitude submenu will appear. Rotate the
ADJUST knob until the amplitude is set at +100V (or - 100V for "-N" models).
c) Observe the oscilloscope. You should see 100 ns wide, 100V pulses. If you do
not, you may need to adjust the delay setting to a value more compatible with
your sampling oscilloscope. Repeat step 4 if required. You may also need to
adjust the sampling scope controls.
d) Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should
vary. Return it to 100V.
e) ("-PN" units only) Press the +/- button on the front panel. The amplitude as
seen on the oscilloscope should flip polarity, to -100V.
f)
Press CHANGE to return to the main menu.
9. Try varying the pulse width, by repeating step (5). As you rotate the ADJUST knob,
the pulse width on the oscilloscope will change. It should agree with the displayed
value.
This completes the operational check.
