c) Observe the oscilloscope. You should see 500 ns wide, +20V pulses. If you do
not, you may need to adjust the delay setting to a value more compatible with
your sampling oscilloscope. Repeat step 5 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 +20V.
e) Press the +/- button on the front panel. The amplitude as seen on the
oscilloscope should flip polarity, to -20V.
f)
Press CHANGE to return to the main menu.
9. Try varying the pulse width, by repeating step (6). As you rotate the ADJUST knob,
the pulse width on the oscilloscope will change. It should agree with the displayed
value.
10. To set the AVR-D2-B to generate the Channel 2 waveform on the output connector:
a) Press the MOVE button until the arrow pointer is pointing at the “Route” menu
item.
b) Press the CHANGE button. The active channel submenu will appear.
c) Rotate the ADJUST knob until “2” is the actice channel.
d) Press CHANGE to return to the main menu.
e) Observe the oscilloscope. You should see 15 ns wide, -2V pulses. If you do
not, you may need to adjust the delay setting to a value more compatible with
your sampling oscilloscope. Repeat step 5 if required. You may also need to
adjust the sampling scope controls.
This completes the operational check.
