OPERATIONAL CHECK
This section describes a sequence to confirm the basic operation of the instrument. It
should be performed after receiving the instrument. It is a useful learning exercise as
well.
Before proceeding with this procedure, finish reading this instruction manual
thoroughly. Then read the “Local Control” section of the “Programming Manual for -B
Instruments” thoroughly. The “Local Control” section describes the front panel controls
used in this operational check - in particular, the MOVE, CHANGE, and ADJUST
controls.
1. Connect the pulser, the load, and the oscilloscope as described in the preceding
“Basic Test Arrangement” section on page 42. Install a daughterboard (with no
DUT) in the socketing.
Confirm that the scope probe, test load, cables, and any adapters used are
rated for 2 kV pulsed operation.
2. Turn on the AVRQ-4-B. The main menu will appear on the LCD.
3. To set the AVRQ-4-B to trigger from the internal clock at a PRF of 10 Hz:
a) The arrow pointer should be pointing at the frequency menu item. If it is not,
press the MOVE button until it is.
b) Press the CHANGE button. The frequency submenu will appear. Rotate the
ADJUST knob until the frequency is set at 10 Hz.
c) The arrow pointer should be pointing at the “Internal” choice. If it is not, press
MOVE until it is.
d) Press CHANGE to return to the main menu.
4. To set the delay to 50 ns:
a) Press the MOVE button until the arrow pointer is pointing at the delay menu
item.
b) Press the CHANGE button. The delay submenu will appear. Rotate the
ADJUST knob until the delay is set at 50 ns.
