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 read 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.
For the first test, the output module is not used.
1.Connect a cable from the SYNC OUT connector to the TRIG input of an
oscilloscope. Connect a 2.5W (or higher) 50Ω load to the OUT connector on the rear
panel of the mainframe and place the scope probe across this load. Set the
oscilloscope to trigger externally.
2.Turn on the AVO-6A1-B. The main menu will appear on the LCD.
3.To set the AVO-6A1-B to trigger from the internal clock at a PRF of 10 kHz:
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 kHz.
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.
