1.Connect a cable from the SYNC OUT connector to the TRIG input of an
oscilloscope. Connect the IN port of the output module to the OUT port on the rear
panel of the mainframe using the supplied coaxial cable. Attach the laser diode
anode to the output module “OUT” terminal. Connect a Tektronix CT2 or Pearson
2878 current probe (or equivalent) as shown below. Connect the current probe to the
oscilloscope. (Some current probes may require a 50 Ohm termination). Set the
oscilloscope to trigger externally.
2.Turn on the AVO-6HF-B. The main menu will appear on the LCD.
3.To set the AVO-6HF-B to trigger from the internal clock at a PRF of 1 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 1 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.
4.To set the delay to 1 us:
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 1 us.
