Test
The following test determines if the on-board counter is operating correctly.
1. Connect BNC cables between the SRC1 TRIG, RCVR READY
connectors and the oscilloscope as shown in
2. On the oscilloscope press:

[TIMEBASE] {1 us/Div} {Delay: 4 us} {Ref: Centr}
[SAVE] [2]
3. Press the following on the multiple channel controller:
[Clear Instr] [Select Instr] {85330A} {RESET} [More] {TEST} {COUNTER}
4. Press the following on the multiple channel controller:
[4] [Return]
5. The negative edge of the displayed pulse should be 4

Rotate the front panel knob until the vertical marker line intersects the
negative edge of the pulse. Note that the Start Marker reading will be the
pulse delay. See
6. On the oscilloscope press:
