1. Press the following on the multiple channel controller:

[Clear Instr] [Select Instr] {85330A}

2.Connect a BNC cable between the RCVR READY and RCVR TRIG connectors. Press:

[More] {TEST} {RCVR} [1] [0] [0] [Return]

If the test is successful, the RCVR menu will appear on the display. If the test fails, the following error message will appear:

-214, Trigger deadlock

3.Connect a BNC cable between the SRC1 READY and SRC1 TRIG connectors. Press:

{SRC_1} [1] [0] [0] [Return]

If the test is successful, the RCVR menu will appear on the display. If the test fails, the following error message will appear:

-214, Trigger deadlock

4.Connect a BNC cable between the SRC2 READY and SRC2 TRIG connectors. Press:

{SRC_2} [1] [0] [0] [Return]

If the test is successful, the RCVR menu will appear on the display. If the test fails, the following error message will appear:
