Output Trigger Test

The following test will determine if the rear-panel ports output the correct signals. Note that a single press on the specific {TRIGGER} key will cause a single trigger pulse. If you hold down this key, a train of trigger pulses will be outputted.

1.Connect a BNC cable between Channel 1 of the oscilloscope and the multiple channel controller rear panel BNC connector that is being tested.

2.On the oscilloscope, press:

[RECALL] [1]

3.Connect the BNC cable to the RCVR TRIG connector on the multiple channel controller, and press:

{85330A} {TRIGGER} {RCVR}

On the oscilloscope, press [CLEAR DISPLAY]. You should see a negative pulse, with an approximate width of one to three microseconds.

4.Connect the BNC cable to the SRC 1 TRIG connector on the multiple channel controller, and press:

{SRC_1}
