Signal and Pulse

Width Test

Performance Verification

Verifying the Multiple Channel Controller

The following test will determine if the MEAS BUSY port output pulse width is correct. It will also test the EVENT TRIG input.

1.Connect a BNC cable between the SRC1 TRIG and EVENT TRIG connectors.

2.Connect a BNC cable between the MEAS BUSY connector and the oscilloscope channel 1.

3.On the oscilloscope press:

[TIME BASE] {10 us/Div} [CLEAR DISPLAY]

4. Press the following on the multiple channel controller:

[Clear Instr] [Select Instr] {85330A} [More] {TEST} {EVENT} [1] [Return]

5.While the measurement is cycling, observe the MEAS BUSY pulse on the oscilloscope. The pulse width should be approximately 50 microseconds.

6.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
