Software
1 Prompt the user to make the following connections.
a BNC cable labeled "DUT Gated" to the Trigger Gate (TTL) connector on the back of the DUT.
b RF cable labeled "DUT Channel 2" to the channel 2 input of the DUT (83483A).
c RF cable labeled "DUT Front Trigger" to the front panel trigger input of the DUT.
2 Set the 83712B to 2.5 GHz at -1.51 dBm.
3 Set the DUT to the following.
a Default Setup.
b Trigger on the Front Panel.
c Channel 2 is on and all others are off.
d On 86100C instruments, the Trigger Bandwidth is set to DC–3.2 GHz. On 86100A/B instru-
4 Set the RF and BNC switching for the following.
a BNC short to Open.
b 83712B RF output to DUT channel 2 Input.
c 83712B RF output to DUT Front Panel Trigger.
5 Query to see if the DUT is triggering.
6 Set the BNC switching so that the BNC short connects to the DUT Gated Trigger.
7 Set DUT to enable Gated Trigger mode.
8 Query to see if the DUT is triggering (it should not trigger).
9 Set the BNC switching so that the BNC short is Open.
10 Query to see if the DUT is triggering.
11 If the DUT is triggering for steps 5 and 9 while not triggering for step 7 then the test is a pass.
Otherwise the test is a failure.
