6.
Measure the PXIe-5654 RF OUT front panel connector power using the power meter.
Correct the power meter reading for the RF frequency.
7.
Verify that the power output measured in step 6 meets the requirements in the following
table.

8.
Repeat steps 4 through 7 for each test frequency in the list you created in step 3.
9.
Close the external calibration session.
Verifying PULSE IN Operation
This procedure verifies that the PXIe-5654 PULSE IN connection is functioning.
1.
Connect the signal source analyzer RF input to the PXIe-5654 RF OUT front panel
connector using the K(m)-to-K(m) cable.
2.
Connect the Port 0, Line 0 (P0.0) output of the USB digital output device to two separate
connectors using a BNC Tee connector and a BNC(m)-to-terminal block adapter.
a)
Connect the P0.0 output of the USB digital output device to the signal source
analyzer EXT TRIG/GATE IN back panel connector using a BNC(m)-to-BNC(m)
cable. (Not pictured.)
b)
Connect the P0.0 output of the USB digital output device to the PXIe-5654 front
panel PULSE IN connector using BNC(m)-to-SMB(f) cable.
The hardware setup is shown in the following figure.
