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 output power measured in step 6 meets the limits in the following table.

>15.5
8.
Repeat steps 4 through 7 for all test frequencies you created in step 3.
9.
Close the external calibration session.
Optional Verification
Use the following procedures to verify nonwarranted specifications for the PXIe-5654.
Verifying RF OUT Amplitude Accuracy
This procedure verifies that the internal signal generation circuitry is adjusted for correct
amplitude accuracy.
1.
Connect the power sensor to the PXIe-5654 RF OUT front panel connector as shown in
the following figure.
