Verifying RF OUT Frequency Accuracy
This procedure verifies that the internal signal generation circuitry is adjusted for correct
frequency accuracy.
1.
Connect the PXIe-5654 RF OUT front panel connector to the signal source analyzer RF
input connector using the K(m)-to-K(m) cable as shown in the following figure.

2.
Create a new device session for the PXIe-5654.
3.
Create a list of test frequencies, including endpoints, containing 100 MHz and 1 GHz,
according to the frequency range of your PXIe-5654 model, with 1 GHz increments.
