Verifying RF OUT Phase Noise
This procedure verifies that the internal frequency generation circuitry is adjusted for correct
phase noise 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.
