output of the niRFSG
5654 OCXO Cal Adjust VI returns a value of TRUE.
9.
Call the niRFSG Close External Calibration VI to close the session. Set the

parameter to TRUE to store the results to the EEPROM on the
PXIe-5654.
Adjusting RF OUT Power
This procedure adjusts the PXIe-5654 RF OUT power using a power meter. This adjustment
yields a more accurate output power for the PXIe-5654 RF OUT front panel connectors.
1.
Connect the power sensor to the PXIe-5654 RF OUT front panel connector as shown in
the following figure.
