The goal of this adjustment is to determine the conversion loss through the RF and IF hardware paths in a defined hardware state. The defined hardware state is defined by the Downconverter Base Path Setup Adjustment.
The network analyzer used in this adjustment must be calibrated prior to running the adjustment. The calibration will need to be repeated once every three days or if the connectors or cables have been disturbed. If it's been within the three day time frame and the connectors and cables have not been disturbed, then the network analyzer calibration is not necessary and you may proceed with the adjustment.
For a list of required equipment and calibration instructions to perform the network analyzer calibration, go to the Network Analyzer Calibration Procedure topic page.
