Installation

The phase calibration procedure is carried out by following the 
on- screen instructions on the PNA- X. 

After completing the calibration, the U9391C/F unit used for 
phase calibration can be disconnected. The other unit that is 
used as the phase reference will remain connected while the 
measurement is carried out.

For more detailed information, please refer to the Help file that 
is embedded in the NVNA application.

C A U T I O N

When connecting the U9391C/F directly to the instrument test ports, 
the modules will require mechanical support so as not to overstress 
the test port connectors.
