Before you can perform an analyzer calibration, the system hardware connections need to be reconfigured to replace the source hardware with a U9391 Comb Generator as shown in the following diagram:
Because of the USB cable that's required between the PC and the U9391 comb generator, the analyzer calibration configuration cannot be controlled by a remote PC.
The U9391 comb generator has a very high energy output. Be careful to only connect it to the analyzer's RF input. Accidental connection to a signal generator's RF output can cause serious damage to hardware.
