Hi,
I have a double balun front end to an ADC that I am trying to characterize for Phase Unbalance. I am using the PNA N5230C. I already have done the cal on the machine. But I am having some trouble doing the data processing on it to arrive at the phase unbalance results. The input is at port1, the output positive at port3 and output negative at port4. I would appreciate it if somebody could give me instructions on how to calculate the phase unbalance.

Thanks
Umesh
