Measuring Choking Impedance

Hi
Can I measure choking impedance of a choke balun using this? If so how?
Appreciate your help on this.

Cheers

i measure attenuation between port 0 and port 1 and connect the baluns
shield to the two ports hot wire (inner conductor)

you wanna measure how much choking the balun has so you have to connect
the 2 ports to the two spots between you wanna see the "attenuation" ...
means connect both shields (balun in and out) to both hot wires of the
analyzer ...

you should measure a high attenuation between the 2 ports (the choking
impedance represents a high resistance)

hope that helps
