Maximo,
I don't think that instrument will allow you to see the Zcm of a choke
directly on-screen.
However, it looks like it will display |S21| directly. With the choke
connected between the two ports, |S21| will give you a good indication
of |Zcm| for the high values we are mostly interested in [e.g.
|S21|=-40dB implies |Zcm|=10,000Ohms]. The |S21| scan will also allow
you to quickly see the resonant frequency of the choke.
What you wont see easily is the Q of the choke, unless the instrument
can also display the phase of S21.

What I can do, and in fact I do, is to export the measure in .s2p Touchstone
format, then apply some maths on a excel sheet to convert LogMag and Phase to
complex R, complex I, and finally complex Z. All of that on Excel.
But to get that directly on screen would be much better.
