Hi all,
I have in my hands a very nice device called "VNA Master" from Anritsu, model
MS2025B.
The thing is I am trying to measure a Common Mode choke with this VNA, using
S21 mode on the braid of a coax cable with different toroid combinations, but
my knowledge is limited and I am not sure if this device is able to show the
common mode on screen (I think is called "complex impedance").
The options available for the trace are:
Log Mag
Phase
Real
Imaginary
Log Mag/2
Log Polar
Real Impedance
Imaginary Impedance
(Plus some more; SWR, Group delay, Linear Polar, Smith Chart, etc.)
Is any of the above types useful to show Common Mode Choke on screen?
Then , the Marker has some more options to show additional information.
Apart from above list, there are some extra options:
Impedance (Z)
Admittance (Y)
Normalized Impedance (NZ)
Normalized Admittance (NY)
Polar Impedance (PZ)
So, I am not sure if any of those options are good to shown the "choke
impedance" on screen, without additional calculations.
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.
Thank you very much.
Happy New year.
73, Maximo
