Measurement of the absolute value of the complex impedance using scalar detectors

[admin]

Hello friends,

Can somone give me some info about:

Measurement of the absolute value of the complex impedance using
scalar detectors. I mean detectors which can measure
magnitude/power/RMS but not phase
of the sine wave.

Thank you!

Dear Glenn,

Thank you for the replay.

I know about six port reflectometer.

I was wondering is there simpler configuration which is able to
provide me with the magnitude of the complex impedance of the DUT
directly. I was tring to derive it using 2 scalar detectors but without success.
Probably can be done with 3 detectors?

The six port reflectometer uses 4 scalar detectors and we got the complex
impedance as a result(active and reactive parts)

Thank you in advance!
