Hello,

I am trying to use measured S parameter data to perform some analysis and calculation. However, i am not sure if PNA measurement is done as a function of frequency or angular frequency. Thank you in advance.

they are done as a function of frequency where:

f = W/2Pi

Hello daras,

Thank you for the reply. So the S Parameter data displayed on S21 is as function of frequency or angular frequency?

Thank you

Yes - when you setup a standard channel with sweep type set to linear or log frequency, then the independent variable on the x-axis of the displayed s-parameters is frequency.

where the measure for frequency is cycles/second, or Hz (not radians/sec).
