quency definition.
Remote command:
[SENSe:]FREQuency:CENTer on page 1025
Numerator
Defines the numerator of the frequency-defining factor.
Note that this factor also affects the (absolute) Notch Bandwidth (Absolute / Relative to
Channel BW) and the "Frequency Offset per Notch" on page 225.
Remote command:
CONFigure:GENerator:NPRatio:FREQuency[:FACTor]:NUMerator
on page 909
Denominator
Defines the denominator of the frequency-defining factor.
Note that this factor also affects the (absolute) Notch Bandwidth (Absolute / Relative to
Channel BW) and the "Frequency Offset per Notch" on page 225.

7.5.7 How to Perform NPR Measurements
Measuring the noise power ratio is a very easy and straightforward task with the
R&S FSW.
1. From the "Overview", select "Frequency".
2. Define the "Center Frequency" of your channel.
3. From the "Overview", select "Select Measurement".
4. Select "Noise Power Measurement".
The measurement is started immediately with the default settings.
5. Select the "NPR Config" softkey.
6. Specify the "Channel Bandwidth" of your entire channel.
7. If necessary, define an appropriate span.
8. Enter the "Number of notches" in your signal.
