To couple spectrum displays
The settings for one or more spectrums can be coupled. Thus, if any FFT setting for
any of the coupled spectrums are changed, they are changed for all coupled spec-
trums.
1. Open [FFT] > "FFT setup" > "Overlap" tab.
2. Select the spectrums that you need to couple. You cannot select the spectrum for
the currently selected math waveform. Its settings are applied to the selected spec-
trums.
3. If necessary, define an FFT function to be used for the coupled math waveforms so
that a spectrum is displayed. See Chapter 7.3.1, "Displaying math waveforms" ,
on page 257.

9.1.3.1 FFT setup
Access: [FFT] > "FFT setup" > "Setup" tab
In this tab, you define the settings for the FFT window. The display can be restricted to
the results for a certain time base extract and to a specified frequency range.
Additional settings are available on this tab if the Spectrum analysis option
(R&S
RTO6-K37) is installed.
See Chapter 9.2.4, "Spectrogram configuration settings" , on page 392.
