Note: In measurement functions for which users cannot select Post FFT, this menu line
is grayed out. In this case, there are two options:
1. FFT is not needed by any currently selected measurement and is therefore not com-
puted in order to save time. There is no live FFT in the FFT graph.
2. FFT is needed by at least one selected measurement (e.g. phase measurement,
precision frequency measurement) and cannot be deactivated. The internally used FFT
can be displayed in the FFT graph.
"deactivated" Post FFT deactivated.
Recommended for increasing the measurement speed (e.g. for
sweeps or remote control).
"activated" Post FFT activated; the associated measurement function defines the
remaining settings dynamically.
Remote command:

5.26.4 FFT Measurement Function
The "FFT" can be selected as a separate measurement function (Function FFT).
Unlike the other FFT analyses, all FFT parameters can be determined by the user.
The following additional functions are also available:
●
Delay compensation
●
DC suppression (digital only)
●
Filtering (2 user-definable filters)
