BLACkharris
The Blackman window is bell shaped and has a poor frequency
resolution, but very good amplitude accuracy. It is recommended
mainly for signals with single frequencies to detect harmonics.
GAUSsian
Good frequiency resolution and best magnitude resolution, rec-
ommended for weak signals and short duration
FLATTOP2 = FLATtop2
The flattop window has a poor frequency resolution, but the best
amplitude accuracy and the sharpest side lobe. It is recommen-
ded for accurate single-tone amplitude measurements.
KAISerbessel
The Kaiser-Bessel window has a fair frequency resolution and
good amplitude accuracy, and a very high sidelobe level. It is
recommended for separating two tones with differing amplitudes
and a small frequency distance.

Firmware/software: Version 3.35 and higher: Use FLATTOP2 or FLATtop2 instead of
FLAT2
CALCulate:MATH<m>:FFT:FRAMe:ARIThmetics <Arithmetics>
The arithmetic mode defines how the final FFT result is calculated from the individual
frame results.

Usage: Asynchronous command
CALCulate:MATH<m>:FFT:FRAMe:COVerage?
Due to the restriction of the number of frames (see CALCulate:MATH<m>:FFT:
FRAMe:MAXCount on page 1321), the waveform may only be analyzed partially. This
command queries the percentage of the trace that was analyzed, i.e. which part of the
trace was included in the frame calculation.
