In order analysis instrument mode (INST:SEL ORD; Option 1D0) you may specify one of the following
windowing functions:
Hanning
flattop
uniform
The windowing function is not available in octave analysis instrument mode (INST:SEL OCT; Option
1D1) and swept sine instrument mode (INST:SEL SINE; Option 1D2).
In correlation analysis instrument mode (SEL:INST CORR), this command specifies the correlation
weighting function.
To select the uniform function, send WIND UNIF. The uniform weighting function (- T/2, T/2) does not
suppress any part of the time record. This function should be used for signals which may be considered
self-windowing, such as transients, bursts and periodic waveforms.
To select the Zero Pad 0, T/2 function, send WIND LAG. The function suppresses the last half of the
time record and passes only the first half.
To select the Zero Pad -T/4, T/4 function, send WIND LLAG. The function suppresses the first quarter
and the last quarter of the time record, and passes the center part of the time record (the second and third
quarters).
The channel specifier is ignored for the uniform, Zero Pad 0,T/2 (LAG), and Zero Pad -T/4,T4 (LLAG)
window functions.
See Online Help for additional information about correlation's weighting functions.
