Correlation Windows:
When the measurement group is Correlation, the available windows are:
[-T/2..T/2]
This is a uniform window which should only be used on data which is self windowing
(lasts less than half of the time record).
[0..T/2]
This window zeroes the second half of the time record.
[-T/4..T/4]
This window zeroes the first and last quarter of the time record.
Octave, Swept Sine, and Time/Histogram measurements do not use windows.
Channel 1 Window
Selects whether the Force or Exponential window is applied to the Channel 1 input. This
softkey is only active if the selected window is Force/Exponential.
Command: W1FE (?) {, i}
Channel 2 Window
Selects whether the Force or Exponential window is applied to the Channel 2 input. This
softkey is only active if the selected window is Force/Exponential.
Command: W2FE (?) {, i}
Force Length
Set the Force Window Length. The maximum value that can be entered is the length of
the FFT time record. Points in the time record up to the Force Length are unmodified.
Points in the time record past the Force Length are zeroed.
Choose Force/Exponential as the window before setting the Force Length.
Command: FWFL (?) d {, i}
Expo TC
Set the Expo Window Time Constant as a percentage of the FFT time record
[5%..1000%]. This is the point where the window function reaches 1/e.
Choose Force/Exponential as the window before setting the Expo Time Constant.
Command: FWTC (?) d {, i}
