Spectrum—FFT Minimum Points in Resolution BW
[:SENSe]:SPECtrum:FFT:RBWPoints <real>
[:SENSe]:SPECtrum:FFT:RBWPoints?
Set the minimum number of data points that will be used inside the
resolution bandwidth. The value is ignored if length control is set to
manual. This is an advanced control that normally does not need to be
changed.
Factory Preset
and *RST: 1.30
Range: 0.1 to 100
Remarks: To use this command, the appropriate mode should be
selected with INSTrument:SELect.
Spectrum—Window Delay
[:SENSe]:SPECtrum:FFT:WINDow:DELay <real>
[:SENSe]:SPECtrum:FFT:WINDow:DELay?
Set the FFT window delay to move the FFT window from its nominal
position of being centered within the time capture. This function is not
available from the front panel. It is an advanced control that normally
does not need to be changed.
Factory Preset
and *RST: 0
Range:
−10.0 to +10.0s
Default Unit: seconds
Remarks: To use this command, the Service mode must be
selected with INSTrument:SELect. In Service mode, it
is possible to get an acquisition time that is longer than
the window time so that this function can be used.
Spectrum—Window Length
[:SENSe]:SPECtrum:FFT:WINDow:LENGth <integer>
[:SENSe]:SPECtrum:FFT:WINDow:LENGth?
Set the FFT window length. This value is only used if length control is
set to manual. This is an advanced control that normally does not need
to be changed.
Factory Preset
and *RST: 706
