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
