Adjacent Channel Power—FFT Segments

 

Language Reference

 

SENSe Subsystem

Default Unit:

Hz

Remarks:

You must be in Basic, cdmaOne, cdma2000, W-CDMA

 

(3GPP), W-CDMA (Trial & Arib), or iDEN mode to use

 

this command. Use INSTrument:SELect to set the

 

mode.

Adjacent Channel Power—FFT Segments

[:SENSe]:ACP:OFFSet:LIST:FFTSegment

<integer>,<integer>,<integer>,<integer>,<integer>

[:SENSe]:ACP:OFFSet:LIST:FFTSegment?

Selects the number of FFT segments used in making the measurement. In automatic mode the measurement optimizes the number of FFT segments required for the shortest measurement time. The minimum number of segments required to make a measurement is set by your desired measurement bandwidth. Selecting more than the minimum number of segments will give you more dynamic range for making the measurement, but the measurement will take longer to execute.
