[:SENSe]:ACP:OFFSet[n]:LIST[n]:BANDwidthBWIDth?

Define the custom resolution bandwidth(s) for the adjacent channel power testing. If there is more than one bandwidth, the list must contain five (5) entries. Each resolution bandwidth in the list corresponds to an offset frequency in the list defined by [:SENSe]:ACP:OFFSet[n]:LIST[n][:FREQuency]. You can turn off (not use) specific offsets with the [:SENSe]:ACP:OFFSet[n]:LIST[n]:STATe command.

Offset[n]

n=1 is base station and 2 is mobiles. The default is base

 

station (1).

List[n]

 

cdmaOne mode n=1 is cellular bands and 2 is pcs bands. The default is cellular.

W-CDMA (Trial

&Arib) mode n=1 is ARIB, 2 is 3GPP, and 3 is Trial. The default is ARIB (1).
