(Trial &
Arib) mode
Returns the frequency-domain spectrum trace data for the
entire frequency range being measured.
With the spectrum view selected
(DISPlay:ACP:VIEW SPECtrum) and the spectrum trace on
(SENSe:ACP:SPECtrum:ENABle):
• In FFT mode (SENSe:ACP:SWEep:TYPE FFT) the number
of trace points returned are 343 (cdma2000) or 1715
(W-CDMA). This is with the default span of 5 MHz
(cdma2000) or 25 MHz (W-CDMA). The number of points
also varies if another offset frequency is set.
• In sweep mode (SENSe:ACP:SWEep:TYPE SWEep), the
number of trace points returned is 601 (for cdma2000 or
W-CDMA) for any span.
With bar graph display selected, one point of –999.0 will be
returned.

Returns 4 comma-separated relative power values for the
reference and offset channels:
1. Reference channel
− relative power
2. Reference channel
− relative power (duplicate of above)
3. Lower offset channel
− relative power
4. Upper offset channel
− relative power
