	Language Reference
	SENSe Subsystem
	RFBurst for MS
Remarks:	You must be in Basic, cdmaOne, iDEN, NADC, or PDC
	mode to use this command. Use INSTrument:SELect to
	set the mode.
	In Basic mode, for offset frequencies >12.5 MHz, the
	external triggers will be a more reliable trigger source
	than RF burst. Also, you can use the Waveform
	measurement to set up trigger delay.

Adjacent Channel Power—Power Reference

[:SENSe]:ACP:TYPE PSDRefTPRef

[:SENSe]:ACP:TYPE?

Selects the measurement type. This allows you to make absolute and relative power measurements of either total power or the power normalized to the measurement bandwidth.

Power Spectral Density Reference (PSDRef) - the power spectral density is used as the power reference

Total Power Reference (TPRef) - the total power is used as the power reference

Factory Preset
and *RST:	Total power reference (TPRef)
Remarks:	You must be in the Basic, cdmaOne, cdma2000,
	W-CDMA (3GPP), W-CDMA (Trial & Arib), NADC, or
	PDC mode to use this command. Use
	INSTrument:SELect to set the mode.
