ACP Results (Adjacent Channel Power)

The ACP Results table shows power measurement information about Offsets configured for the Adjacent Channel Power measurement. When measurement averaging is enabled, the values in ACP Adjacent Channel Power: The power from a modulated communications channel that leaks into an adjacent channel. This leakage is usually specified as a ratio to the power in the main channel, but is sometimes an absolute power. Results are computed from the averaged detected spectrum data. See ACP Spectrum Trace Data Block Diagram and Detectors and Power Spectrum Analysis for more information.

ACP Results is a type of Matrix Table that provides sortable rows by column, selectable column visibility, and copy/paste and export functionality to share rows of content or complete tables to applications like email, text editing or spreadsheet programs.

Offset identifies the offset for the row (corresponds to offsets configured in the Offsets & Limits parameter tab).	Offset Frequency indicates the beginning of the frequency region used for evaluating the offset power. The frequency is presented relative to the Carrier Reference Frequency. Lower offset evaluation is below the Carrier Reference Frequency and Upper offset evaluation is above Carrier Reference Frequency.	Integ BW is the -3 dB resolution bandwidth used for the offset power measurements, as defined by Offset parameters.	Lower (dBc) is the power measured at the Lower Location relative to the defined Power Reference. The result units depend on Reference Power Calculation (dBc for Integrated Power, dB for PSD Power Spectral Density: See power spectral density.).	Lower (dBm) is the power measured at the Lower Location. The result units depend on Reference Power Calculation (dBm for Integrated Power, dBm/Hz for PSD).	Lower Status indicates the Lower Offset limit test result (Pass, Fail, or Not Tested).	Lower (Ref.) is the Lower Location's reference power such that Lower (Ref.) + Lower (Rel.) = Lower. The result units depend on Reference Power Calculation (dBm for Integrated Power, dBm/Hz for PSD).	Lower Reference indicates which carrier(s) are used for the power reference calculation. This result is useful when multiple carriers are enabled. When Left and Right Subblocks is selected as the Power Reference Source, reference subblock(s) are shown in this column.	Upper (dBc) is the power measured at the Upper Location relative to the defined Power Reference. The result units depend on Reference Power Calculation (dBc for Integrated Power, dB for PSD).	Upper (dBm) is the power measured at the Upper Location. The result units depend on Reference Power Calculation (dBm for Integrated Power, dBm/Hz for PSD).
