Spectrum (Average) (Adjacent Channel Power)

Spectrum (Average) displays the output from the Average detector. When measurement averaging is enabled, Spectrum (Average) is the average of Inst Spectrum (Average), averaged over the number of traces specified in the Count field, and the averaging type and count (e.g.," RMS:10") are displayed at the top of the trace's display. When measurement averaging is disabled, the Spectrum (Average) and Inst Spectrum (Average) displays are identical.

See ACP Spectrum Trace Data Block Diagram and Detectors and Power Spectrum Analysis for more information.

The Spectrum (Average) trace data only appears when the Average detector is enabled.

Spectrum (Average) may be channelized when multiband spectrum is in use, providing trace results for each spectrum/measurement channel shown on the Frequency tab.
