ACP Spectrum (Adjacent Channel Power)

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. Spectrum trace is a composite trace showing the detected spectrum data used for computing the carrier power and the offset power values as configured by the Carrier and Offset parameters. When measurement averaging is enabled, ACP Spectrum is 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. See ACP Spectrum Trace Data Block Diagram and Detectors and Power Spectrum Analysis for more information.

The spectrum data may have different resolution bandwidth per offset definition, and may have different detectors used for carrier and offset regions.

Marker calculations are disabled on the trace. If marker calculations are desired, use the Spectrum traces for the specific enabled desired detector type.
