Module: DOCS-IF3-MIB
OID (symbolic): DOCS-IF3-MIB::docsIf3CmSpectrumAnalysisMeasTotalSegmentPower
OID (numeric): 1.3.6.1.4.1.4491.2.1.20.1.35.1.3
Node type: OBJECT-TYPE
Type: TenthdB
Access: read-only
Description: This attribute provides the total RF power present in the segment with the center frequency equal to the Frequency index and the span equal to the SegmentFrequencySpan. The value represents the sum of the spectrum power in all of the associated bins. The value is computed by summing power (not dB) values and converting the final sum to TenthdB.
What is docsIf3CmSpectrumAnalysisMeasTotalSegmentPower?
This object reports the total RF (radio frequency) power measured across a defined frequency segment and time window on a cable modem's receive spectrum, computed by summing the power values across individual frequency bins. The power is expressed in tenths of a decibel (dB), a logarithmic unit commonly used in radio engineering. Cable network technicians use this measurement to diagnose signal quality problems and verify that the modem is receiving adequate power levels from the cable network.
