docsPnmCmtsUsImpNoiseMeasBw
Module: DOCS-PNM-MIB
OID (symbolic): DOCS-PNM-MIB::docsPnmCmtsUsImpNoiseMeasBw
OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.3.4.1.6
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute defines the bandwidth for the noise power measurement. The MeasurementBw is the -3 dB bandwidth; the occupied bandwidth is typically 1.25 times the measurement bandwidth.
This object cannot be changed while a capture is in progress. It will return a value of 'inconsistentValue' if set while the value of 'docsPnmCmtsUsImpNoiseMeasStatus' is set to a value of 'busy'.
What is docsPnmCmtsUsImpNoiseMeasBw?
The -3 dB measurement bandwidth, in kHz, for the impulse-noise power measurement, selectable among 160/320/640/1280/2560 (default)/5120 kHz; the actual occupied bandwidth runs about 1.25x this value. An admin widens or narrows this to trade sensitivity to a specific ingress signal's bandwidth against overall noise-floor averaging.
