docsPnmCmtsUsSpecAnSpan

Module: DOCS-PNM-MIB

OID (symbolic): DOCS-PNM-MIB::docsPnmCmtsUsSpecAnSpan

OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.3.8.1.8

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute determines the frequency span of the Spectrum Analysis capture if the trigger mode is FreeRunning. If the trigger mode is not FreeRunning, the CMTS determines the value for the Span attribute.

This object cannot be changed while a capture is in progress. It will return a value of 'inconsistentValue' if set while the value of 'docsPnmCmtsUsSpecAnMeasStatus' is set to a value of 'busy'.

What is docsPnmCmtsUsSpecAnSpan?

A deprecated setting for the frequency span, in the same units as related capture objects, of the spectrum-analysis capture when TriggerMode was 'FreeRunning'; otherwise the CMTS determined the value itself. STATUS is 'deprecated'; replaced by docsPnmCmtsUtscCfgSpan in the newer Upstream Triggered Spectrum Capture objects.
