Module: DOCS-PNM-MIB
OID (symbolic): DOCS-PNM-MIB::docsPnmCmDsConstDispModOrderOffset
OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.2.4.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute specifies an offset from the lowest order modulation for the data subcarriers in any of the profiles in the downstream channel. If the lowest order modulation order that the CM was receiving was 1024-QAM and the ModulationOrderOffset was zero, then the CM would capture the soft decision samples for all of the subcarriers which were using 1024-QAM modulation order. If the ModulationOrderOffset was 1, then the CM would capture the soft decision samples for all of the subcarriers using the next highest modulation order in use for the profiles in the downstream channel.
This value can only be changed while a test is not in progress. An attempt to set this value while the value of 'docsPnmCmDsConstDispMeasStatus' is 'busy' will return 'inconsistentValue'.
What is docsPnmCmDsConstDispModOrderOffset?
An offset (0-10) from the lowest modulation order used by any profile on the downstream channel, selecting which modulation-order subcarriers to capture for the constellation display. An offset of 0 captures the lowest-order (most compressed/robust) subcarriers in use; increasing it steps up to progressively higher-order QAM subcarriers.
