r/w
Unsigned32
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'.
