Set the desired clearance (between -10 dB and 0 dB) from the
spectral mask. The default setting is -1 dB, which will maintain
a 1 dB clearance from the mask for maximum efficiency. This
settings will not cause any reduction in output power.
Select ON to enable a reduction in IBOC injection (digital
power) if the spectrum mask requires it. Select OFF to disable
this setting.
Select ON to allows the optimizer to adjust the PA voltage
setting to maximize efficiency based on the transmitter
output spectrum. Depending on other settings in this section,
it may require other actions to maintain the transmitter’s
compliance. Select OFF to disable. When disabled, other HD
Optimizer settings will have no effect.
Select ON to enable a reduction in the power set-point if the
spectrum mask requires it. Select OFF to disable this setting
.
Sets the value (between -10 db and 10 dB) that is considered
to be absolutely required. If this level is exceeded, the digital
power from the transmitter will be reduced if the PA voltage
is at maximum. If the spectral mask still cannot be met and
the setting for it is enabled, the transmitter power set-point
will be reduced. Default setting is 0.0 dB.
