Output Power: The output power setting, as displayed in the Output Power screen, varies
with transmitter type and the IBOC Mode setting. Refer to Tables 3-1 and 3-2 for maximum
and minimum power ratings.
NOTE
The power levels in the following tables are for reference only.
The power capability will vary vs frequency and MP mode (e.g. MP3). In addition, if the
Spectrum/Efficiency Optimizer is enabled, but the transmitter spectrum limits cannot be
achieved, the injection level and/or power level set-point will be reduced, if configured to
permit these reductions. Refer to Section 3.1.3.2 for more information on configuring the
Spectrum/Efficiency Optimizer.
NOTE
In IBOC mode of operation, the output power level varies with frequency for the VSHD
transmitter system. Tables 3-1 and 3-2 are referenced at 98 MHz.
HD PowerBoost is now standard in VS SW 4.4 or later.
