• Standby transmitter: Reduce values from Tx Power Table
to fixed +25.5 dBm (+23 dBm for 11
GHz) at HPA output, regardless of modulation levels, unless it is already set below that in ATPC
or in RTPC mode
NOTE:
Standby transceiver operates at lower power when in standby mode for energy saving.
Power is automatically increased to the configured level when switched over.
Transmit output power display accuracy in dB
• ± 1.0 dB for the attenuation range, 0 to 3 dB
• ± 2.0 dB for the attenuation range, between 4 dB and the maximum attenuation applicable for
the respective modulation

NOTE.
In this section, Transmit Power is measured at the Antenna Port of a BU in
a 1+0 configuration. Tx Power Table specifies
Guaranteed
Transmit Output Power
values. Guaranteed Transmit Output Power means that the Tx Output Power at the
antenna port is equal or higher than the stated value across the specified
temperature range.
