General Operation Overview
1. The “Adjust Gain” option allows the user to
control the total gain of the system. Valid gain
settings range from 55 dB to 80 dB. If the user
selects to configure the downlink gain, the uplink
gain will automatically be set to the same value. In
order to override this condition, the user will have
to select the uplink option and adjust the gain to the
desired value.
3. “Filter Programming” allows the user to
select and program one of the loaded filters on
the system. Please note that as with option 2, the
GPS task needs to be disabled otherwise the
filter selection will be overridden by the current
location of the system.
2.“Select Active filter” can be used to toggle
between the filters loaded for test Purposes. Please
note that in order for this to work properly, the GPS
task needs to be disabled otherwise the filter
selection will be overridden by the current location
of the system.
4. The “PA Output Control” menu selection
allows the user to control the state of the power
amplifier, ON or OFF. The setting overrides all
other PA control tasks and is persistent across
reboots. Care must be taken to insure the user is
aware of the state of this setting so as to
eliminate false keyed/de-keyed states.
5. “PA Oscillation Control” enables the user to
toggle the oscillation control feature off and on.
When enabled this feature detects oscillations and
adds attenuation until the oscillations are
suppressed.
