Status Display (Optional )
This indicator shows the general status of the Outdoor SSPA – if everything is good, or if an
error condition has occurred, or if the unit has been manually disabled by mute control. Also,
the operating status of a Master/Slave redundant pair is reflected.
Booster Temperature Display (Optional )
Using the UPCOM TECHNOLOGIES Monitor and Control Software, a thermometer display
with a numeric readout of the baseplate temperature of the unit in degrees Celsius is shown.
The baseplate temperature typically experiences a 20 to 30 degree rise above ambient on the
highest power Outdoor SSPAs and 15 to 20 degree rise on lower power units. This display
corresponds with the Temperature Monitor outlined in the analog M&C section above.
Output Power Display (Optional )
A numeric readout of the output power level is displayed in units of dBm. The indicator is
calibrated at the factory using the middle frequency of the SSPA, and has approximately a 20
dB dynamic range. When this range is exceeded, the readout shows “Low” or “High”
depending on which particular limit has been reached.
Overheated Alarm (Optional )
This alarm indicates when the unit’s baseplate rises above about 85 ºC, which is an
overheated condition. The unit will automatically enter into a muted state. This function has
approximately a 20 ºC hysteresis window which will allow the SSPA to re-enable itself when
the temperature is reduced by 20 ºC at the baseplate.
PS Voltages Monitor (Optional )
The output voltage levels of the Power Supply are monitored and this alarm indicates when
any of them fall below a preset level. Three voltages are monitored: +12 V feeding the
Booster Amplifier and –5 V from the bias assemblies attached to the Booster Amplifier. The
unit will enter a muted state when this alarm is active.
Manual Control Enable/Disable and Mute Input (Optional )
A manual mute control can be accessed from the Enable/Disable button of the software. For
systems set up for 1:1 Redundant operation, this control is also used for manually selecting the
Active unit in a redundant pair.
Mate Status (Optional )
In redundant configurations, the Mate Status indicates the mute condition of its mate. That is,
the Master display shows the Slave condition, and the Slave display shows the Master
condition.
Attenuator Control (Optional )
System conversion gain can be changed here provided an attenuator module has been
installed. The range of control is from 0 dB (no attenuation applied) to 20 dB (20 dB of gain
reduction) in 0.5 dB steps. The value may be stepped up or down, or entered directly with the
keyboard by highlighting the entry field. Note that this control is dependent on an installed
hardware option. If it is not installed, this control will not have any effect.
