3.9.1.1 Signal Indicators
Three rows of LEDs show the connection status of the connected amplifier. Top-most is an
indicator that displays a green LED when Connected, or a red LED when Disconnected.
Immediately below are two LEDs for the TX and RX paths. The LED in the third row displays
the mute state (Carrier Enable). This is actually a toggle which allows the user to Enable or
Mute the amplifier.
3.9.1.2 Fault Status Indicators
The Fault Status frame in the lower left side of the Status Window contains 12 SSPA fault
lights that correspond to :

3.9.1.2 Fault Status Indicators
The Fault Status frame in the lower left side of the Status Window contains 12 SSPA fault
lights that correspond to :
Summary Alarm: The Summary Alarm is simply a logical ‘OR’ of any of the alarm indicators.
Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value.
BUC Alarm: The BUC fault is only active in units that are supplied with an optional L-Band
Block Up Converter module. If the Up Converter’s phase locked local oscillator loses lock, a
BUC alarm is set and the amplifier is muted so that spurious RF can not be transmitted to the
satellite.
Auxiliary & Spare Alarms: The Auxiliary and Spare Alarms are configurable from the
Settings Window. See Section 3.9.2.
High Temperature Alarm: The Temperature Fault indicator is factory preset to alarm at 80°
C. The amplifier will continue to operate up to 90°C. Beyond 90°C the DC power will be
interrupted to the SSPA module. This measure will protect the sensitive microwave transistors
from catastrophic failure. The fans and monitor and control circuitry will continue to operate
normally. This function has approximately a 5°C hysteresis window which will allow the
amplifier to re-enable itself when the ambient temperature is reduced by 5°C. The
Temperature Alarm is intended to warn the operator of possible fan problems and eventual
amplifier shutdown.
Low DC Voltage Alarm: The Voltage Alarm is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value.
Calibration Table: The Cal Table Alarm is used under initial test at the factory.
Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value.
BUC Alarm: The BUC fault is only active in units that are supplied with an optional L-Band
Block Up Converter module. If the Up Converter’s phase locked local oscillator loses lock, a
BUC alarm is set and the amplifier is muted so that spurious RF can not be transmitted to the
satellite.
