Hpa Assembly; Controller Board - Advantech SSPBMg–C200–BRE Installation And Operating Manual

SSPBMg-C200-BRE
2.2.4 HPA A
SSEMBLY
The HPA Assembly amplifies the RF signal from the Up-Converter Assembly to a power level
sufficient for transmission. Integral to this module are three HPA stages and a power conditioner
board. Other functionality includes internal power conditioning and overtemperature shutdown.
2.2.5 C B
ONTROLLER OARD
All of the controls, input/output communication and the decision-making, with the exception of
the critical module-level decision are performed by the micro-controller within the Up-
Converter. The Controller Board provides through the System Control interface:
• Fault detection and indication
• Forward RF power monitoring and indication (optional)
• Temperature monitoring and indication
• ON/OFF transmit switching
• Change in the unit's address
An ALARM will be triggered when the internal temperature of the SSPB exceeds 70°C. The
SSPB will continue to operate in this condition.
A FAULT signal will be sent to the user if any one of the following occurs:
• Phase-locked loop oscillator within the synthesizer is out of lock.
• The baseplate temperature exceeds 85 °C
• Any of the RF devices fails
In case of over-temperature (>85 °C), the SSPB will automatically restart when its internal
temperature decreases to 60 °C.
