106 205486 REV F Operations Manual, HPA2, Compact Outdoor SSPA
11.1.1.3 Sys Info Page 3
This page reflects various SSPA faults and conditions.
• BUC – Displays the block upconverter (BUC) fault (if equipped). Values “Fault” or
“Normal”;
• Aux – Displays the auxiliary fault condition. Values – “Fault” or “Normal”;
• Int.Mute – Displays the internal mute condition (mute state controlled by internal
SSPA hardware, such as serial protocol command or automatic over temperature
shutdown). Values – “Off” or “On”;
• Ext.Mute – Displays the external mute condition (Mute condition controlled by
hardware jumper on M&C connector). Values – “On” or “Off”;
• State – Displays the SSPA online state in a redundant system. Value – “Standby”
or “Online”;
• Ctrl – Displays the type of attenuation control. Values – “Analog” or “Serial”.
11.1.1.4 Sys Info Page 4
This page shows the detailed information about the state of the SSPA‘s internal power supply
characteristics, as well as the state of external wave-guide RF switch (if equipped).
• DCCur.(A) – The total DC current draw by the RF module from the main power
supply with an accuracy of 0.1A. This value varies depending on the power level of
SSPA. If the SSPA is in the mute state, the current drops to a 0 to 5A range.
• Regul.(V) – Displays the measured value of the internal RF module voltage
regulator. The value in normal mode should be range from 8 to 10.5V. During
SSPA mute period, this value drops to near 0V. Measurement is accurate to within
0.1V.
• Gate (V) – This value represents the negative GaAsFETs gate drive voltage.
Normal value range is 1 to 6 V. The value reading may be affected by SSPA
temperature changes and mute state.
• PS (V) – Displays the internal power supply voltage output. Normal range is 11 to
13 V, with an accuracy to within 0.1V.
• RFSW – Displays the state of the external wave-guide RF switch. This reading is
valid only when the SSPA configured for internal 1:1 redundancy mode. Possible
states are “Fault” or “Normal”.
11.1.1.5 Sys Info Page 5
This page displays the SSPA serial communication and redundancy related settings.
• Prtcl. – Displays the type of default implemented serial protocol. Values: Binary,
String or Terminal.
• Baud – Displays the default SSPA baud rate. Values: 2400, 4800, 9600, 19200,
38400.
• Addrs – Displays the SSPA serial network address. Values: 0 to 255.
• Unit – Displays the SSPA 1:1 redundancy topological factor. Values: “HPA1” or
“HPA2”.
• Mode – Displays the implemented redundancy mode. Values: “Standalone” or “1:1”.
