BuffPLL:
{Pass/Fail}
Indicates that the Buffer Clock PLL is not locked. This
alarm will flash ‘On’ during certain modem parameter
changes.
RxLevel:
{Pass/Fail}
This alarm indicates that the Receive Automatic Gain
Control is saturated (i.e., too much signal power is being
supplied to the modem).
Rx FPGA:
{Pass/Fail}
This alarm indicates that a Receive FPGA Hardware
fault has occurred.
Minor Tx (menu):
Tx Activity (menu):
TerrClk:
{Pass/Fail}
Indicates no Terrestrial Clock activity.
Int Clk:
{Pass/Fail}
Indicates no SCT Clock activity.
BNC Clk:
{Pass/Fail}
Indicates no activity on the External BNC Clock.
TxSatCk:
{Pass/Fail}
Indicates no Tx Sat Clock activity.
Tx Data:
{Pass/Fail}
Indicates no Tx Data activity.
TerrAIS:
{Pass/Fail}
Indicates that AIS has been detected in the Terrestrial
Data Stream.
RS FIFO:
{Pass/Fail}
Indicates the status of the Tx Reed-Solomon FIFO.
Minor Rx (menu):
BufUFlw:
{Pass/Fail}
Indicates that a Doppler Buffer underflow has occurred.
BufOFlw:
{Pass/Fail}
Indicates that a Doppler Buffer overflow has occurred.
Buf<10%:
{Pass/Fail}
Indicates that the Doppler Buffer has gone below 10%
full and may underflow.
Buf>90%:
{Pass/Fail}
Indicates that the Doppler Buffer has gone above 90%
full and may overflow.
