SigLoss Mask:
{Pass/Fail, No/Yes}
Indicates that the Demodulator is unable to lock to a
signal.
FrmSync Mask:
{Pass/Fail, No/Yes}
Indicates that the framing unit is unable to find the
expected framing pattern.
MFrmSync Mask:
{Pass/Fail, No/Yes}
IFSynth Mask:
{Pass/Fail, No/Yes}
Indicates the Rx IF Synthesizer is not locked. This alarm
will flash ‘On’ during certain modem parameter changes.
BuffPLL Mask:
{Pass/Fail, No/Yes}
Indicates that the Buffer Clock PLL is not locked. This
alarm will flash ‘On’ during certain modem parameter
changes.
RxLevel Mask:
{Pass/Fail, No/Yes}
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 Mask:
{Pass/Fail, No/Yes}
This alarm indicates that a Receive FPGA Hardware
Fault has occurred.
Rx Force:
{Pass/Fails}
Allows a Major Rx Alarm to be forced (for testing
purposes, etc.).
Minor Tx (menu):
Tx Activity (menu):
TerrClk Mask:
{Pass/Fail, No/Yes}
Indicates no Terrestrial Clock activity.
Int Clk Mask:
{Pass/Fail, No/Yes}
Indicates no SCT Clock activity.
BNC Clk Mask:
{Pass/Fail, No/Yes}
Indicates no activity on the External BNC Clock.
TxSatCk Mask:
{Pass/Fail, No/Yes}
Indicates on TX Sat Clock activity.
Tx Data Mask:
{Pass/Fail, No/Yes}
Indicates no Tx Data activity.
TerrAIS Mask:
{Pass/Fail, No/Yes}
Indicates that AIS has been detected in the Terrestrial
Data Stream.
