4-16
TM065 – Rev. 3.3
Latched Alrm (menu):
Major Tx (menu):
TxProc:
{Pass/Fail}
Tx Processor fault. Indicates a Hardware Transmit DSP
failure within the modem.
TxPower:
{Pass/Fail}
Indicates that the Modem Tx Output Power is within the
allowed tolerance.
TxOSClk:
{Pass/Fail}
Indicates that the Tx Oversample Clock PLL is not
locked. This alarm will flash ‘On’ during certain modem
parameter changes.
CompCLK:
{Pass/Fail}
Indicates that the Tx Composite Clock PLL is not locked.
This alarm will flash ‘On’ during certain modem
parameter changes.
TxSynth:
{Pass/Fail}
Indicates that the Tx IF Synthesizer is not locked. This
alarm will flash ‘On’ during certain modem parameter
changes.
Tx FPGA:
{Pass/Fail}
This alarm indicates a Transmit Hardware FPGA failure
within the modem.
Ref PLL:
{Pass/Fail}
This alarm indicates that the Modem Synthesizers are
not locked to the external reference.
Tx Force:
{Pass/Fails}
Allows a Major Tx Alarm to be forced (for testing
purposes, etc.).
Major Rx (menu):
RxProc:
{Pass/Fail}
Indicates a Receive DSP Hardware failure within the
modem.
SigLoss:
{Pass/Fail}
Indicates that the demod is unable to lock to a signal.
FrmSync:
{Pass/Fail}
Indicates that the Framing Unit is unable to find the
expected framing pattern.
IFSynth:
{Pass/Fail}
Indicates the Rx IF Synthesizer is not locked. This alarm
will flash ‘On’ during certain modem parameter changes.
