Warning reason/triggering
condition
The demodulation switch
and the Warning switch of
the input port are turned on
and the signal is not locked.
It is likely that the signal
wire is not connected or the
parameter setting is wrong.
Reason:
1) FPGA configuration fails
and the logical operation of
daughter card is wrong;
2) The equipment operation
is abnormal. If the restart is
invalid, the hardware may
fail.
Triggering: it is detected
that the status register of
the daughter card logic is
abnormal.
Reason: failed
configuration of daughter
card
Triggering condition: FTP
fails to upload the correct
FPGA configuration file.
When the demodulation
input detects that the data
package is lost (more than
20 times per second
generally), the warning may
be outputted.
When the demodulation
input detects that the PAT
table content is wrong, it is
likely that the tuner mistake
causes the abnormality of
demodulation data.
The demodulation chip of
board card fails in the
initialization. It is likely that
the hardware fails.

Resolution
Check whether the input
source signal is normal and
check whether
frequency point parameter
setting is correct.
1) Replace
logical configuration file. It
is unnecessary to restart
the equipment.
2) Return and repair of
equipment

configuration
restart the equipment.
Check the input signal wire;
check the input
source; insert the signal
wire and etc. again; or
replace the card to make
the test.
Wait the board card to
recover or

Restart the equipment or
replace the card slot. If it is
still unable to solve the
problem, replace the card.
