9.3 - MONITORING menus (LED C is ON)
This set of menus displays firmware versions and
monitoring information, and is indicated by LED C
on the Programming Unit.
Versions menu
This menu displays the unit's reference number,
Firmware and FPGA (QAM Modulator) versions
and the auto look-up table version for modulation
"Auto Detect" mode.
Ref: 563701
FW: 1.00.0009
FPGA:1.00.04
AUTO:1.03
Input status
This menu displays the status of the input signal,
indicating its lock status. When locked, the
detected input modulation and symbol rate are
displayed.
- INPUT A -
- INPUT A -
STAT: LOCKED
STAT:
MOD:QPSK-2/3
UNLOCKED
SR: 27.500Kb
If "Auto Detect" modulation mode is selected,
the word SEARCHING will blink on the display as
the unit tries to acquire an input signal when the
demodulator is not locked.

STAT:
UNLOCKED
SEARCHING
Output status
This menu displays the status of the output signal,
indicating the output QAM constellation, the QAM
symbol rate and the bandwidth occupied by the
output carrier.

If "Auto Detect" modulation mode is selected, and
if the tuner is not locked, the QAM modulation will
not be displayed, because it will depend on the
input signal acquired.
If the QAM constellation manually selected is not
enough to accommodate the data rate of the input
signal, it will cause an overflow condition, and OVF
will be displayed.
- OUTPUT A -
MOD: 64 OVF
SR:
6.111Mb
BW: 7.028MHz
When the bandwidth of the two output signals
generated by the QAM transmodulator and their
frequencies are such that overlap each other, it is
indicated by the message OVERLAP!.
- OUTPUT A -
MOD: 256QAM
SR:
4.583Mb
OVERLAP!
When the input SNR falls below a certain
modulation dependent threshold (rain fade), the
output QAM signal is muted to avoid artifacts in
the reception and the message "RAIN FADE!" is
displayed.
Input measurements
This menu displays the current input SNR, the
minimum input SNR recorded, and the number of
tuner unlock conditions.
