Input measurements
This menu displays the current input SNR, the
minimum input SNR recorded, and the number of
tuner unlock conditions.
SNR INPUT A
NOW:
20.1dB
MIN:
14.3dB
#Unlock:

This menu will not be displayed if the input is
DISABLED.
The minimum SNR and unlock counters can be
reset by pressing and holding the
approximately 2 seconds. These values are stored
in nonvolatile memory so they are not erased
otherwise, even when the unit loses power or is
turned off.
Any change to the input parameters (frequency,
modulation, channel table, etc.) automatically
resets these counters.
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.

In case of QAM annex A as output mode, the QAM
constellation and baud rate have to be manually
selected. It might not be possible for a given
combination to accommodate the data rate of
the input signal. The same can happen in case of
annex B, if the input modulation is 256QAM and
the putput is 64QAM. In that case an overflow
condition will occur and the alarm message "QAM
OVF!!" will be displayed.

If both otput QAM signals overlap each other in
frequency, the alarm message "OVERLAP !!" will be
displayed.
When the user has selected one of the special
modes (CARRIER WAVE, MUTED or NULL MODE)
a message will also be displayed to signal this
condition.
Output measurements
This menu shows the occupancy of the output, i.e.,
the percentage of the output baud rate occupied
by useful data. The rest of the output transport
capacity is filled up with null packets.

The maximum registered occupancy is also shown
and can be reset by pressing and holding the
for a few seconds.
If the selected output modulation or baud rate (in
case of QAM annex A) does not provide enough
output capacity to accomodate the input data rate
and overflow condition will occur and a warning
message "Overflow!" will be displayed.
This menu will not be displayed if the output is in
CARRIER WAVE, NULL or MUTED mode.
Temperature menu
This menu shows the current internal temperature
and the maximum internal temperature recorded
(F).
The maximum value is stored in nonvolatile
memory for monitoring purposes.
