C.7.4 Terrestrial Receiver Input Menu Pages (to version
2.5.4)
This section applies to models M2/PTR/942 and M2/PTR/948B[C] (to

version 2.5.4).

The input is the UHF connector.

Description
This page dynamically displays the current Post-Viterbi BER value.
This is the value shown on the front panel BER meter. Also shows
the status of the Signal Degradation mode (DEG ON | OFF)
32/134
This sets up the channel number and tuner frequency offset for the
8MHZ required service. The channel number and offset are limited to the
OFF: +3 applicable range of the tuner.
33/134 This page sets the guard interval between consecutive symbols on
each carrier to prevent inter-symbol interference.
34/134 This page sets up the carrier mode of the receiver front end. The
type of receiver front end may limit the option choice.
35/134 This page displays the band plan channel spacing. Valid values are
determined by the system hardware.
36/134 This page displays the channel coding (constellation).
37/134 ALPHA ¹ 0: This non-editable page displays the HIGH and LOW
FEC code rates when the transmission is hierarchical.
LOW 2/3 ALPHA = 0: This non-editable page displays a single FEC RATE
when the transmission is non-hierarchical.
38/134 A test mode which degrades the incoming signal. The status on the
signal degradation is shown on page 1 (DEG ON | DEG OFF)
See CAUTION following this table.
39/134
This page displays the number of errors in a single packet after
Viterbi correction.
·
If the error is 15 or more, GREATER THAN 255 ERRORS is
displayed.
·
If the input is not locked, INPUT NOT LOCKED displayed.
311/134 ALPHA = 0 means that it is a non-hierarchical transmission.
311/134
In hierarchy mode, this page allows a selection between high and
low priority streams.
312/134 Allows the input connector to be chosen. Choices available depend
on the Tuner type.
See CAUTION following this table.
313/13 This page allows the limit Post-Viterbi BER threshold. An alarm is
generated if the BER is above the threshold.
