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)
32/164 This page selects normal or inverted spectrum.
Will exit AUTO-MODE if a manual selection is made.
33/164 This page sets the guard interval between consecutive symbols on
each carrier to prevent inter-symbol interference
Will exit AUTO-MODE if a manual selection is made.
34/164 This page sets up the carrier mode of the receiver front end. The
type of receiver front end may limit the option choice.
Will exit AUTO-MODE if a manual selection is made.
35/164 This page displays the band plan channel spacing. Valid values are
determined by the system hardware.
36/164
This page displays the channel coding (constellation).
37/164 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.
38/164 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.
39/164 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.
310/164 ALPHA = 0 means that it is a non-hierarchical transmission.
311/164 In hierarchy mode, this page allows a selection between high and
low priority streams.
312/164 This page allows the input selection type to be set.
313/164
This page allows the limit Post-Viterbi BER threshold. An alarm is
generated if the BER is above the threshold.
314/164 This page sets the UHF Frequency of the tuner.
UHF Input must be selected on page 12/16.
315/164 This page allows the automatic selection of SPECTRUM
INVERSION, GUARD INTERVAL and CARRIER MODE; Causing
the unit to hunt for the correct setting.
