• INPUT BROWSE — when "activated" the input browse function
automatically scans the input signal for the 8VSB/QAM rates
as per the chart below. Then, if found, automatically sets the
input and output parameters. If no valid signal is found it will
default to the last locked state. Factory default is 8VSB.
• INPUT DEMOD — permits the selection of any of the listed
input demod modes, the unit is factory set for 8VSB signals
• INPUT RATE — permits the entry of the desired input baud
rate, this is automatically set to one of the factory values listed
above (input browse) if a standard 8VSB input signal is used
or the input browse function is activated
• OUT QAM — permits the entry of the desired output QAM
mode, the unit has six available QAM modes
• ALPHA — permits the entry of the appropriate alpha setting to
match the output QAM mode
• INTERLEAVER — permits the entry of the appropriate
interleaver setting to match the output QAM mode
• OUT BD RATE — permits the entry of the desired output QAM
baud rate. The QAM output baud rate is automatically set to
the corresponding values for the respective input baud rate as
listed in the chart below.
