{SYMBOL RATE DATA RATE AUTO}
Indicates the rate (symbol or data) which is maintained
when associated parameters (i.e. Modulation, Inner FEC
Code Rate, Terr Framing) are changed. For example, if
the Last Rate Control is set to "Symbol Rate" and the
modulation is subsequently changed, the system will
attempt to maintain the same symbol rate by adjusting
the data rate. If the Last Rate Control is set to "Data
Rate" and the modulation is subsequently changed, the
system will attempt to maintain the same data rate by
adjusting the symbol rate.
The "Auto" Setting of Last Rate Control causes the last
explicitly changed rate (symbol or data) to be maintained
when associated parameters are changed. For
example, if the last rate control is set to "Auto" and the
Data Rate is subsequently explicitly changed, any
subsequent changes to Modulation or Inner FEC Rate
would cause the symbol rate to be adjusted in order to
maintain the Data Rate.
