Extend Low Band
The software maintains a Mode Global value called Extend Low Band.
Under the current sweep configuration crossing over two bands, when Extend Low
Band is turned ON, the instrument checks whether one band can cover the whole
sweep frequency range or not. If it can, then the instrument locks the band;
otherwise, it does nothing (the band crossover occurs).
This function does not work when Band Lock under System > Service > Lock
Functions is not -1 (no Band Lock). In that case, Band Lock takes priority over
Extend Low Band.
This function resets to OFF when "Restore Defaults" on page 2037 is pressed, or
when System, Restore Defaults, All Modes is pressed.
