Dependencies Only available if Option EMC is installed
Preset Set to OFF on Global Settings, Restore Defaults and System, Restore Defaults, All Modes
Range
ALL | NONE
Global Limit Lines (Freq and Amptd)
When this control is set to ALL, the current Mode’s Limit Line is copied into the
Global Limit Lines, and from there to all Modes that support Global settings and use
Global Limit Lines, so you can switch between any of these Modes and the Limit
Lines remain unchanged.
Adjusting the Limit Lines of any Mode that supports Global Settings, while Global
Limit Lines is ALL, modifies the Global Limit Lines.
When Global Limit Lines is set to NONE, the Limit Lines of the current Mode are
unchanged, but now the Limit Lines of each Mode are once again independent.
When Mode Preset is pressed while Global Limit Lines is ALL, Global Limit Lines is
preset to the preset Limit Lines of the current Mode.
This function is reset to NONE when "Restore Defaults" on page 2037 is pressed, or
when System, Restore Defaults, All Modes is pressed.

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.
