3.10.8.3 Global
The controls in this menu apply to all Modes in the instrument.
Some controls (for example, "Global Center Freq" on page 2034) allow you to switch
certain Meas Global parameters to a Mode Global state. These switches apply to all
Modes that support global settings. For example, no matter what Mode you are in
when you set Global Center Freq to ON, it applies to all Modes that support Global
settings.
Other controls (for example, Extend Low Band) are actually set in this menu, but
apply to all Modes.
Global Center Freq
The software maintains a Mode Global value called Global Center Freq.
When Global Center Freq is switched ON, the current Mode’s center frequency is
copied into the Global Center Frequency, and from then on all Modes that support
global settings use the Global Center Frequency, so you can switch between any of
these Modes and the Center Frequency remains unchanged.
Adjusting the Center Frequency of any Mode that supports Global Settings, while
Global Center Freq is ON, modifies the Global Center Freq.
When Global Center Freq is switched OFF, the Center Frequency of the current
Mode is unchanged, but now the Center Frequency of each Mode is once again
independent.
When Mode Preset is pressed while Global Center Freq is ON, the Global Center Freq
is preset to the preset Center Frequency of the current Mode.
