sensitivity and IF overloads.

Dependencies The IF Gain controls (FFT IF Gain and Swept IF Gain) have no effect when the U7227A USB Preamp-
lifier is connected. This is not annotated or reflected on any control; there are no controls grayed out
nor any SCPI locked out. The instrument simply behaves as though both FFT IF Gain and Swept IF
Gain are set to Low regardless of the setting on the controls
This control is not available in VXT model M9421A, EXM, or UXM

3.13.8.4 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.
