Meas Setup Summary Table
Lets you view and access many of the parameters in the Meas Setup menus on one
screen.
Auto Couple
Immediately puts all Auto/Man functions into Auto. Auto Couple is confined to the
current measurement only. It does not affect other measurements in the Mode.
In the Auto state, Auto/Man functions are said to be “coupled”, meaning their values
change as you make changes to other values in the measurement. This helps ensure
accurate measurements and optimum dynamic range. Auto Couple is an immediate
action function, and when it is executed, all the Auto/Man controls for the current
measurement are set to Auto, and all measurement settings coupled to the
Auto/Man parameters are automatically set to their optimal values.
For further details of measurement-specific settings (if any), see "Measurement-
Specific Details" on page 645 below.

Notes
:COUP:NONE puts all Auto/Man parameters in manual mode, decoupling all the coupled instrument
parameters. It is retained for backwards compatibility and is not recommended for making
measurements or new designs
All Auto/Man parameter couplings in the measurement are set to Auto. This
includes couplings that may be unavailable or grayed-out due to the current state.
For example, in the Swept SA measurement, there is no Auto/Man coupling for RBW
