3 VMA Mode
3.4 IQ Waveform Measurement
Any Auto/Man selection specific (local) to the other measurements in the current
Mode are not affected by Auto Couple. Any functions that are not coupled with other
instrument parameters, such as ranging or leveling variables, such as AutoRange or
AutoScale, are not affected.
Executing Auto Couple generates the informational message, "All Auto/Man
functions have been set to Auto".
Each parameter, upon being set to Auto, selects and sets the appropriate auto-
coupled value based on that parameter’s coupling rules. The Dependency Resolver
orchestrates the couplings for parameters that depend on one or more other
parameters. The coupling and dependency rules for each parameter are defined in
the section describing that parameter.
Executing Auto Coupledoes not affect markers, marker functions, trace or display
attributes, or any other instrument setting other than those specifically mentioned
above.
