Making a Closed-Loop XY Measurement
There are many parameters that are possible to change when using the Analyzer in
closed-loop operation. Some of these are the same with either closed-loop (Analyzer
drives the internal generator) or open-loop (Analyzer and generator are independent)
operation. Many of the settings presented in the following procedure are already
correctly set as the default settings of the AM700 on power up and will not have to
be changed for most measurements. They are given in this example exercise as a
reminder of the choices that can be made.
