KXCI CVU commands

There are two command modes used to control the CVU using KXCI: User mode and System
mode. This mimics the paradigm used to control the SMUs in I/V tests.
User mode is analogous to LPTLIB (when running local) in that all of the commands are
processed sequentially, and the user has full control over the execution sequence and flow control.
In this mode, when a measurement is complete, only one point is generated (R + Jx, Cp, Gp, Cs,
Rs, and so on).
System mode is similar to KITE ITMs in that all CVU test parameters are buffered and executed
automatically by the system when the user sends the run command. Full sweeps are executed by
the CVU card itself, and the output sequencing, settling, and sweeping are all handled internally.
The user simply returns the entire buffer of test data.
It is important to note that many of the commands below are valid in both User and System mode.
When in user mode, the command is processed immediately and sent directly to the card. In
system mode, the parameter is buffered in a test object, and does not take effect until the execute
command is sent. At that time, the CVU's firmware acts upon the settings and executes the
desired test sequence.
NOTE
9-96
All of the commands act on the selected card which is set with the :CVU:CHANNEL
command.
