Overview
The E5071C macro function (E5071C VBA) can be used not only to
automate measurements but also to control external measurement
instruments connected via USB/GPIB interface by acting as a self-
contained system controller (see An Overview of a Control System Based
on the Macro Function).
The E5071C macro function (E5071C VBA) performs communications via
the COM interface when controlling the E5071C itself, but it communicates
via VISA (Virtual Instrument Software Architecture) when controlling
external measurement instruments.
