Structure and syntax of the instrument messages are described in Chapter 7, "Com-
mand reference", on page 840. The chapter also provides a detailed description of all
messages implemented by the analyzer.
12.3.4 Handler I/O (universal interface)
Option R&S ZN-B14 / R&S ZNBT-Z14
A network analyzer which is equipped with a Handler I/O (Universal Interface) option,
can interact with an external part handler. The digital control signals on the interface
connector indicate the possible start and the end of a measurement, as well as a
global limit check result. Typically, the handler will insert the device to be tested into a
test fixture, provide a trigger pulse to initiate the measurement, remove and replace the
device after the measurement is complete and sort it into pass/fail bins. A sample flow
diagram for this process is shown below.
