Structure and syntax of the instrument messages are described in Chapter 8, "Com-

mand Reference", on page 776. The chapter also provides a detailed description of all

messages implemented by the analyzer.

11.3.4 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.
