Commands and Responses
Commands
are messages that the controller sends to the instrument. They oper-
ate the instrument functions and request information. The commands are divided
into types based on two criteria:
●
On the basis of the effect that they have on the instrument
–
Setting commands
control instrument settings, such as resetting the
instrument, or entering setting values.
–
Query commands
make output data for the remote control, for example
for identifying the instrument or for querying a setting's value. Queries
have a question mark
?
at the end of the setting command.
●
On the basis of how they are defined in the IEEE 488.2 and SCPI standards:
–
Common commands
are precisely defined with regard to their function
and syntax in the IEEE 488.2 standard. These commands are identical for
all instruments, and they refer to functions such as the management of the
standardized status register, resetting and self-testing.
–
Instrument-dependent commands
are for functions that depend on the
characteristics of the specific instrument, such as frequency setting. Many
of these commands have also been standardized by the SCPI Consortium.
Such commands are labeled "SCPI compliant" in the command reference.
Commands without the SCPI label are instrument-dependent, however,
their syntax follows the SCPI rules, as allowed by the standard.
Responses
are messages that the instrument transmits to the controller after a
query command. Responses contain measurement results, instrument settings or
status information on the instrument.

LAN Interface
The Inline Calibration Controller R&S
ZN-Z30 is equipped with a LAN interface to
enable integration into a local area network (LAN). This interface consists of a
connector, a network card, and protocols.
For remote control via the network, the controller and the R&S
ZN-Z30 must be
connected via the LAN interface to a common network that uses the TCP/IP net-
work protocol. They are connected using commercially available RJ-45 cables.
