9 Remote Commands to Perform Measure-
ments with I/Q Data
The following commands are specific to performing measurements in the I/Q Analyzer
application in a remote environment. The R&S
ZNL must already be set up for remote
operation in a network as described in the base unit manual.
Note that basic tasks that are also performed in the base unit in the same way are not
described here. For a description of such tasks, see the R&S
ZNL User Manual.
In particular, this includes:
●
Basic instrument configuration, e.g. checking the system configuration, customizing
the screen layout, or configuring networks and remote operation
●
Using the common status registers

9.1 Introduction
Commands are program messages that a controller (e.g. a PC) sends to the instru-
ment or software. They operate its functions ('setting commands' or 'events') and
request information ('query commands'). Some commands can only be used in one
way, others work in two ways (setting and query). If not indicated otherwise, the com-
mands can be used for settings and queries.
The syntax of a SCPI command consists of a header and, in most cases, one or more
parameters. To use a command as a query, you have to append a question mark after
the last header element, even if the command contains a parameter.
A header contains one or more keywords, separated by a colon. Header and parame-
ters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank).
If there is more than one parameter for a command, these are separated by a comma
from one another.
