8 Remote Commands for the I/Q Analyzer
The following commands are specific to performing measurements in the I/Q Analyzer
application in a remote environment. The R&S FSWP must already be set up for
remote operation in a network as described in the R&S FSWP user manual.

8.1 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.
Only the most important characteristics that you need to know when working with SCPI
commands are described here. For a more complete description, refer to the User
Manual of the R&S FSWP.
