User Manual 1177.5862.02 ─ 09
The syntax of a SCPI command consists of a header and, usually, one or more param-
eters. 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, they 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.

Conventions used in descriptions
The following conventions are used in the remote command descriptions:
●
Command usage
If not specified otherwise, commands can be used both for setting and for querying
parameters.
If a command can be used for setting or querying only, or if it initiates an event, the
usage is stated explicitly.
●
Parameter usage
If not specified otherwise, a parameter can be used to set a value and it is the
result of a query.
Parameters required only for setting are indicated as
Setting parameters
.
Parameters required only to refine a query are indicated as
Query parameters
.
Parameters that are only returned as the result of a query are indicated as
Return
values
.
●
Conformity
Commands that are taken from the SCPI standard are indicated as
SCPI con-
firmed
. All commands used by the R&S
FSWP follow the SCPI syntax rules.
●
Asynchronous commands
A command which does not automatically finish executing before the next com-
mand starts executing (overlapping command) is indicated as an
Asynchronous
command
.
●
Reset values (*RST)
Default parameter values that are used directly after resetting the instrument (
*RST
command) are indicated as
*RST
values, if available.
●
Default unit
The default unit is used for numeric values if no other unit is provided with the
parameter.
●
Manual operation
