Numeric suffixes
Symbols in angular brackets (<ch>, <i>, <n>,...) denote numeric suffixes. Numeric suf-
fixes have to be replaced by integer numbers to distinguish various items of the same
type. The R&S CMW500 provides numeric suffixes for firmware application instances,
signal sources etc. If unspecified, a numeric suffix is replaced by 1.
Example:
SOURce:GPRF:GENerator:DTONe:OFRequency2 1MHz
This command specifies an offset frequency for the second (Source 2) component of the
dual-tone GPRF generator signal.
GENerator
(without suffix or with suffix 1) denotes
the first instance of the GPRF generator.
Information in the command reference sections
All commands are described according to the same scheme. The following information
is provided:
●
Complete command syntax and parameter list
●
Description of the command and its relationship with other commands
●
List and description of the parameters with their numerical ranges, default values and
default units
●
Supported command types (setting command, query)
●
Program example (optional)
The commands are arranged according to the order of parameters in the corresponding
dialogs of the Graphical User Interface. This means that related commands are generally
grouped together. Groups of commands with similar function (e.g. several
READ...?
and
FETCh...?
queries for a single measurement application) are listed with a common
command description.

Structure of a Command Line
A command line may consist of one or several commands. It is terminated by a
<New
Line>
, a
<New Line>
with EOI or an EOI together with the last data byte. Some pro-
gramming languages automatically produce an EOI together with the last data byte.
Several commands in a command line must be separated by a semicolon ";". If the next
command belongs to a different command system, the semicolon is followed by a colon.
Example
:
ROUTe:GPRF:GENerator:SCENario:SALone RF1C; :SOURce:GPRF:
GENerator:RFSettings:FREQuency 1GHZ
This command line contains two commands. The first command belongs to the
ROUTe
system and selects the output connector for the GPRF generator. The second command
belongs to the
SOURce
system and defines the frequency of the GPRF generator signal.
If the successive commands belong to the same system, having one or several levels in
common, the command line can be abbreviated. To this end, the second command after
