R&S FSP Remote Control – Description of Commands
Notation
6.6 Operating Manual 1164.4556.12 - 06
Upper/lower case
notation Upper/lower case letters are used to mark the long or short form of the key words
of a command in the description (see chapter
“Remote Control – Basics” ). The
instrument itself does not distinguish between upper and lower case letters.
Special characters |
A selection of key words with an identical effect exists for several commands.
These key words are indicated in the same line; they are separated by a vertical
stroke. Only one of these key words needs to be included in the header of the
command. The effect of the command is independent of which of the key words is
used.
Example:
SENSe:FREQuency:CW|:FIXed
The two following commands with identical meaning can be created. They set
the frequency of the fixed frequency signal to 1 kHz:
SENSe:FREQuency:CW 1E3
=
SENSe:FREQuency:FIXed 1E3
A vertical stroke in parameter indications marks alternative possibilities in the
sense of "or". The effect of the command is different, depending on which
parameter is used.
Example: Selection of the parameters for the command
DISPlay:FORMat FULL | SPLit
If parameter FULL is selected, full screen is displayed, in the case of SPLit, split
screen is displayed.
[ ]
Key words in square brackets can be omitted when composing the header (cf.
chapter
“Remote Control – Basics” , section “Optional key words” on page 5.11 ).
The full command length must be accepted by the instrument for reasons of com-
patibility with the SCPI standards.
Parameters in square brackets can be incorporated optionally in the command or
omitted as well.
{ }
Parameters in braces can be incorporated optionally in the command, either not at
all, once or several times.
Description of
parameters Due to the standardization, the parameter section of SCPI commands consists
always of the same syntactical elements. SCPI has therefore specified a series of
definitions, which are used in the tables of commands. In the tables, these estab-
lished definitions are indicated in angled brackets (< to >) and will be briefly
explained in the following (see also chapter
“Remote Control – Basics” , section
“Parameters” on page 5.13 ).
<Boolean> This key word refers to parameters which can adopt two states, "on" and "off". The
"off" state may either be indicated by the key word
OFF or by the numeric value 0,
the "on" state is indicated by ON or any numeric value other than zero. Parameter
queries are always returned the numeric value 0 or 1.
