Individual description
The individual description contains the complete notation of
the command. An example for each command, the *RST
value and the SCPI information are included as well.
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
Section 3.5.2). 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 keywords are indicated in
the same line; they are separated by a vertical stroke.
Only one of these keywords needs to be included in the
header of the command. The effect of the command is
independent of which of the keywords 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 1kHz:
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. Section 3.5.2, Optional
Keywords). The full command length must be accepted by
the instrument for reasons of compatibility 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 standardisation, 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 established definitions are indicated in
angled brackets (<...>) and will be briefly explained in the
following (see also Section 3.5.5, "Parameters").
<Boolean>
This keyword refers to parameters which can adopt two
states, "on" and "off". The "off" state may either be
indicated by the keyword OFF or by the numeric value 0,
