Command Syntax
Abbreviating Commands,
Queries, and Parameters
Abbreviate most SCPI commands, queries, and parameters to an accepted short
form. This manual shows these short forms as a combination of upper and lower
case letters. The upper case letters indicate the accepted short form of a
command. As shown in the following figure, create a short form by using only
the upper case letters. The accepted short form and the long form are equivalent
and request the same action of the instrument.
Figure 2: Example of abbreviating a command
NOTE:
The numeric suffix of a command or query may be included in either the
long form or short form; the instrument will default to "1" if no suffix is used.
Chaining Commands and
Queries
Chain several commands or queries together into a single message. To create a
chained message, first create a command or query, add a semicolon (;), and then
add more commands or queries and semicolons until the message is complete.
If the command following a semicolon is a root node, precede it with a colon
(:).The single chained message should end in a command or query, not a
semicolon. Responses to any queries in your message are separated by
semicolons.
If a command or query has the same root and lower-level nodes as the previous
command or query, you can omit these nodes.
Unit and SI Prefix
If the decimal numeric argument refers to amplitude, frequency, or time, express
it using SI units instead of using the scaled explicit point input value format
<NR3>. (SI units are units that conform to the Systeme International d'Unites
standard.) For example, use the input format 200 mV or 1.0 MHz instead of
200.0E-3 or 1.0E+6, respectively, to specify voltage or frequency.
