IEEE-488.2 common commands
The IEEE-488.2 standard defines a set of common commands that perform
functions like reset, self-test, and status operations. Common commands always
begin with an asterisk ( * ), are four to five characters in length, and may include
one or more parameters. The command keyword is separated from the first
parameter by a blank space . Use a semicolon ( ; ) to separate multiple commands
as shown below:
SCPI parameter types
The SCPI language defines several different data formats to be used in program
messages and response messages.
Numeric parameters
Commands that require numeric parameters will accept all commonly used
decimal representations of numbers including optional signs, decimal points, and
scientific notation. Special values for numeric parameters like
MINimum
,
MAXimum
,
and
DEFault
are also accepted. You can also send engineering unit suffixes (V, A
or SEC) with numeric parameters. If only specific numeric values are accepted, the
power supply will automatically round the input numeric parameters. The
following command uses a numeric parameter:
Discrete parameters
Discrete parameters are used to program settings that have a limited number of
values (like
BUS
,
IMM
). Query responses will always return the short form in all
upper-case letters. The following command uses discrete parameters:
“*RST; *CLS; *ESE 32; *OPC?”
CURR {<current>|MIN|MAX|UP|DOWN}
TRIG:SOUR {BUS|IMM}
