Commands and command parameters
Common commands and SCPI commands may or may not use a parameter. The
following are some examples:
*SAV <NRf> Parameter (NRf) required
*RST No parameter used
:CALCulate1:STATe <b> Parameter <b> required
:SYSTem:PRESet No parameter used
NOTE At least one space between the command word and the parameter is
required.
Brackets [ ] — Some command words are enclosed in brackets ([ ]). These brack-
ets are used to denote an optional command word that does not need to be
included in the program message. For example:
:INITiate[:IMMediate]
These brackets indicate that :IMMediate is implied (optional) and does not have to
be used. Thus, the above command can be sent in one of two ways:
:INITiate
or
:INITiate:IMMediate
Notice that the optional command is used without the brackets. When using
optional command words in your program, do not include the brackets.
Parameter types — The following are some of the more common parameter
types:
<b> Boolean
— Used to enable or disable an instrument operation. 0
or OFF disables the operation, and 1 or ON enables the operation.
Example:
:CALCulate1:STATe ONEnable Calc 1 math expression
<name> Name parameter
— Select a parameter name from a listed group.
Example:
<name>= NEVer
= NEXt
:TRACe:FEED:CONTrol NEXt
<NRf> Numeric representation format
— This parameter is a number that
can be expressed as an integer (e.g., 8), a real number (e.g.,
23.6), or an exponent (2.3E6). Example:
:SYSTem:KEY 11Press EXIT key from over the bus
