Keithley 7001 User Manual

IEEE-488 Reference

5.9
Programming syntax
The following programming syntax information covers both common commands and SCPI
commands. For information not covered here, refer to the documentation for the IEEE-488.2
standard and SCPI.
Command words
One or more command words make up the program message that is sent to the computer to per-
form one or more operations.
1. Commands and command parameters: Both common commands and SCPI commands
may or may not use a parameter. Examples:
*SAV 0 Parameter (0) required.
*RST No parameter used with this command.
:INITiate:CONTinuous <b> Parameter (<b>) required.
:SYSTem:PRESet No parameter used with this command.
Note that there must be at least one space between the command word and the parameter.
Brackets [ ]: Throughout this manual, you will find command words that are enclosed in
brackets ([]). These brackets are simply used to denote an optional command word that
does not need to be included in the program message. For example:
:INITiate[:IMMediate]
The 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. Do not include the brack-
ets when using an optional command word.
Parameter types:
Some of the more common parameter types used in this manual are ex-
plained as follows:
<b> Boolean: Used to enable or disable an instrument operation. In general, 0 or
OFF disables the operation, and 1 or ON enables the operation. Specifically, a
Boolean parameter is processed as follows:
