SCPI Commands
The instrument complies with the rules and conventions of the present 
version of SCPI (Standard Commands for Programmable Instruments). 
SCPI Language Conventions
Throughout this guide, the following conventions are used for SCPI 
command syntax for remote interface programming:
• Braces ( { } ) enclose the parameter choices for a given command 
string. The braces are not sent with the command string.
• A vertical bar ( > ) separates multiple parameter choices for a given 
command string.
• Triangle brackets ( < > ) indicate that you must specify a value for the 
enclosed parameter. The brackets are not sent with the command string.
• Some parameters are enclosed in square brackets ( [ ] ). This indicates 
that the parameter is optional and can be omitted. The brackets are not 
sent with the command string. If you do not specify a value for an 
optional parameter, the instrument chooses a default value.
SCPI Language Version
You can determine the SCPI version with which the multimeter is in 
compliance by sending a command from the remote interface.
• You can query the SCPI version from the remote interface only.
•
Remote Interface Operation:  The following command queries the 
multimeter’s SCPI language version:
SYSTem:VERSion?
• The SCPI version is returned in the form “YYYY.V”, where “YYYY” 
represents the year of the version, and “V” represents a version number 
for that year (for example, 1994.0).
