SCPI commands
The U3606A complies with the syntax rules and conventions of SCPI 
(Standard Commands for Programmable Instruments).
SCPI language version
You can determine the SCPI language version of the instrument by sending 
the  SYSTem:VERSion? command from the remote interface.
• You can query the SCPI version from the remote interface only.
• 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).
SCPI query timeout
The SCPI query timeout represents the absolute time period (in 
milliseconds) that the resource waits for the device to respond before this 
operation returns an error (default value is 5000 milliseconds).
Some measurements may result in a delayed response time in the U3606A 
Multimeter|DC Power Supply. It is recommended that you increase the 
SCPI query timeout to 15000 milliseconds or longer to avoid SCPI query 
timeout errors.
Remote programming using SCPI commands
During remote programming, various SCPI commands are stringed together 
in a single programming module. As the programming module executes 
each SCPI command sequentially, a 1 millisecond interval between each 
subsequent SCPI command is recommended to allow the U3606A 
Multimeter|DC Power Supply sufficient command processing time.
For a complete discussion of all the U3606A SCPI syntax available, refer to 
the U3606A Programmer’s Reference. This document is provided on the 
U3606A Product Reference CD-ROM that came with your instrument.
