Using SCPI Commands
TM-XDOP-01XN C–5
Using SCPI Commands
Throughout these commands, the optional command [<channel>] is available
for the units equipped with the optional CANbus interface card.
This manual shows SCPI commands in the following format:
CALibration:CURRent:LEVel {<current>|MIN|MAX}
The command is expressed as a mixture of upper- and lowercase letters. The
uppercase letters suggest how the command can be abbreviated into a short form.
SCPI commands can be sent in long or short forms. The short form is better for
data entry. The long form is better for readability.
Command strings are not case sensitive: CURR, Curr, and curr are all acceptable
abbreviations for CURRent. As for the long form, CURRENT, Current, and
current are all acceptable.
The command strings include punctuation. While some punctuation is sent with
the string, other markings are used to identify different elements of the command
syntax and are not sent with the string.
The following punctuation is sent with the command string:
• Colons (:) separate command keywords from lower-level keywords.
For example,
CAL:CURR:STAT.
• Blank spaces separate command keywords from parameter values.
For example,
CURR 0.1.
• Commas separate parameters from each other when more than one parameter
is sent in the same string. For example,
CAL:STAT OFF,”1234.”
• Semicolons (;) separate multiple commands from the same subsystem. This
allows for greater efficiency. For example:
CAL:CURR:LEV MIN;VOLT:LEV MIN
is the same as typing:
CAL:CURR:LEV MIN
CAL:VOLT:LEV MIN
• Colons and semicolons can be used together to link commands from different
subsystems. For example:
CAL:CURR:LEV MIN;:MEAS:CURR?
