SCPI Command Reference

Using SCPI Commands

This Manual shows SCPI commands in the following format:

CALibration:CURRent:LEVel {<current>MINMAX}

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. It is not possible to write for example, CALibrat:CURR:LEV because the eXGa first node does not explicitly match the short or long form of the calibration node.

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?

The short form is made up of 3 or 4 letters. There can only be a absolute short or long form. For example, it is not possible to write CALibrat:CURR:LEV because the eXGa the first node does not match explicitly the short or long form of the calibration node.
