Controlling the Source Remotely

CD/PMD Analyzer Source 33

Command Structure

The GPIB and RS-232 commands follow the guidelines determined by the

Standard Commands for Programmable Instruments (SCPI) consortium.

For example, the following command syntax is used to activate or

deactivate the source.

SOUR:POW[:STAT]<wsp><Boolean>

³ SOUR, POW and STAT are keywords that define the function of the

command.

³ [ ] indicates that a keyword or parameter is optional.

³ <wsp> indicates that a space is required ("wsp" stands for "white

space").

³ <Boolean> indicates the command parameter.

³ Keywords must be separated by a colon.

To enter commands or queries you must use either the full word for the

command, or the three- or four-letter shortcut. Commands are not

case-sensitive, however spelling errors will cancel the command or query.

The command or query can be written using only shortcuts, only full

words, or a combination of both.

Other command syntax elements are:

³ The comma, which is used to separate values in a command or query.

³ The semi-colon, which is used to separate commands or queries,

when you send more than one at a time

Note: It is recommended that you retrieve the response immediately after

each query.
