SCPI Command Keywords

The commands are shown as a mixture of upper and lower case letters.  The upper case letters
indicate the abbreviated spelling for the command.  You may send either the abbreviated version
or the entire keyword.  Upper and/or lower case characters are acceptable.

For example:  If the command keyword is given as POLarity, the POL and POLARITY are
both acceptable forms; truncated forms such as POLAR will generate an error; polarity, pol,
and PolAriTy are all acceptable as the pulse generator is not case sensitive.

SCPI Command and Query Format

SCPI commands control and set instrument specific functions such as setting the pulsewidth,
delay and period.  SCPI commands have a hierarchical structure composed of functional
elements that include a header or keywords separated with a colon, data parameters and
terminators.

:PULSE1:STATE ON

<cr> <lf>

:PULSe1:WIDth 0.000120

<cr> <lf>

:PULSe:POL NORMal

<cr> <lf>

A colon always separates one keyword from the next lower-level keyword.  A space must be
used to separate the keyword header from the first parameter.  If more than one parameter is
used, you must separate adjacent parameters with a comma.

Any parameter may be queried by sending the command with a question mark appended.

For example:

:PULSE1:STATE?

Will return:

1 <cr> <lf>

:PULSE1:WIDT? <cr> <lf>

Will return:

0.000120000 <cr> <lf>

:PULSE1:POL? <cr> <lf>

Will return:

NORM <cr> <lf>
