SCPI Command Format
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, then 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 Format
SCPI commands control and set instrument specific functions such as setting the
pulse width, delay and period. SCPI commands have a hierarchical struc-ture
composed of functional elements that include a header or keywords sepa-rated
with a colon, data parameters, and terminators. For example:
SCPI Format
:PULSE1:STATE ON<cr><lf>
:PULSe1:WIDTh 0.000120<cr><lf>
:PULSe:POL NORMal<cr><lf>
Any parameter may be queried by sending the command with a question mark
appended. For example:
- QUERY FORMAT
:PULSE1:STATE?<cr><lf>
Will return:
1<cr><lf>
:PULSE1:WIDT?<cr><lf>
Will return:
0.000120000<cr><lf>
:PULSE1:POL?<cr><lf>
Will return:
NORM<cr><lf>
SCPI Keyword Separator
A colon (:) must always separate one keyword from the next lower-level
key-word. A space must be used to separate the keyword header from the first
parameter. If more than one parameter is used, you must separate subsequent
parameters with a comma.
