Syntax Conventions
The format used to show commands is illustrated below:
VOLTage:DC:RANGe {<range>|MIN|MAX|DEF}
The command syntax shows most commands (and some parameters) as
a mixture of upper- and lower-case letters. The upper-case letters indicate the
abbreviated spelling for the command. For shorter program lines, you can send
the abbreviated form. For better program readability, you can send the long
form.
For example, in the above syntax statement, VOLT and VOLTAGE are both
acceptable forms. You can use upper- or lower-case letters. Therefore,
VOLTAGE, volt, and Volt are all acceptable. Other forms, such as VOL and
VOLTAG, are not valid and will generate an error.
Braces ( { } ) enclose the parameter choices for a given command string.
The braces are not sent with the command string.
A vertical bar ( | ) separates multiple parameter choices for a given
command string. For example, {<range>|MIN|MAX|DEF} in the above
command indicates that you can specify a numeric range parameter, or
"MIN", "MAX", or "DEF". The bar is not sent with the command string.
Triangle brackets ( < > ) indicate that you must specify a value for the
enclosed parameter. For example, the above syntax statement shows the
<range> parameter enclosed in triangle brackets. The brackets are not sent
with the command string. You must specify a value for the parameter (for
example "VOLT:DC:RANG 10") unless you select one of the other options
shown in the syntax (for example "VOLT:DC:RANG MIN").
Some parameters are enclosed in square brackets ( [ ] ). This indicates that
the parameter is optional and can be omitted. The brackets are not sent with
the command string. If you do not specify a value for an optional parameter,
the instrument chooses a default value.
