Command Notation

The following notation is used in the commands:
< > Angular brackets enclose words that are used as placeholders, of

which there are two types: the header path and the data parameter
of a command.

: = A colon followed by an equals sign separates a placeholder from

the description of the type and range of values that may be used in
a command instead of the placeholder.

{} Braces enclose a list of choices, one of which one must be made.
[ ] Square brackets enclose optional items.
… An ellipsis indicates that the items both to its left and right may be

repeated a number of times.

As an example, consider the syntax notation for the command to set the vertical input sensitivity:

:VOLT_DIV
: = {C1, C2, C3, C4}
: = 2 mV to 5 V

The first line shows the formal appearance of the command, with denoting the
placeholder for the header path and the placeholder for the data parameter specifying
the desired vertical gain value. The second line indicates that one of four channels must be
chosen for the header path. And the third explains that the actual vertical gain can be set to any
value between 2 mV and 5 V.
