Command Syntax
Command Syntax
Following the heading for each programming command entry is a syntax statement
showing the proper syntax for the command. An example syntax statement is shown here:
POWer[:LEVel] MAXimum|MIN
Syntax statements read from left to right. In this example, the :LEVel portion of the
statement immediately follows the POWer portion of the statement with no separating
space. A separating space is legal only between the command and its argument. In this
example, the portion following the [:LEVel] portion of the statement is the argument.
Additional conventions used in the syntax statements are defined as follows:
• Italics are used to symbolize a program code parameter or query response.
• := means “is defined as.”
• | (vertical bar) indicates a choice of one element from a list. For example, <A>|<B>
indicates <A> or <B> but not both.
• [] (square brackets) indicate that the enclosed items are optional.
• Upper-case lettering indicates that the upper-case portion of the command is the
minimum required for the command. For example, in the command FREQuency, FREQ
is the minimum requirement.
• Lower-case lettering indicates that the lower-case portion of the command is optional; it
can either be included with the upper-case portion of the command or omitted. For
example, in the command FREQuency, either FREQ, or FREQUENCY is correct.
• ? after a subsystem command indicates that the command is a query.
