Elements of SCPI Commands

Elements of SCPI Commands
A program command or query is composed of functional elements that
include a header (or keywords with colon separators), program data, and
terminators. These elements are sent to the Counter over the
HP-IB or the RS-232 interface as a sequence of ASCII data messages.
Examples of a typical Common Command and Subsystem Command are:
OUTPUT 712;" CLS"
*
OUTPUT 712;":DISP:ENAB ON;:FREQ:RES 1KHz"
Subsystem Command Syntax
Figure 3-6 shows the simplified syntax of a Subsystem Command. You
must use a space (SP) between the last command mnemonic and the first
parameter in a Subsystem Command. Note that if you send more than one
parameter with a single command, you must separate adjacent
parameters with a comma.
