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 as a sequence of ASCII data messages. Examples of a typical Common Command and Subsystem Command are:

OUTPUT 712;"*CLS"

OUTPUT 712;":INP1:COUP AC;IMP 1.0 MOHM"

Subsystem Command Syntax

Figure 3-2 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 .

NOTE: sp = space. ASCII character decimal 32
