16.1.4 SCPI Command Structure

SCPI commands consist of a so-called header and, in most cases, one or more param-

eters. The header and the parameters are separated by a "white space" (ASCII code 0

to 9, 11 to 32 decimal, e.g. blank). The headers may consist of several mnemonics (key-

words). Queries are formed by appending a question mark directly to the header.

The commands can be either device-specific or device-independent (common com-

mands). Common and device-specific commands differ in their syntax.

16.1.4.1 Syntax for Common Commands

Common (=device-independent) commands consist of a header preceded by an asterisk

(*) and possibly one or more parameters.

Examples:

*RST RESET Resets the instrument.

*ESE EVENT STATUS ENABLE Sets the bits of the event status enable

registers.

*ESR? EVENT STATUS QUERY Queries the contents of the event status

*IDN? IDENTIFICATION QUERY Queries the instrument identification

string.
