6.3 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.
6.3.1 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
register.
*IDN? IDENTIFICATION QUERY Queries the instrument identification
string.
