"SCPI confirmed" in the command reference chapters. Commands without this
SCPI label are device-specific; however, their syntax follows SCPI rules as per-
mitted by the standard.
Instrument responses
Instrument responses (response messages and service requests) are messages the
instrument sends to the controller after a query. They can contain measurement
results, instrument settings and information on the instrument status.
13.1.5 SCPI Command Structure
SCPI commands consist of a header and, in most cases, one or more parameters. 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 (keywords).
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.
13.1.5.1 Syntax for Common Commands
Common (= device-independent) commands consist of a header preceded by an aster-
isk (*), and possibly one or more parameters.
Table 13-3: Examples of common commands
*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.
