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.
Page 558: Syntax For Common Commands
® Annex R&S SGT100A Remote Control Basics 15.1.3.1 Syntax for Common Commands Common (=device-independent) commands consist of a header preceded by an aster- isk (*) 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.
Page 559 ® Annex R&S SGT100A Remote Control Basics Example: HCOPy:DEVice:COLor ON is equivalent to HCOP:DEV:COL ON. Case-insensitivity Upper case and lower case notation only serves to distinguish the two forms in the manual, the instrument itself is case-insensitive. Numeric suffixes If a command can be applied to multiple instances of an object, e.g. specific channels or sources, the required instances can be specified by a suffix added to the command.
Page 560 ® Annex R&S SGT100A Remote Control Basics Optional mnemonics with numeric suffixes Do not omit an optional mnemonic if it includes a numeric suffix that is relevant for the effect of the command. Example: Definition:DISPlay[:WINDow<1...4>]:MAXimize <Boolean> Command: DISP:MAX ON refers to window 1.
