SCPI Commands HMC8012
1.4.2 SCPI Command Structure
SCPI commands consist of a so-called header and, in most cases, one or more parameters. The header and the para-
meters 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 commands). Common and device-speci-
S C P I P r o g r a m m e r s M a n u a l
fic commands differ in their syntax.
Syntax for Common Commands
S C P I P r o g r a m m e r s M a n u a l
S C P I P r o g r a m m e r s M a n u a l
Common (= device-independent) commands consist of a header preceded by an asterisk (*) and possibly one or more
parameters.
Examples:
*RST
*ESE
*ESR?
*IDN?
Table 1.4: Examples of Common Commands
Syntax for Device-Specific Commands
Not all commands used in the following examples are necessarily implemented in the instrument.
For demonstration purposes only, assume the existence of the following commands for this section:
- CALCulate:FUNCtion {NULL | DB | DBM | AVERage | LIMit}
:ACQuire
- CALCulate:FUNCtion?
- CALCulate[:STATe] {OFF | ON}
:CHAN1OFFSet
- CALCulate[:STATe]?
Long and short form
The mnemonics feature a long form and a short form. The short form is marked by upper case letters, the long form
corresponds to the complete word. Either the short form or the long form can be entered; other abbreviations are not
permitted.
Example:
CALCulate:FUNCtion NULL is equivalent to CALC:FUNC NULL
Case-insensitivity
Upper case and lower case notation only serves to distinguish the two forms in the manual, the instrument
itself is case-insensitive.
