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.
A.1
Syntax for Common Commands

isk (*), and possibly one or more parameters.
