Introduction to Programming
The SCPI commands used to program the digitizer are separated into two
groups: common commands and subsystem commands. Common
commands begin with an asterisk, and include commands such as *RST,
*CLS, *OPC?. Chapter 4 contains a complete listing of the digitizer’s
common commands.
Subsystem commands are those commands which configure the digitizer.
Each subsystem is a set of commands that roughly corresponds to a
functional block inside the digitizer. Figure 1-4 identifies the SCPI
subsystems used with the digitizer.
