Command Set Organization

The command set is divided into common commands, root level commands and

sets of subsystem commands. Each of the groups of commands is described in

the Programmer’s Reference, which is supplied as an online help file for

Microsoft Windows. See chapter 7, “Installing and Using the Programmer’s

Reference” for information on installing and using the help file.

The commands shown use upper and lowercase letters. As an example,

AUToscale indicates that the entire command name is AUTOSCALE. To speed

up the transfer, the short form AUT is also accepted by the oscilloscope. Each

command listing contains a description of the command and its arguments and

command syntax. Some commands have a programming example.

The subsystems are listed below:
