DME1600

Message Overview

The information that is transferred between the controller (PC) and the DME1600 is referred
to as “messages.”
The DME1600 uses the SCPI language for these messages.
The messages that the PC sends to the DME1600 are commands. The messages that the
DME1600 sends to the PC are responses.
Commands are used to execute functions or change settings on the DME1600 or to query the
DME1600’s settings or status. Responses are used to return the DME1600’s settings or sta-
tus.

Command hierarchy

SCPI is an ASCII-based command language that was designed for test and measuring equip-
ment. The command structure is composed of the common roots and nodes that are the
building blocks of the SCPI subsystem. A command consists of a program header, parame-
ters, and punctuation marks.
The following table uses the SENSe subsystem as an example to explain the hierarchy.

A colon (:) separates a higher node from a lower node.

You need to set an appropriate wait time for sending and receiving messages. Communica-
tion errors may occur if a wait time has not been set.
