Overview of Messages

The information that is exchanged between the controller (computer) and the device (KFM2005/KFM2030) is called a message.

The KFM2005/KFM2030 uses the SCPI language for the messages.

There are two types of messages, commands that are sent from the computer to the KFM2005/KFM2030 and responses that are sent from the KFM2005/KFM2030 to the computer.

Command hierarchy

SCPI commands are ASCII-based commands designed for test and measurement devices. The command hierarchy is structured around the common root or node, which is the construction block of the SCPI sub system. A command consists of a program header, parameters, and punctuations.

The hierarchy is explained using the SOURce subsystem as an example.

 

Program header Parameter Hierarchy of node
SOUR:   Roote node
  FREQ Second level
  :LIM Third level
  :UPP <numeric> Fourth level
:LOW <bool> Fourth level
VOLT Second level
  :RANGE Third level
  :UPP <numeric> Fourth level
    :AUTO <bool> Fourth level

 

A higher node is separated from a lower node using a colon (:).
