MAUI Oscilloscopes Remote Control and Automation Manual
Viewing XStreamDSO Objects
The number of different objects in a complete oscilloscope setup is obviously large and changes with the
installation of new firmware and software options. XStreamBrowser helps you quickly find the object path
and valid values corresponding to any instrument control.
The object hierarchy exposed by MAUI instruments is rooted at the Application object. This object is
always named LeCroy.XStreamDSO.
All major instrument subsystems are available from this object, and many of these subsystems
themselves may be brokendown further. As new software options are activated on the oscilloscope,
these subsystems are added to the Application object hierarchy.
Anything exposed by the object hierarchy can be controlled or read back via Automation.
Object Hierarchy
The left-hand pane of the XStreamBrowser window contains an
expandable navigation "tree." The object hierarchy is tiered; for
example, the Acquisition subsystem is comprised of a variety of
objects, each with child objects.
The right-hand pane shows the Control Variables or Properties
related to the object selected from the navigation tree.
Control Variables
The majority of the items you will find as you expand the navigation tree are Control Variables, or CVARs
for short. These are shown as yellow folders in the XStreamBrowser window.
CVARs provide an interface for accessing scope configurations and for executing methods and actions.
When viewed from XStreamBrowser, many CVARs appear to be properties, but are actually objects with
properties such as Name,Value, and Type, to name a few. See Control Variables for a description of CVAR
Types, Properties, and Methods.
