MAUI Oscilloscopes Remote Control and Automation Manual
Note: Only a single instance of the XStreamDSO software can run on a system at one time. If the
software is already running when CreateObject is called, a handle to that running instance is
returned. If XStreamDSO is not running, it will be started.
AutoSetup
AutoSetup is an Action that utilizes default Vertical and Timebase settings and a 50% level Edge trigger to
quickly set up an acquisition on the oscilloscope. The first active input channel is used as the triggger
source.
AutoSetup occurs "above" the individual subsystems in the XStreamDSO application hierarchy, at the root
object LeCroy.XStreamDSO. In XStreamBrowser, you will find it in the root folder. Had this command
involved only C1, for example, you would have navigated to Acquisition > C1 and selected it to show the C1
CVARs.
You can see AutoSetup is an Action from the Type column. Most of what occurs at this top level are
Actions.
Right-click on AutoSetup and choose Copy Path.
Go back to the text editor window, and paste the AutoSetup command into your program:
app.AutoSetup
Change Grid Mode
The Grid Mode determines how many grids appear on the oscilloscope display at once. This is one setting
where a change can be perceived without an input signal. Grid Mode affects the oscilloscope display, so it
is found within the Display subsystem.
In XStreamBrowser, expand the Display folder until you see the CVARs in the right-hand window pane.
Navigate to the object GridMode. You can see the valid settings in Range/Helpstring include Auto, Single,
Dual, Quad, etc.
Right-click on GridMode and choose Copy Path. You'll see from the XStreamBrowser window message bar
that the object path is:
app.Display.GridMode
Note that the controls are arranged in a hierarchy, with each level delimited by a decimal point ( . ).
Paste the line into your remote control program, then set the new value of Quattro:
app.Display.GridMode = “Quattro”
Using the app handle, this line of code sets the Grid Mode control of the Display system to the value
“Quattro”.
