Digital Channel Setup in WaveSurfer 3000
Oscilloscopes
TECHNICAL BRIEF
Introduction
Teledyne LeCroy’s WaveSurfer 3000 oscilloscopes provide 16 digital
signal inputs that are easily set up, labeled, and grouped in a myriad of
ways. Taking a little time to customize your setup at the outset of a
debugging session will help to make the debug process quick and
intuitive.
Procedure
For purposes of this demonstration, digital lines D0-D4 of the 16-channel
digital lead set were connected to clock pins of varying speeds. Next,
press the Dig (for Digital) button in the Vertical section of the front panel,
or access the Digital Channels dialog using the Vertical pull-down menu
on the touch screen. Either will activate the digital channels and also open
the Digital Channels dialog (Figure 1).
Figure 1: The Digital Channels dialog box, where users may indicate how
many, and which, of 16 available digital input lines are to be shown on the
display.
Across the bottom center of the Digital Channels dialog are the Line
Activity indicators, which provide a quick means of determining the logical
state of all digital lines at once (Figure 1, again). The oscilloscope need
not be triggered to observe line activity with the indicators. The indicators
return three states: High, Low, and Transitioning.
