Acquisition
Digital (Mixed Signal)
The
digital leadset
(standard with -MS model oscilloscopes) inputs up-to-16 lines of digital data.
Leads are organized into two banks of eight leads each, and you assign each bank a standard Logic
Family or a custom Threshold to define the digital logic of the signal.
There are four set up dialogs for each of four possible digital groups, which correspond to buses:
Digital1 to Digital4. You choose which lines from among the 16 make up each digital group, what they
are named, and how the group appears on the display. Initially, logical lines are numbered the same
as the physical lead they represent, although any line number can be re-assigned to any lead.
Digital Traces
When a digital group is enabled, digital Line traces show which lines are high, low, or transitioning
relative to the threshold. You can also view a digital Bus trace that collapses all the lines in a group
into their Hex values.
Four digital traces displayed with a Vertical Position +4.0 (top of grid) and a Group Height 4.0 (divisions).
Activity Indicators
Activity indicators at the bottom of the Digitalx dialogs show which lines are High (up arrow), Low
(down arrow), or Transitioning (up an down arrows) relative to the Logic Threshold value. They provide
a quick view of which lines are active and of interest to display on screen.
