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 and Hysteresis to capture the digital signals.
The Digital set up dialog has four tabs each corresponding to one of four possible digital groups, labeled
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.
Three Digital Line traces and a Bus trace displayed with a Vertical Position of positive 4.0 divisions (top of
grid) and a Group Height 4.0 divisions (half the grid).
Activity Indicators
Activity indicators at the bottom of the Digital<#> 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.
