Digital (Mixed Signal)
The digital leadset (delivered with the WS3K-MSO option) 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.
The Digital set up dialog has two tabs each corresponding to one of two possible digital groups, labeled
Digital1 to Digital2, which correspond to buses. 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.
Group of four traces displayed with a Vertical Position of positive 4.0 (top of grid) and a Group Height 4.0 (half the grid).
