Analyze Waveform Data
Searching and Marking Waveforms
You can mark locations of interest in the acquired waveform. These marks help you limit your analysis to particular regions of the
waveform. You can mark areas of the waveform automatically, if they meet some special criteria, or you can manually mark each
item of interest. You can use arrow keys to jump from mark to mark (area of interest to area of interest). You can automatically
search and mark many of the same parameters that you can trigger on.
Search marks provide a way to mark a waveform region for reference. You can set marks automatically with search criteria. You
can search for and mark regions with particular edges, pulse widths, runts, logic states, rise/fall times, setup and hold, and bus
search types.
To manually set and clear (delete) marks:
1. Move (the zoom box) to the area on the
waveform where you want to set (or clear)
a search mark by turning the pan (outer)
knob.
Push the next (
→ ) or previous ( ← ) arrow
button to jump to an existing mark.
2. Push Set/Clear .
If no search mark is at the screen center,
the oscilloscope will add one.
