Discover: Industry Exclusive Zone Touch Trigger Makes Triggering Simple
An uncompromised update rate allows you to see an anomaly, but to continue the
debug process you have to isolate it. Setting up a trigger has been a challenge since
oscilloscopes introduced a triggered waveform. While oscilloscopes have added more
and more triggering capability over the years, setting up triggers has remained complex
at best and impossible at worst.
Zone touch trigger eliminates the complexity of setting up advanced triggers. Now, if you
can see the event on the display of the oscilloscope, you can trigger on it just by drawing
a box on the signal you want to isolate.
See how easy Zone touch triggering can be with these examples.
Steps to isolate a non-monotonic edge:
3000T X-Series:
–– Draw box on non-monotonic edge
–– Select “must intersect”
In some cases you may have to select the appropriate source if
it wasn’t already selected.
Traditional Scopes with Advanced Triggers
(assuming the update rate is fast enough to see
what you want to trigger on):
1. Determine what trigger makes the most sense for the
signal you are trying to isolate. In this case, we’ll try a
rise-time trigger first.
2. Select cursors
3. Move cursor a to 10% level
4. Move cursor b to 90% level on the non-monotonic
edge
5. Obtain the delta time (rise time) between the cursors
6. Select trigger menu
7. Press trigger type
8. Select Rise/Fall time Trigger
9. Select your source
10. Select your slope
11. Select when you want it to trigger – is it less than,
greater than, equal to, not equal to. We’ll select greater
than.
12. Dial in the “greater than” setting to the measured rise
time
13. Adjust your low threshold to the 10% level
14. Adjust your high threshold to the 90% level
