Steps to trigger on a runt signal:
3000T X-Series:
1. Draw box on the runt
2. Select “must intersect”
3. Draw a second box if needed to further isolate the runt
from other runts
4. Select “must intersect” or “must not 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 use a
runt trigger first.
2. Select trigger menu
3. Press trigger type
4. Select runt Trigger
5. Select your source
6. Select the runt’s polarity
7. Adjust your low threshold to below the runt
8. Adjust your high threshold to above the runt
9. Select when you’ll trigger – in this case, we want to
trigger on the exact pulse width of the runt
10. Select cursors
11. Move cursor a to the rising edge of the pulse at the
50% mark
12. Move cursor b to the falling edge of the pulse at the
50% mark
13. Obtain the delta time (pulse width) between the
cursors
14. Adjust the runt width to be equal to the pulse width
that was measured
