Short Name: Runt Polarity
Property of niScope
Specifies the polarity of pulses that trigger the oscilloscope for runt triggering.
This property determines how the oscilloscope triggers relative to the runt thresholds you set.
When set to Positive, the oscilloscope triggers when the following conditions are met:
- The leading edge of a pulse crosses the Runt Low Threshold in a positive direction;
- The trailing edge of the pulse crosses the Runt Low Threshold in a negative direction; and
- No portion of the pulse crosses the Runt High Threshold.
When set to Negative, the oscilloscope triggers when the following conditions are met:
- The leading edge of a pulse crosses the Runt High Threshold in a negative direction;
- The trailing edge of the pulse crosses the Runt High Threshold in a positive direction; and
- No portion of the pulse crosses the Runt Low Threshold.
When set to Either, the oscilloscope triggers in either case.
Default Value: Positive
| Positive (1) |
The oscilloscope triggers on pulses of positive polarity relative to Runt Low Threshold that do not cross Runt High Threshold. |
| Negative (2) |
The oscilloscope triggers on pulses of negative polarity relative to the Runt High Threshold that do not cross Runt Low Threshold. |
| Either (3) |
The oscilloscope triggers on pulses of either positive or negative polarity. |
