# Runt

The Runt trigger mode finds a positive or negative pulse that has a smaller amplitude than the rest of the pulses. This trigger mode uses a lower and an upper threshold level.

Normal pulses cross both levels.

Positive runt pulses cross the lower level but not the upper level.

Negative runt pulses cross the upper level but not the lower level.

- Source — Select one of the analog input channels.

- Lower Threshold — Sets the low threshold level.

- Upper Threshold — Sets the high threshold level.

- Time — Specifies the amount of time that pulses must be wider than.

- Slope — Select positive runt pulses or negative runt pulses.
