:TRIGger Runt Commands

- :TRIGger:RUNT:POLarity
- :TRIGger:RUNT:SOURce
- :TRIGger:RUNT:TIME

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.

Use the `:TRIGger:CHANnel:LTHReshold` command to set the lower level.

Use the `:TRIGger:CHANnel:HTHReshold` command to set the upper level.
