:TRIGger Window Commands

- :TRIGger:WINDow:MODE
- :TRIGger:WINDow:SOURce
- :TRIGger:WINDow:TIME

The Window trigger mode lets you specify a voltage range and then trigger when the waveform either exits this range, enters this range, stays outside the range for too long or too short a time, or stays inside the range for too long or too short a time.

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

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