This feature is darn finicky. Sometimes I have the feeling it doesn't really work. I try to use it to trigger on rare pulses. You set upper and lower voltage levels + the time in between these. The DSO is supposed to evaluate the average (I think) slope in this zone. Most of the time it doesn't work. When choosing a small voltage window to get a better estimate for the local slope it usually fails to trigger at all. The manual is pretty sparse with information other than "set this to that". The "pulse trigger" function seems pretty 'confused' most of the time as well. The adjust knob for the 'slope time' (as well as hold-off and some other stuff) is a pretty sad thing. It comes with a push-button, but doesn't use it sensibly. Currently one has to keep spinning the button for MINUTES to get from value A to a far away value B. One option would be to use the current time s/div value when pressing the button. That could speed up things considerably. Unfortunately I don't think I will see a firmware update any time soon, as this is the bottom-end range of their scopes, rebranded Chinese product I think. I think I will keep Lecroy support busy for longer than they will desire.
