Not sure what Horizontal Mode "Alt" does. Unless it's a vector mode of some sort with external input. That might not sweep. Otherwise it should be.

Alt mode normally traces one complete line per one channel before tracing the other. Chop literally does just that, jumping between both channels during a single trace. Looks really choppy, too. I have one of these that I got at a workplace equipment auction long ago. It was returned from the cal lab un-calibrated. I lost the tag from XTEK saying what was wrong with it. There is a way to lose sweep on the darn thing, but I'll be darned if I remember.

Eric, does the trigger LED go off if you apply a signal? Shove the probe in the cal-hole and see if it lights up. I honestly don't know where mine is , or I'd look.
