If so, the display you show looks very much like it includes a marker. What have you selected on the 8600a? The control with the button depressed, if you rotate it does the dot move?
Please confirm this before we move on.

correct, I have been playing with my monster analog scope a bit, and if you have it in the right mode, IF you unplug the line you have hooked to CH1, you should get a single non-moving dot on your scope, because ALL the sweep is from an external source, anything else, and it not in the right setting, and it wont work. but if it does show a dot, and then a line when hooked up, then... things a a bit more complicated.
