Hameg HM712 - unknown input-connector

Hi there.

I found an old (2-channel) Oscilloscope: Hameg HM-712. It works properly.
On the rear there is a mysterious BNC-connector named "Z-Input".
Does anybody know what this is for?

Thanks in advance.

That should be an input to modulate beam brightness, usually something
in the 0...5 V signal level.

Sometimes they'll go negative to increase the brightness, as well.

As a related question, what are they commonly used for? In all the time
I've had an oscilloscope that had such an input, I've never actually
come across an application where it seemed useful.

In this case (sounds logical - i'll test it later), the modulation of the
beam-brightness makes kind of TV-pictures possible.
Something like X-Y modus and picture-information in then modulation.
Am i right?

Displaying brightness-modulated picture images, for a prank.
