Old analog oscilloscope question

[zvonex66x]

Hi all. I'm new here so if I do some mistakes please just tell me....

So, I have today trying to find some parts in my old collection of stuffs and there I see my old analog oscilloscope which I have used few years ago.
Now I figured out that I still don't know what is this two inputs/outputs and i will be glad to find it out...

Someone here know it for sure... so let's see..

Z is "Z modulation" or intensity of the beam (input).
The other one I guess is the time base output (sawtooth).

Thx, you are right with other one. i hooked up to my oscilloscope and it is sawtooth.

Thanks

Nice

The Z in an input, so you can use an external signal to change the trace brightness.  You can do interesting things with this with creative external circuits - such as placing markers on the waveforms, or even turning the scope into a video monitor (like my avatar).  The biggest downside to this scope is that it appears to be a recurrent sweep scope, not a triggered sweep, so it is more difficult to get stabilized traces, and the horizontal is not really calibrated.

The Z input is handy for vector displays too, you can play games like Asteroids on a scope, or use one of the various scope clock circuits.

I did a short video to show an example of how a HP 8340B used the Z axis:

Hope you find it interesting.
