Thread: Old oscilloscope X-input, Y-input

Hi!. Today I've reincarnated an old "Osciloskop MA 4060" oscilloscope with vacum tubes. As far I can see I can tell that it is working, got a stable `dot`.

It has 2 inputs by N-female connectors one for X and one for Y. When I connect a signal (doesn't matter the type just to be AC) to X-Input which has for example 5Hz I see a dot that goes left and right 5 times a second. Same happens when I connect the signal to the Y-Input but the dot goes up and down.

My question is, how do I need to connect the signal so that I can see it in `real mode`. I mean if I connect a sine wave signal to it, I want actually to see the wave on it. I assume that I'm missing the time base or some time factor ...

Thanks in advance !

There is no timebase mode ... nor a switch for modes



This is a picture found on the net. I'll take a picture of it tomorrow and post it in a bigger resolution.

As far as I can remember there was no such thing... Will check it tomorrow and give it a closer look.

Anyhow, if it doesn't have that switch and its in x-y only mode, is there anything to be done with it ?

I hope there is ... I remember I twisted all the buttons on the rig ... all gave different results but none of them gave me the wave form on the screen

I'll post some pics with better quality tomorrow and try to see if I can find a switch for changing modes and see if its operational.

Sorry it took me so long to reply. I fixed it. One switch had a mode with the sign "/\/\/\" on it. On that mode, when there is no signal at the input I see a horizontal line not a dot. When I input a signal I can see its shape )

I'll post some pics later so that you can see how big is the thing... and how old )

Thanks to everyone who tried to help me.
