Oscilloscope basic question
« on: March 16, 2019, 07:46:45 pm »
hi guys, very first  post for me and great to be here. getting into electronics more and more with the time.
i purchased a second hand very cheap Grundig Oscilloscope Mo 32-30Mhz in order to get more understanding and learn. i found it for 50bucks and got it straight away.
i can't find infos about  the time B section which is ms/cm with delay knob on the side.
of course the manual wasn't with the oscilloscope and i can't find it on the internet.
ghere a picture of the oscilloscope

I think that controls how quickly the trace redraws on the screen.

No magic about it. You have a scope with two timebases for the horizontal sweep. "A" is an addition to normal scopes (to my mind unnecessary, but there might be a reason), "B" is the standard type of timebase.
The "delay" knob does exactly what it says, it delays the sweep after triggering. This is useful when you have an event (eg, a pulse), but want to examine in detail what happens later.

Did a google search of "Grundig Oscilloscope Mo 32-30 Mhz manual" and it brought up plenty of manuals.


That is a nice scope with duel timebases a very nice feature. That will let you look at two different traces of different frequency, have fun playing. Lot of fun for 50 bucks
