I like watching this guy on yt. Very informative https://youtu.be/vwwsTvlsTKM?si=LUofE094gIQH5ds8 https://youtu.be/tiOUd3NkOyQ?si=sxp4F9d0S9YmXcyz https://youtu.be/BDKLYsGyBVU?si=UT_MsSJ3J_CfjNRU

Oh I see, your looking for clipping/overload not tuning EQ. That makes sense. Yep, so you just need your scope running, and dial in the time/div (X axis) and voltage/div (Y axis) with a steady tone and you should see something that looks right. And turn on the trigger and set it above the noise level and you should get a crystal waveform as the frequency is stable and the trigger overlays each scan perfectly with the last. If you have AC/DC mode put it on AC because its a wave crossing the zero point.

Thanks for the help mate. Finally feel like I’m learning how to use this thing.

I would recommend getting a PC based scope.

You can get a brand new picoscope 2204a

Resolution on their base model is ass.
Why I got a VDS1022 instead.

Edit: Sounds like you're sorted already.

I got an old Kenwood 40Mhz dual channel CRO. It still works good despite looking like it's 100 years old. I've had it for sale on ebay for like 18 months, so clearly it has no interest. I need to rid it soon as the farm has sold and I got nowhere to keep it, you're welcome to have it.

I hadn't touched a CRO since my tafe days 20 years ago, but after 20 min of stuffing around I learned how to use it again for the most part, those old CROs are easy to use. I tried to use on of the digital ones in jaycar, for the life of me, I couldn't even figure out a single adjustment and I am not one easily beaten, so I know your pain.

Neet. Little jealous.

Still works good.

I wonder if there are any old oscilloscopes where I went to tech, they closed down the old site and moved to a new location and all the buildings have been closed since the move.

That's a sexy piece of equipment.

Tripple coaxial potentiometers? I'm practically drooling.
