Need a scope, Is vertical sensitivity important?

Looks like a fun new toy.

A signal generator is handy but you can also build something. Do you have a breadboard and some parts? Lots of oscillators can be built around transistors or op amps. An arduino or other microcontroller can easily give you square waves and single shot pulses. Random electronic equipment has various signals in it, though I do recommend sticking to battery powered stuff until you know what you're doing. Anything that has an external power supply that produces low voltage DC can be lumped in with battery powered stuff. Just stay out of anything that has a line voltage power cord going into ir.

Watch Dave's video on how to not blow up your oscilloscope, and also check that the probes are set to 10X and leave them that way, there is rarely a reason to use the 1X setting and it increases the risk of damaging the scope.

Thanks for the suggestions, I do have a box of audrinos somewhere and breadboards, ill have to see what I can throw together.

Ive watched daves video and alot on the same topic, and read alot of articles and its left me confused. Seems like back in the day everyone suggested isolating the device being scoped and now they dont.
Going to research it some more as ill ultimately end up using the scope to test crt monitor circuits and IC's.
The monitors have seperate power boards but not sure if the chassis board is connected to earth ground. Ill have to test for continuity between earth ground and the chassis board and how to safely probe these circuits.
Alot to learn

No box but looks to be complete.




Whats the best signal sources I can use to learn on this with?

Should I get a cheap signal generator?

For now just setup the probes correctly, that is assign them to each channel with the colored rings and with them and the input attenuation set to 10x compensate the probes to get a symmetrical square wave.
Use ~200us timebase for that then start fiddling with timebase and vertical sensitivity to get a feel for basic operation after which go looking through the menus at the various features, even trying some to get the feel for them. Try engaging some measurements instead of needing to count graticules and tune this setup so to be able to bring them back with just a toggle of the Measure button.
Practice getting screenshots too so you can come here for advice with a picture, hopefully displaying an appropriate menu that shows settings.

You will at some point want a signal source however as a right of passage into electronics everyone makes a 555 timer or a Hex inverter oscillator both of which can be done with combinations of R and C.

While this thread is not with the same model DSO there is a pile of wealth to be had from it as we worked through the capabilities of Charlotte's new Siglent:

Have fun and try to get to a point of knowing what form a waveform will take before you even put a probe on it.
A little hard for sure with limited electronics experience but it will help you on the road to understanding electronic building blocks even if it's only at a conceptual level.

Enjoy your new eyes into a new and wonderful world.  :-+

So I cleaned up my bench a little bit and made a home for the scope, got the probes color coded, set to 10x and compensated.





Im wondering if the little green "ready" indicator is supposed to be flickering between ready and auto like this?

Normal in Auto triggering mode.
Remove probe from Comp output then switch to Single trigger mode and then reconnect to see what is does in Single mode. It's just to tell you the trigger state, Armed/Ready or Triggered. Single will STOP the acquisition. Try Normal too.
