In electronics school, we only had 20 MHz scopes for the most part. The lab had a single 100Mhz scope, but you had to get to class very early to get that seat.

That's a cool little scope. Especially since it has a component tester which is a really handy thing to have. I suppose that other commenters may have a point about aliasing, but that is just something that beginners need to learn about. It's all part of the black magic wizardry :-)

Great to see you also made a video about this device. 😀
I have a simple component tester and and use it a lot. The main disadvantage is that the cheap one i bought has no decent case and uses a separate 9 v battery. Some😢 days ago i was looking for a better one and decided to buy this nice device. It is more expensive as just a component tester however for the additional price it offers a lot of extra's (not mentoned in this video it also has an IRcode checker a temperature sensors etc.). Also it is around the same size as just a component tester so it will not use much space on my workbench. Hope it will arrive in a few days to test and use it myself.

Thanks for the interesting YT. Years ago I purchased two different M-Testers (aka Mega328), mainly for testing transistors. I was interested enough in this device to download the manual. Which says those funny little connectors are called MCX connectors. I would use a short RG-174 adapter cable to reduce any stress placed on the DSO-3TC connectors. I may end up buying one of these just because it's a cute, small tester with lots of basic functions for a low cost. Or wait to see what additional stuff is added to future devices of this type. It sure beats the Eico & Heathkit non-triggered vacuum tube 5 inch scopes I started out with! Yeah, I'm another old retired electronics guy. I used to service medical electronics equipment and found your choice of an EKG waveform interesting as well.

9:15 from what I understand, you have to move the cursor to the right until it is on the right blue arrow to the right of the center line., then you can adjust the trigger by moving up/down.

I have the tc-2. basically the same thing. As a beginner, im learning stuff still, and it is great for me

[AndySpicer]

I’m ordering one right now just based on the IR Decoder! Everyone I need one I end up breadboarding one which the of course gets disassembled a day before I need one again.

[Daniel-lksy]

And if you know enough about electronics at that point you can expand its capabilities by using multipliers and dividing devices electronic wise to get other ranges that it will read only because you downgraded or upgraded the range what is receiving and sending out like if it's sending out a certain signal you can run it in a higher range with a multiplier

[barrybogart]

I already have a component tester. and AWG. So I just ordered a Zotek ZT-702S which is $60 and includes an actual 10mHz (Real Time Sampling Rate: 48MSa/s) scope and a 10, 000 count TRMS DMM.

I have ZEEWEII DSO1511G, for literally 60 euros I got oscilloscope that gave new way to see how circuits work. Not lab grade device but works great for beginner.

[battlecoder]

Regarding the trigger level, you actually had it selected when you were scrolling through the menus. After AC/DC, the next item highlighted when you pressed right, was the blue trigger level arrow.

[espenbgh]

Impressive you have one of the old IMSAI. Remember reading and saw the picture about it. Waited until Sinclair sendt Specturm 48 K on the marked.

[victoria]

Thank you. I got suckered and I'm waiting for delivery but at least as a beginner I know I'm good for starting out and that I should be okay using this.

[portblock]

100% agree on the teaching side, my opinion audio range is the best range to teach in, because we can hear it. one of my first projects many moons ago (1970's) was signal tracer, now if I had a little scope like that to view the signal as well that would have been awesome.

[paulperano]

I'm seriously considering getting one. I don't have the luxury of having a workshop, just a large IKEA desk and cupboard. Sometime it's a pain in the butt setting up my 100Mhz Oscope.
Geeze ... when I was a kid I would have given my brother's right arm for one of these things.

[pravardhanus]

I think the connectors on the top must be SMB.
And the component tester connector is ZIF (Zero Insertion Force) socket.

[paulperano]

Got mine a couple of weeks ago. Very useful for checking basic stuff without having to get out my desktop Owon. I think it'll be great for learners on a small budget, or if you do audio and need something in your toolkit.
Is it amazing - of course not. However for simple low freq stuff its enough.

[jaymclemore]

I wish you would teach a class, I enjoy your videos very much!

[ksamprocar-ohft]

Hello, Can it be used in automotive diagnostics? Does it support CAN, LIN and FlexRay protocols? And if not so what is the affordable one do you recommend for automotive repair?

[rjazz]

It would have been nice to show it in actual use, thanks for the vid!!
