JYE Tech DSO specs and feature test

Is this a toy? Well sort of but it does have some useful features.

[@edinny8001]

Just bought one of these fully assembled. My oscilloscope experience is next to nothing and the documentation that came with it was little to no help. Your video was not only extremely helpful but also right to the point and very well done. Thank you for sharing your extensive knowledge and experience in such a down to earth manner!

[@davec5084]

I don't think you are selling out. I really like your kit vids, I just purchaced a clock kit. It is a great hobby i make cabinets from wood and build custom stereos i normally just buy the chip boards ready made. I think I will practice making clock kits, and when I get better at soldering i may build a valve/tube amp keep up the good work your in my top 5 favorate channel's you have taught me so much thank you.

[@TechGorilla1987]

I built the old style DSO that had the plug in screen module and participated in the forums about the kits. It's nice to see that the company listened to a lot of the comments in the forums and implemented a lot of those ideas in further firmware revisions. Good on you JYE Tech!

[@andrestouten8483]

great video, ill like your style and you ar very honest about every thing . Go on like this!!

[@tommyciancia1439]

Thank you. This will perfect for measuring audio clipping! Good demo

[@ijskolibrietje]

Great review, you have convinced me to buy it as my first scope!

[@erebostd]

Wim Lex me too.

[@enlightendbel]

I mostly do audio and power delivery projects/builds and for that this Scope is pretty much all you need (that and an audio clip with a frequency sweep or a cheap Banggood function generator) Have to say, this thing has been rather satisfying and has had plenty use beyond the projects I usually do. Best 20$ in electronics I ever spent tbh. I recently also bought the DSO188 which actually comes with a battery and goes up to 1Mhz. Also just 25$ and rather well reviewed.

[@NickT6630]

Great review. I got mine today and assembled it. Works perfectly. I will use it for measuring signals in my sound synthersizer projects

[@JerryEricsson]

Thanks, I built one of these while spending the winter in the Mohave Desert of Arizona, I used a little component ID device to sort out the parts, then soldered her together using a cheap USB soldering Iron. Had nothing but trouble with her for the first year, never got it to do squat, then one day I was posting a question about it, and my own question rang the repair bell! The rotary encoder was not responding to my input.I tried replacing it, and the little guy came to life.

[@JerryEricsson]

I bought one of these last year, and put it together while we were in our RV down in Arizona. Never could get it to work, and one day I posted on a video such as this one, nobody had any idea either. Then one day, I came upon my comment, and it dawned on me, the rotary encoder was not working when turned in the backward direction! So I ordered some cheap rotary encoder's off Ebay, and replaced the one in the unit. I had to modify the case slightly as the new one was a bit thicker, but after the replacement, it now works like a new machine! I guess there are times when you just have to listen to your self.

[@Lordvoldemore]

Been looking for a video like this. Thank you.

[@jaynone9262]

Ordered 1 today. Like your honesty. I have an old BK precision 1570.Duel time base. Ordered new probes for it also. The one on it probably 40 years old.Its just 20mhz but it works. Needed something portable. 73s

[@RonanCantwell]

I got one of these a while back. Like you say, for audio frequency circuits it's actually a handy little tool. It'll never win any prizes for accuracy but for taking a quick look at signal levels etc it's great. To power it, I bought a handy USB to 9V adapter from eBay (I think) which cost about £1.50 delivered. This lets me run the unit from a USB power bank.

[@xeroinfinity]

thats a neat little testing device. especially for the price. Im sure it can be useful for smaller projects and testing lower voltages. Never seen an oscilloscope that small, and it fits in your pocket! I need one of these! lol Thanks for sharing!

[@amicklich6729]

Cool little tool with limitations. Same with some of the multi component testers. They have a time and place if it's what you got :)

[@atomicskull6405]

You can now get these fully assembled for around $30 off ebay. Very useful for RC modeling where you'd only be using it with low frequency PWM and serial data signals up to a few hundred hertz at most. If you use it with a wall wart make sure it's regulated 9v and not just an unregulated wall wart (which will damage it) An unregulated 9v wall wart actually goes up to 13v-14v depending on load and it cannot tolerate this. Most common wall warts used in consumer electrons are unregulated.

[@Enigma758]

I was inadvertently using a 9v AC adapter with the scope (had assumed it was DC) until I noticed the ripple and then switched to a 9v DC regulated. Hopefully, I didn't damage the electronics - it still works fine. I believe there is diode in there for blocking reverse polarity. Also, there are knockoffs, so make sure it is the genuine JYETech product before buying.

[@TheFarout69]

I bought a pre made one because I could not find the kit. I got this for audio projects so I feel like it was a great choice for my needs.

[@DavidTorres-kl2rt]

thanks for your video a frend from mexico good video

[@juvenalalvarez9535]

Great video. It can work on automotive sensors? Thanks.

[@jasejj]

What would really be handy with one of these devices is if they could implement meter (and maybe device test) functionlity into it. An all-in-one scopemeter like that would be great.

[@TwoBlackMarks]

I ordered one, have not testet it yet, but was going to try to check LIN, CAN, PWM etc. signals in cars, if it is fast enough. And it also works for to check for bad connections and other stuff sometimes a bit easier than a multimeter. Since it is so small it is very easy to take with you compared to a big/"real" scoop. If it does not work, it is not a really big deal since it is so cheap anyway, then it could be used to practice with atleast.

[@ThriftyAV]

Is 70MHz enough bandwidth to do tape path alignment? I went with a Hantek DSO5072P .

[@royelectrotechnic8711]

Sir can you show us testing some components like diodes and resistors etc? Thank you so much for your time and sharing us with your thought.

[@ThriftyAV]

I have the 2 Channel JYE on my Banggood wishlist. I assume that the 2 channel version has the same bandwidth issues. I will just save my money and get something better. Thank you.

[@browncr1164]

I ordered this unit and didn't take but a few hours to put together, I miss the old Heathkit projects.

[@basilsaverimuttu682]

Thank you for your reply, but Will you be able to do a demonstration? because i am still not clear? Thank you sir.

[@DennisMurphey]

I only work on Vacuum tube Amps for Guitar use. Only, I need a audio sound tracer that can model the sound wave and show what the Amp is receiving how is it conditioning and amplifying the sound. I am retired therefore poor. would this little device help me in debugging, tracing and tuning sound signals with the amp, tones and bias adjustments. ??? Dennis in Virginia

[@MrMustang1973]

I just pick up one of these for car audio and its my first scope. What is meant by duty cycle %?

[@islanderwinder]

I do a bit of Guitar tube amp building & repair would this be a suitable scope or does it need to a higher voltage rating ?

[@MrAletube]

It can stand voltages,I would use a 600 volts cap in front and a 10x probe.being only 200khz bw,if you have some kind of higher frequency oscillation inside you won't see it.Also it is very sensitive to mains frequency,in proximity of transformer it's easy to pickup couple volts of hum.

[@youtuuba]

Maximum input voltage is 100Vpp.

[@reddragon27284]

Looks like a great little audio tool. would be interesting to try and make it battery powered.

[@louishiggins381]

It will work with a 9v battery with a barrel Jack adapter

[@bruceburgess3580]

Have one on order, also a probe and small signal generator, for all I'll do with it this will be perfect for my repairs.

[@12voltvids]

For what it is, it will help people trace minor audio circuits.

[@HA7DN]

Does this thing have features like freq count and FFT inside?

[@RyanUptonInnovator]

Can you overclock it to increase the bandwidth?

[@keithking1985]

i noticed that you only connected one of the ground clips when you used your proper scope. was that important to do that????

[@Tocsin-Bang]

I built the older one a few years ago, but it died. I've ordered this one, it's more than I need, I never work above 100 kHz.

[@basilsaverimuttu682]

hello, on the oscilloscope what is the purpose of the external trigger could you explain if you would please? thank you sir.

[@12voltvids]

External trigger is just that. You can have your scope traced triggered by the measured waveform, by triggering when the voltage hits a certain voltage level, of when it starts increasing or decreasing, or you can have an external source on a second or 3rd input. In this case that external trigger is used just to trigger the trace, or in the case of DSO, trigger when the capture to memory starts.

[@gblargg]

Generally you want to look at a tiny portion of the waveform over time. Sometimes this corresponds to some aspect of the waveform itself, like where it crosses zero. Other times, you want to see the waveform only when some *other* signal is changing. This is what a separate trigger is for.

[@fongy200]

20 bucks to find out the foil side on poly caps is a bargain. Make sure you dot the foil end with a sharpie. Great stuff.

[@PaulMoorhousehankooks]

Will that measure sign waves for ssb cb rigs

[@MrJoaoantonio]

Muito legal!

[@jackietrove4637]

Is there any way to get the FFT function out of this meter, perhaps by exporting data to a laptop and running it through some a software program?

[@youtuuba]

The User Manual says that the scope firmware supports capture buffer data export via serial link to a personal computer, but the kit does not come with the connectors to implement it, and the case design does not have provisions for it. Assuming that a user can hack this up, then you can do whatever you want with the data once it is in your PC.

[@MrWhaatay]

This fully built for $20 or the DSO 138 mini in kit for $13 with the fun of building it? Read the knob is easier than the push buttons of 138 for adjustments.

[@markgrunenwald2670]

Would this little scope work fine for checking switch mode power supply readings? Thanks

[@12voltvids]

mark grunenwald Yes provided you don't exceed the max input rating. A 10x probe would solve that.

[@markgrunenwald2670]

12voltvids , Great thanks. I ordered it. There's a rechargeable battery conversion kit I ordered with it. It all fits inside, so it's portable. Love your videos, I'm learning a lot! Thanks!

[@keithking1985]

@@markgrunenwald2670 could you leave me a link to that batterie conversion please. Thank you..

[@kresimir9006]

One question, for me important, could I with this scope track signal in music synthesizer and visualize from which point I have unwanted white noise in it ?

[@12voltvids]

Probably as audio doesn't need much bandwidth.

[@kresimir9006]

@@12voltvids Many thanks! I will give it a try :)

[@lmt200ish]

Would this be sensitive enough to test for the outside foil on capacitors? Would be handy if something this small is capable of that.

[@12voltvids]

Probably not. An analog scope yes.

[@lmt200ish]

@@12voltvids Thanks

[@nickgc1234]

you know a lot about this stuff im just getting into this. could you tell me if this would work on a car to check to see if there is a data stream to ecu or signal to maf etc

[@12voltvids]

It will certainly allow you to see and capture the data burst on the bus.

[@cubis]

For just standard things like viewing audio waveforms like standard audio or raw waveforms, this should be ok?

[@12voltvids]

Yes audio fine. No good for video.

[@cubis]

@@12voltvids thanks for the reply! Also, what about subsonic stuff like low frequency oscillators? Was wondering if the sensitivity would be an issue there. If i did decide i want something more robust, what would be a good value scope that won't break the bank? Thanks again!

[@12voltvids]

@@cubis It will work fine with low frequencies.

[@stephenmaneleys6983]

What bandwidth would I need for a DAT alignment. Prefer not to opt for the $200 scopes

[@youtuuba]

Seriously, if you are getting into things like DAT alignment, you should not rely on cheapo test equipment. Garbage in, garbage out. Also, the practical bandwidth is NOT 200kHz. The specifications say that the ANALOG section's bandwidth goes up to 200kHz, but with my own experiments with this scope, it can't be relied on to give real waveforms above about 50kHz; after that, the sampling rate and other limitations are what dictate scope performance, and conveniently the specs don't mention that number. The demonstrations of higher frequency signals given in this video are not indicative of the real performance. In my own tests, it will mislead you by showing a nice looking waveform, but there is a good chance that it is actually lying to you.

[@MrWhaatay]

Under 200 cuz it was a distored wave with some peaks higher than others. It lokked mor like 150khz was more like the max.

[@keithking1985]

Can you check mains with this??? I'm 240 mains voltage!! Because i got one dismorning and I'm putting it together 2moro but I'm not going to try unless it defiantly can! Did I hear you say 500volts on 10X probe setting????

[@12voltvids]

500v on a 10x probe is 50v to the scope.

[@keithking1985]

@@12voltvids So can you check the mains with it.. or is 50v the max absolute???

[@12voltvids]

@@keithking1985 With a 10x probe yes because 240v will have a p-p of about 330 which would be 33v on the 10x probe. 50v is the max it can measure with a 1x direct input 500 with 10x

[@keithking1985]

@@12voltvids Thank you very much the kit build I got had the alligator clips and not the probes. But I bought a pair of cheap ones that has 1X and 10X I to use with it..I'm glad to hear that it can do mains.

@@12voltvids Thank you Mr 12volts that makes sense. Plus the kit build I ordered has those black and red BNC alligator clips with it.

Hey guys where can I find the esr meter shown in some of this guy's videos

[@12voltvids]

The shop I bought mine at, main electronics has now closed their doors and I do not know who is carrying them anymore, but if you search you should be able to find one. Mine is the Disk Smith design.

[@Sloxx701]

Bob Parker designed the Dick Smith ESR meter that Dave uses, they don't make them anymore. The replacement design from Bob Parker is the Blue ESR Meter, and you can find it everywhere pretty much. Just google "Blue ESR Meter".

[@vjekoslavcvetnic7500]

I have MESR 100 esr meter and is very accurate.

[@thetechgenie7374]

That sine-wave looks clipped.

[@ianpaul6369]

Maybe they can send you their DSO 094 to evaluate

[@jameshanley9102]

if it can trace sound circuits then it sure has its uses

[@12voltvids]

For someone that only works on audio circuits this is all one needs. If you need to look at IF circuits in a radio, well it is going to fall short, as IF is typically 455KHZ for AM and 10.7MHz for FM radio, but baseband audio this will do the trick, and it is dirt cheap.

[@ventureelect]

What do you think of your other scope that you are using. Would you buy it again.

[@12voltvids]

My tektronix scope is the best. I wouldn't buy the dso again. This one won't display complex wave forms like video.

[@swansealoaf1999]

Can it measure rf signals

[@12voltvids]

No, not enough bandwidth.
