Juntek JDS2800-60 arbitrary waveform generator from Banggood

[@hoofheartedicemelted296]

Sir you covered just about everything here. The answer I required was about halfway through the video, but I watched till the end anyway. I do that with all your videos. There's always a nugget in there. In UK money it's £82.86, ( as of today 4/9/22 ) that's a bargain sir. I got "Electronics for dummies" by Wiley after watching a load of your videos. I'm hooked now. And yes I miss the 70's too. Thank you sir.

[@DustinWatts]

As an extension of my previous comment on the Micsig, you are basically costing me money, because now I want this too! ;)

[@learnelectronics]

It is very nice

[@mikin.6595]

0.01µHz(0.00000001Hz) is great resolution and we didnt see it on video.Can you please show us this resolution steps on for example 10kH frequency?I would like to see how tuning looks like on signal generator screen.And is this resolution available for example on 1MHz output too?

[@microreniassance2929]

Thanks for the great video. I've subscribed. I do have a question, though. If I wanted an output signal of 455KHz with 30% modulation at 400Hz, can this thing do that? I do a lot of tube radio work and alignments often require modulated, AM signals. Can this do that? How would you set it up? I've looked at the instructions and there's no real guidance there. Thanks again for the great video.

[@BradKwfc]

Great video and WOW that scope is impressive. That's exactly how a scope should be designed!

[@georgejbaker]

Hey Paul, can you make a short video to explain what a function generator can be used for in home electronics.

[@benrish1095]

Looks nice. How does it compare to your JDS6600 ?

[@packratswhatif.3990]

Oh yeah, you gotta love all the electronic do-dads. Even for the beginner, you can afford at least an entry level devices .....just WISH they had this stuff when I was younger and gettin into electronics. But , better late then never !!!! Thanks bud !

[@karlD1963]

Does it work right up to the max 60 MHz without too much distortion?

[@learnelectronics]

Square waves look a little rounded at 60MHz

[@dosgos]

Could we get 4 channels of output with same trigger with 2 of these function generators? Is there an easier way to get 4 channels without a mortgage?

[@learnelectronics]

Yes. They accept an external trigger.

[@captainpugwash4100]

Not bad for 65 bucks! Certainly in the hobbyist’s range!

[@bipolarchemist]

I'm down with panel mounting everything, but I'd prefer it all in a nice brushed nickel enclosure with some nice anodized aluminum highlights. As for that short BNC cable, yet another benefit of panel mounting 🤣

[@QrchackOfficial]

How well would it work for audio and control applications? I mean the 100-800Hz range as well as say, 1-10s long exponential decay

[@learnelectronics]

It will work just fine.

[@tav9755]

I am wondering what the impedance of the device is. Is it 50 Ohm or 75 Ohm? Thanks PS: keep up the good work!

[@roccorid]

Make your panel with brushed aluminum. A nice 60's sci-fi look.

[@johngibson3594]

What is this used for? Is it for verification of scope settings so you can adjust scope for best reading possible?

[@learnelectronics]

Used to test circuits by injecting signals and sweeping frequencies. Testing speakers, amplifiers etc.

[@GadgetReboot]

I like the compact design of that panel function generator but yeah, a keypad would make it much easier to work with than scrolling all the time. I remember not only television and audio in one wooden console, but a mini bar and fake fireplace with the lightbulb inside the rolling orange barrel. Back when some cars had eight track players in them.

[@learnelectronics]

I loved the ca-chunk when the 8 track changed tracks.

[@WallStreet749]

I was surprised you didnt open it up to look inside .. :(

[@psynautic]

hey it makes me sick that you have to write a disclaimer about your health to prevent trolling. i hope you're still doing reasonably well health wise and i love your videos! Keep it up

[@learnelectronics]

Doing well, thanks

[@Gideon_Judges6]

Did I miss the sawtooths or it just doesn't have it? Are we supposed to smooth the stairstep waves?

[@MalagasOnFire]

If you like the JDS2800, check out the JDS2900 from juntek :P For noise and avoid ground loops use power bank 5V

[@johnadams9558]

Did you mention any USB? Need to feed it some custom drawn signals.

[@learnelectronics]

It has USB

[@MrBrymstond]

The 70's was a beautiful time.

[@InteraliaTony]

Thanks for the video. I have one of the older generators that you had trouble with in that presentation. Aside from it's own frequency counter mode being somewhat deaf it is a nice little instrument but with limitations. However, it does have a UI that takes some getting used to and the signal generator doesn't have a sync out . It looks like your new one doesn't either? - which is a shame. (can you comment on that?). The UI looks much better on the new unit. Your sine wave looked a lot cleaner than the old sig-gen I have at high output - and they both share the feature of an external 5v power supply. There are other Chinese function generators out there with internal switched mode power supplies that present some nasty voltages on the output. You could conceivably feed your new instrument with DC from a battery for the cleanest of output - but also give portability. Great feature. For the hobby end of the market we have some good choices nowadays. If you think what a hobby heathkit signal generator cost back in the day (comparatively) we are rather spoiled by what we can get now for so little. One final comment. The random noise output feature is often glossed over in reviews such as this - yet a good noise source can be used for RF filter testing. Simple noise generators can be built of course - but they often fall off in output severely over frequency. With the FFT function in your (rather nice) Micsig you could have perhaps shown that output over the frequency spectrum that hobbyists and radio hams commonly play in?

[@learnelectronics]

Tony, you have some great points. You are right about the lack of a sync input. That is a shame too. I'm not very experienced in the RF side of things. I always avoided it at work and have only really started to get into it since last year. There will be more videos on this unit.

[@InteraliaTony]

@@learnelectronics I was surprised that Banggood were charging so little extra for the 40MHz and 60MHz units. It seems silly to contemplate the 15MHz unit. The better models more than cover a "constructing radio ham's" HF requirements. Dave over at EEVBlog shows how to sweep a filter to produce a bode plot and his function generator has an output that triggers his scope [kzbin.info/www/bejne/q36rY5t9q9aboqc] This was what prompted me to ask you that question. But no matter, your review generator is still good value. At a recent visit to Rigol they thrust a Micsig scope into my hands and it was almost love at first sight. I might have weakened there and then if I didn't already have two good 'scopes.

[@marcinmakan9710]

Hello, how can I calibrate this generator to increase the frequency accuracy? What menu to select and which steps to go exactly? Can someone share the procedure please?

[@jw228w]

Always like your videos. trying to learn how a function gen and scope can be used to diagnose and fix electronic circuit.do you have videos on using these test equipment to identify a problem and correct it? thanks john

[@yambo59]

Damn Paul, you sound like me - I miss the 70's and early 80's so much, what a different era we had so much fun no such thing as school shootings and the rock music legends were GREAT-! I dont know what happened to music but its all degenerated to just soulless, thumping distorted bass with no imagination and a serious lack of the great songwriters and players we used to enjoy. Fortunately I still have all my old albums and Harmon Kardon turntable with its 2 pound platter to go with my CD player, both now seemingly out of date but I could care less.

[@learnelectronics]

I would love for real music, played by musicians to make a comeback.

More thought on using Juntek as the company name would have been beneficial. At first glance it reads JunkTek.

[@learnelectronics]

Indeed. Chinese company names can be very odd.

[@billpeiman8973]

Its not an AWG if you can't define it.

[@JAKOB1977]

Here you go, thumbs down..out with the bathwater next time maybe use a second to actually show your SDS AWG setting for what you have going the first 2 minutes.

[@coldfinger459sub0]

But how clean is the signal??? For audio work ??? How MUCH RIPPLE!!! is riding on the signal???! To waist sensitive circuits !.

[@learnelectronics]

If you are worried about sensitivity and ripple on the signal, buy a $300 Rigol or Siglent or a $900 Keysight. This is stuff is just fine for the home hobbyist.

[@coldfinger459sub0]

Worried about the newbies not knowing the importance of a clean signal. I got my HP 3300A function generator for $60 it used to be not working two hours of work searching for the bad capacitors in the power supply it’s a beautiful function function generator. I got my HP 3312a for $85 not functioning it was just a power switch. My HP 8640B Signal generator $160 Nonoperating I fixed it power supply capacitor’s and one broken BNC connector terminal. I’m just learning as a hobbyist for fun. Cannot afford the new expensive digital equipment. Love the classic look of the old analog equipment for a fraction of the price if you’re willing to do a little work to fix them and you end up with lab grade equipment top-notch still to this day.
