Uni-T UTS3021B Spectrum Analyzer Box opening and Introduction

[@jakubczajka4275]

I agree with you! Let's test everything you can. Especially PSUs of all kinds and class D amps, as they are the main suspects.

[@KissAnalog]

Thanks so much!!

[@jstro-hobbytech]

Awesome piece of gear man. Spectrum analysis is new to me so I'm game for anything. I love uni-t products. I've been wanting the ut12 lcr meter. I'm excited for ya Ed. Let the games begin!

[@KissAnalog]

Thanks for the feedback Joey! It really feels like a quality built instrument. I also really like my generator.

[@jstro-hobbytech]

@@KissAnalog I'm gonna text ya about something my friend

[@KissAnalog]

OK thanks!

[@aquinamedia4508]

I recently got the Uni-T UT161D multimeter (European version of UT61D+ i think, fused at 1000V rather than 250V), really good quality stuff, actually like it way better than my Fluke 175 at work.

[@aquinamedia4508]

Also tested the Uni-T against the Fluke 753 at work with great results, even the electrician that performed the tests were impressed!

[@KissAnalog]

Thanks for this great feedback! The UT61D+ is a much newer meter design and I like it better too. Only around $80 - I need to get one:) Here's a link: amzn.to/3TDU2VP

HI Eddie, I forgot to tell you, I would really Like to hear about your experiences you have had. Thank you 😀

[@KissAnalog]

Sure thing! Thank you!

[@jorgenieves9787]

Cool video! Uni-T has pretty cool stuff at very affordable prices 👍

[@aquinamedia4508]

Very much so, i'm really impressed with the multimeter i got recently.

[@KissAnalog]

I agree - I like my generator and this SA has the feel and looks of something quality made.

[@jorgenieves9787]

@@KissAnalog Yes good Quality is definitely present 👍

[@versace885]

HI Eddie, great video, very interesting. Thank you.👍

[@KissAnalog]

Glad you enjoyed it

[@pbaemedan]

Eddie, I would like to see conducted emissions and radiated emissions from your power supplies.

[@KissAnalog]

Thanks for your feedback! I will see if I can show both of these things;)

[@fatdragon509]

I would love to see you test some ham radio gear. A good one to test that's cheap is the baofeng uv-5r.

[@KissAnalog]

I'll check it out and see what I can do. Thanks for the suggestion!

[@RomstarOrion]

There are a bunch of us out here working on CB and HAM rigs, and it would be good to see how this stacks up and if it would be worth it in a repair shop or if something like the GW Instek MDO series would just be a better option for repair and verification work for radios and amps. Oh, and some mention of the price would be nice, because I can't find a price for it and the get a quote option wasn't working as I type this.

[@KissAnalog]

Thanks for this feedback! I'll have to compare it side by side to my GW Instek MDO scope.

[@fredflickinger643]

I would love to here about your experiences in the career realm as many of us are going through what I assume are similar circumstances.

[@KissAnalog]

Thank you! I appreciate you!

[@ELXT93]

Wow nice toys.. i have a uni-t meter and its good and its cheap

[@KissAnalog]

Thanks for the feedback!

[@kb6dxn]

Show how to use a Spectrum Analyzer would be great. How to hook them up safely and all the menu's would be great. There is a lot to a Spectrum Analyzer, I use one when checking Ham radio's transmitters and audio amplifiers. Once you have one and learn to use them it's hard to be without one.

[@pa3eka]

I used always a 10 or 20 dB 50 ohm attenuator fabricated with 1/2 Watt resistors to protect the analyzer for To Big signals or when needed a adjustable attenuator , i have ones puts by accident a to big signal , 500 Watt RF , in my home made spectrum analyzer build around TV tuner, my attenuator was evaporated my TV tuner also died To much smd components :(

[@KissAnalog]

Thanks - I'll try to do as many as I can before I have to return it.

[@TRONMAGNUM2099]

Nice pickup. Very cool you got that from UniT. I noticed you linked to the GW Instek scope below. Is that what you recommend for audio analysis?

[@KissAnalog]

Thank you! I am leaning towards Picoscope these days;)

[@davidluther3955]

I HAD TO USE A SPECIALIZED SPECTRUM ANALYZER TO PROPERLY TUNE THE RECEIVER ON PHOENIX MISSILE TO A CLASSIFIED FREQUENCY WHEN I WORKED AT HUGHES AIRCRAFT AS AN ELECTRONIC TECHNICIAN.

[@KissAnalog]

Thanks David for the great feedback. This is an application that these can be used for. The one you used was probably very expensive;)

[@davidluther3955]

@@KissAnalog IT WAS GOVERMENT MONEY SO I IMAGINE IT MATTER WHAT IT COST.

[@KissAnalog]

Yep - so that's why you were probably using Fluke multimeters too;)

[@JohnUsp]

Are you going to do Part 2 with several tests to compare its quality? (maybe comparing against Siglent and Rigol specs)

[@KissAnalog]

Yes, thanks I'm going to do a series of videos using this;)

[@jstro-hobbytech]

Go Eduardo!

[@KissAnalog]

Thank you for your generosity Joey!

[@pa3eka]

Congratulations with spectrum analyzer very sad that it starts at 9KHz not usable for audio 😢 , and thermo camera is gift to be sure that you give a nice review ! 😂 The world is open for you , how deep can you measure and the the bandwidth minimum between several strong signals without the noise floor is rising ? That was IMD measurements with Short Wave SSB amplifiers. The old HP 141 mainframe and 100 mhz plug in 50KG ! At least my back pain comes back immediately 😅

[@jakubczajka4275]

It is still usable for audio. Check the output of your DAC and try to do something with all that HF noise. Or just ignore it and enjoy the music.

[@pa3eka]

@@jakubczajka4275 your right , i do not building DAC of Class D amp . Just simple tube amps .The day,s that i could hear noise is a long time ago below , 6 kc it drop,s very hard , so enjoying music is difficult ☹️

[@pa3eka]

@@jim9930 lucky enough it fits under the table , and never tried to place it on a shelf , i think it was more then 600 mm deep , so i used it standing upright.

[@pa3eka]

@@jim9930 your right i have the GWInstek MDO2072EG with built in analyzer usable for my audio as a radioactivity is very very low , 40 years it was my no1 hobby , making some audio amps maybe CB Tube Transmitter again , thats where it started 55 years ago , good old times 😃

[@pa3eka]

@@jim9930 yes i was looking for a couple years for something lik that , and i was the first who was buying in the Netherlands ,and still happy with it Jim

[@garydirkse9900]

nice toys, I need to see specs on the i r camera too. Never trust the camera to yield accurate info from shiney surfaces, like clean aluminum

[@KissAnalog]

Thank you - so true. I find placing some tape on shiny surfaces makes a big difference.

[@garydirkse9900]

Yes. Black electrical tape tested over 95% I R emissive

[@Psi117]

Is there a problem with your camera focus?

[@KissAnalog]

Thanks for asking! Was it out of focus for awhile or just going in and out of focus?

[@Psi117]

@@KissAnalog Cear until 3:25.Out of focus until the end. And the previous video (Vanpower) is also out of focus on the indoor shooting (like in this video), but clear on the outdoor shooting. The others recent videos are crisp.

[@KissAnalog]

Wow, I see what you mean. I think I know what happened, it should be in 4k but I think going outside and then back inside a setting wasn't correct so the camera tried to compensate which makes the resolution poor - making it look out of focus:( Always something lately! So many things to consider just in the production and then in the editing. In editing it will show a lower res sometimes to speed editing...so I must not have noticed this.

[@pbaemedan]

Eddie, does the spectrum analyzer have a peak detector?

[@KissAnalog]

Yes I think it does. If you stop the video where I show the still photo - you can see on the list of measurements 'Peak'. I'll have to show how this works.

[@microknigh7]

Sorry if you said it in the vid Eddie, I guess I missed it. But what's the price on this thing?

[@KissAnalog]

Thanks for asking! I'm checking to see what a good price is and if I can get a link.

[@yurkshirelad]

I assume this kind of analyzer wouldn’t be used for audio signals?

[@MrMersh-ts7jl]

correct. although 9khz is in the audio range, something for audio would be more like a dynamic signal analyzer which works in the 1hz to 100khz range.

[@KissAnalog]

It would be great for any digital audio including Class D amps and switching power supplies. That's what I want to use it for to show the good and bad - and hopefully that the good far outweighs the bad;) A great option is the GW Instek MDO scope that I have. Here's the link: amzn.to/42JUM02

Uni-T UTS30321B Spectrum Analyzer @ US $1,439.99 is out of my price range unfortunately.

[@KissAnalog]

Thanks - but this is very low cost ofr a real spectrum;)

[@Chris-hy6jy]

I think you need to fix the camera focus before your next video 😉

[@KissAnalog]

Thanks - was it moving in and out of focus, or was it out for periods of time?

[@Chris-hy6jy]

@@KissAnalog just a blurry image for most of the video. Don't know if it was the camera or some issue with the editing / effects you use.

[@KissAnalog]

Thanks - did you force the resolution playback to 4k? I uploaded in 4k so maybe your playback is in auto mode and chose a lower res playback? I didn't notice this in editing the video.

[@jstro-hobbytech]

Uni-t make awesome stuff but even on aliexpress their gear costs way more than the normal stuff one would buy. Like their linear power supplies and bench dmms. Never goes on sale either. Im a fan of their gear, i wish they'd do the third party certification. Rigol dont send anyone review gear it seems. Dave gets everything though because his community is so large with massive purchasing power. I used to always want keysight gear but they need to screw their head o straight and charge competitive prices for the stuff hobbyists would buy feature wise. Im soured on keysight for various reasons i wont go into. One of their ambassadors made me look like a jackass and the person i told about it probably thinks i lied.

[@KissAnalog]

You are so right about all these statements. Uni-T is really trying to do things right - and they have a big gear release soon. I can't wait to see what it is. They contacted me and I think I might get a discount code for my viewers. They like the traffic that they get from this channel. Rigol said that they would send me a loaner - and I was going to buy one if I liked it. The new scopes are doing well, so now they won't respond to my emails - so I am done trying with them - and I decided that the cost is a bit high. The lowest line misses a few things, and the next one up (which is the one I was interested in) is a bit expensive. I told Keysight if they added more deep memory that they would make a killing with their lower cost line that they came out with. Very nice, but spendy - especially since they don't' have deep memory. They did double it - but it is still on the small side for the cost. It would be worth spending more with them if they would just offer deep memory - which is a very simple thing to do. They loaned me a scope once but that's it. It takes me time to ship and money...
