Excellent video and I am thrilled to have one and be capable of doing amazing work assessing and mitigating emfs for my new career as a building biologist. As an RF engineer you did many of the things I wanted to know about. Thank you.

Outstanding video. You tell us what your going to do, tell us what to watch for, then do it, then tell us what we saw. This is the perfect way to do this kind of video and I simply want to thank you for your professionalism.

Your videos inspire me to continue my RF circuitry hobby and go deeper in the analysis tools! Thank you, Kerry!

Thanks very much for sharing! I work in location sound for TV and film, and the TinySA is a revelation for RF troubleshooting in the field!!

Very cool, nice job. Thank You!

Thanks for the review on the TinySA. Very well presented. Has helped me determine i really DO need one of these!

WOW!! Thank you making this fascinating video!

Some of the best videos I have seen with the TinySA Ultra are the ones your channel are producing .. most others, just do very crude shallow walkthrough, and likely from lack of knowledge on these topics. You take it to the ringer and you clearly are comptent on the matter while still explaining & demonstrating it, so I as a rookie can follow along. pls do more videos down this alley on different usecases with TinySA / Ultra and demonstate all these extensive features this device have, same goes for the PC app for the Tiny SA series.. A joy to watch.+1

thank you, very good presentation - clear and concise👋

Excellent review by comparing with HP SA. Thank you very much.

Excellent detail, many thanks. Subscribed and look forward to your other videos

Awesome! I wasn't aware there was a new TinySA, especially one that measures so high. 🤩

Excellent review and great detail in a very clear narration, Thanks

Absolutely brilliant, technically perfect and very concise review.

Great video! Thank you very much!

Kerry thank you for such a brilliant video.. Everything covered in just enough detail... As you say a device you would only dream of a few years ago. For the low cost its amazing tech. Keep posting great videos.. Rob U. K

Thanks for video I used much expensive HP measuring equipments like network analyzer, spectrum analyzer etc but then can only dream about this tiny field usable equipment

Great video !

Thanks very much for sharing your video which is very useful!

Some of what you said went over my head, as I'm more comfortable with digital and computer engineering. But I appreciate that YOU have both the equipment and expertise to test this device. Great video! Would this be valuable for a beginning Ham radio hobbyist?

Very good presentation.

A very impressive instrument, especially considering the low price. Thanks for the video.

Thanks Kerry, now I don't have to disassemble mine to look inside! ;-)

very informative video !

What a remarkable and inexpensive little device. Just added one to the tool box.

Thank you for this excellent video. I am hoping the software in the future will store frequencies detected to a memory automatically.

Outstanding review - thank you. Cheers from So.CA.USA 3rd House on the Left

Interesting review and product. As it has RF out does it maybe has a functionality to make Bode plots? And if the attenuation is known at very high frequencies maybe they could implement look-up table to correct for that?

Nice review. How about it's IIP3 level?

Amazing review - you convinced me to order one. Do you have to have an external 5.34GHz signal to calibrate the upper range, or is the built-in generator also sufficient?

Great video. Have you figure out a way to synchronize the SA with other any equipment( ex SigGen) to be on the same time or synchronized?

Kerry: When in Listening mode, could it be that the detector is for AM? Perhaps that is why the FM stations you were tuning to sounded a bit distorted. I could listen to FM stations here, but I did so (I think) by slope detection. What do you thinK? Thanks for the great video. Bill

Excellent review Kerry, thanks. I would be interested if there is anyway to add some sort of tracking generator capability externally to the TinySA. I think this is the only feature that might force me to a more expensive analyser. Thanks again.

Thanks for the summary video Kerry. For a future review can you look at some Wi-Fi signals? These will be at least 20 MHz wide and switching in time so the ultra mode algorithms should give degraded results. Would also be interesting to see the waterfall plot with Bluetooth hopping signals. Thanks again!

nice one

Super!!!

Nice Video Tnx. I only just discovered the existence of such a "Tiny SA ULTRA". Seems a decent tool. However, considering the limitations and the not so speedy reactions on the screen and the induced artifacts etc., would this still be a reasonable tool to be used on AM and FM radio alignment as opposes to a proper (but many many times more expensive) full size more respectable digital SA such as the SIGLENT SSA3021X Plus 2.1GHz ? I understand that the "SIGLENT tool" comes with a tracking generator as well but the Tiny SA ULTRA does not. Another question is do you happen to know what is the noise floor of the above SIGLENT for a range of UP to 150MHz? I'm inclined to buy The SIGLENT but considering the price tag....I'm not so sure. Thank you

Great review. Ordered one right away. Does it give an alarm when you get close to the max level for the input? Have ordered 30dBm attenuator for testing 100mW RC 2.4GHz TX.

For the price and size, performance seams excelent. You can do a lot more if you spend a lot more. BTW, Ilove that you used the FM Demoducaiton to listen to the local radio. I miss the days when I had a bit of downtime with the half a mil SpecAn so use to listen to the radio

what is the micro SD card good for? Does it record any historical data on the signal strengths it has seen (obviously without location)? This could be useful for someone looking to see if there are any devices broadcasting anything. That could be a tracking device. I know not all bad devices do send a signal. I am also aware that this doesn't capture any data but just shows a spectrum of wireless signals being sent.

That Toto Africa song gets everywhere.

Very nice video and test overview of this device. Thanks. I picked one of these up. I wonder though, can the signal generator be used to measure SWR on antennas at various frequencies to check antenna efficiency?

Can you use this to see what band people are using on Citizen band a.m. side band?

I would like to know how Tiny SA Ultra can be used to identify GNSS Jamming signals.

When looking just for a single spike in S.A. mode, how accurate is the digital frequency readout?

The listen mode is only for AM signals. There's no FM demodulation capability ,which is why the broadcast band sounds distorted.

I'm considering designing, 3d printing, and sharing a case that includes emf shielding for the TinySA ultra. It would have slots for metal of your choice. I'm new to the spectrum analyzer world, and wanted to protect mine but I don't know if it's worth the effort or if it would negatively impact performance while in the case, or perhaps make it easier to staticly charge the case and then accidentally esd the antenna. Any thoughts on this? Modeling it would not be the issue, I'm only concerned about causing more issues and dangers.

I've never heard of it being referred to as "modulation depth"...like a measurement of a null and not a peak

This device can be used to capture the 5 kilohertz frequency spectrum. if it is possible

👍👍👍

I wish the frequency range was usable on audio as well. Maybe with some THD calculations. It should be a much easier and less demanding application for its power

Good morning, sorry for the question, in the characteristics I read that AM modulation is optional, what does this mean? You need to add a card or redo the programming with the PC. Greetings

Nice for the price, but I wonder...doesn't it come calibrated ? I do not have a generator which goes above 1G

After making some changes to have optional segments of the frequency range settings load on startup, my unit now freezes on startup and I am unable to use it or make any changes. Any suggestions? If I connect the two internal pins, will that reset it or wipe the ROM?

We are interested in tinySA Spectrum Analyzer and Signal Generator. How to order ? The price ? Term of Payment ? Thank you for your early reply Robby Kaware

Checked with my HackRF and it was spot on, up to 6.9Ghz then it started to fall of, and at HackRF sigan generator output highest 7.250Ghz. it was quite off like -90Mhz or maybe it was more. but up to 6.9Ghz it was spot on my Ultra, and clearly the HackRF that wont play along above 6.9Ghz.. TheHackRF (H2+ with PP) was with the inbuild Mayhem signal gen. kzfaq.info/get/bejne/mLOegtd4nLiznX0.html 6.5Ghz sweep. kzfaq.info/get/bejne/obakfa1_zb2ypIU.html

What is its sweep windows frequency bandwidth around 1.6GHz? Can I monitor signals from 1GHz to 2GHz in one window?

Hey Kerry. You've seen me in the comments and answered me a few times and I (as I've come to learn how to sift the wheat from chaff) have come to respect your opinion as one who respects everyone's time and money, no matter knowledge level. I have a chance to buy one spectrum analyzer and use it to learn and still satisfy what I need as I learn more. What would you reccomend me buy as I plan to use it for audio, antenna building and testing after I get my operator license. I went through 4 scopes as I learned and as such ended up buying a rigol which can be stretched (if you will) to suit my needs going forward. I usually donate my old test gear so to get there I was out alot of money. I have a chance to buy an sa with tg and only want to buy one being the price is obscene even for the 12 year old rigol dsa815-tg. I'd like to have a full featured 6ghz model. I'd prefer to stretch the capability. I am 44 with a software degree from the 90s where I majored in search algorithms before it became an engineering degree. I never used the degree so it's useless now but I'm 44 and retired and have alot of time on my hands so I tend to learn quickly relative to average spare time people my age have for hobbies. I plan to start taking electronic engineering classes from a local school online next year to eventually get back to work when I'm healthy enough. I'm not concerned with money perse but I can't afford a keysight or rs box. I won't blame you if I make a bad purchasing decision in retrospect hahaha. Just looking for your learned opinion sir. I'd have hit the thanks button when I asked this if you had it enabled or if you do in the future I'll make good on pestering you wirh this long-winded soliloquy haha. I'd like to stay away from siglent as rcc electronics have burned me in the past and I've given them alot of business, relatively speaking. I usually purchase from electrometers here in canada. I have many hobbies but I'm not a maker. I appreciate the mathematical theory behind this, which is why I'm a dedicated hobbyist with thousands of pages of notes haha. Rf seemed like black magic but I have a cursory knowledge enough to inform the fact I'll outgrow a box that cannot be unlocked with software codes as I learn and need the added features. I appreciate your time and if you have pp listed I'll send a donation for your work.

Me again and another dumb question, why don't these SA's cover the audio range as well ? surely that would make them appeal to more people ?....cheers.

Does the tiny st ultra have a tracking generator?

7:30 Why are there sidebands at (+) and (--) 200, 300, 400, and 500KHz? For a pure 100KHz sinewave, AM, there should only be one USB & one LSB, at 100.1 MHz and 99.9 MHz. What does the time-domain signal look like on a 'scope? Since I assume the H-P S.A. can be trusted, the logical conclusion is that the RF gen. signal is distorted.

does this tinySA have a LAN port or something like that so I can access it using my notebook

Kerry, how can your tiny SA go up to 12 Ghz when all the ones for sale on Ebay just go to 5.3 Ghz?

No need to defend ham radio. Either you understand the technology and its advantages or you don't. Either way, it will never die off.

the version 2024 no is

We, people watching from outside the USA, don't know how much is 100 pounds 😂

Really groovy device until the antenna and headphones jack breaks. Garbage.

👍👍👍
