I’ve owned the original TinySA for a while, and in that time I’ve found it invaluable from a hobbyists point of view. I’ve preordered the Ultra primarily for its increased frequency range. I use a lot of 5GHz devices and to monitor them I’ve relied on my HackRF1 and a PC, this Ultra will permit a much simpler work flow, especially when out in remote locations.

Can’t hardly wait to get one of these! Awesome upgrades! I think I will greatly appreciate the bigger screen!

@BigEars2011 @rickeaston3228 Gheesh people. The man spends his own money on equipment and his time on setting up and presenting this material without asking us for a dime and you have the gall to criticize him for not creating a professional quality presentation. If you want "Reality" TV slickness then break out your wallet and send the man some cash so he can hire script writers, directors, camera operators and such. Personally I prefer this unscripted first look over a professional presentation as the real part of reality comes through unfettered.

I know what speak of!!! hi hi!!!

Thank you for the information one month before Christmas. To try out my spectrum analyzer I bought cheap microwave motion detectors in the range of 5.8GHz, 10.525GHz and 24GHz which serve a simple sources and receivers. The motion detectors can be tuned (slightly) by the supply voltage and one of the the 24GHz modules even has an internal divider to measure the frequency with normal instruments at 3MHz. Together with LNBs receiving at 10GHz and using harmonics to reach their input range one can play around in the frequency range with tubes, resonators and shields. (Of course with limited power.)

Thx So much for doing this video !! Your review "Style" is perfect for folks like me learning how to use these New & complex affordable Rf test equipment....Your "How to Use" NanoVMA & this video are Immensely Helpful & vital for me so much so, I bought both !! Thx again & keep 'em coming !!

It appears to have a better noise floor than the previous one, nice.

Point of order: at 16:30 the HP would have 10 dB better NF if you removed the 10 dB of attenuation that is normally switched in. The SA Ultra apparently does not default (nor include in the specs) to any input attenuation when initialized, whereas the HP does. Fellow HP 8591E owner BTW. And thanks for the video too.

I've been waiting to pop on one. I was lukewarm on the original TInySA. Thanks for being the "guinea pig" for the rest of us.

Great review!

Awesome! Looks like another stocking stuffer on the way. 🙂

I just went and ordered one from R&L before this crowd watched the video and bought them out. :)

Thanks for the honest review. Am getting one. Woooohooooo! Thank you.

Very nice. Thank you!

Your video was very helpful, I decided to buy one as a result. Tnx es 73's.

Oh man, I can't wait. Thanks for the review. I loved the original but I wished it had a larger screen. Hopefully the tinySA MEGA has a HDMI out. :D

This is the first I ever had but I found it very useful and as usual I watched your videos on using it, I don't know how long I have it, I thought it was longer than 8 months but maybe not anyway thanks for your videos and take care of yourself great work and Cheers... Jim. 😀👍

Ordered one from R&L; they had a initial 90 units that sold out so I'm in the queue for their next shipment.

Outstanding thank you.

what a fantastic device thank you for showing it to uss i must have one, as always...

Phenomenal!

I haven’t seen the other tiny SA videos, so when I saw the gold foil logo on the box, it made me think there was going to be tiny chrome knobs and stuff. 😂 But this is much more practical.

OMG, I've been working on some amateur radio stuff in 5.8 GHz and have been desperate for an SA. Thanks for posting the video, this thing wasn't available last time I shopped for one.

It's over twice the price of the original. For a very casual user like myself the original TinySA is fine. Although it would be fun to hunt for Wi-Fi and 5G signals and whatnot.

neg 80 is getting close to the noise floor of roughly -120db. most decent recievers are right at home -30 -40, a good point to point ten years ago could run full modulation and passing ber test -26--32, our pathing boxes could pick up path at -110-12ish. just wanted to illiterate for the listeners anything below your rx threashold is two birds in the bush, above threashold and that birds in your hand

I've seen the latest 2.8 screen versions listed as "Upgraded Version: ESD Protection Diodes" the frontend load ratings are lettered on the front as +10 dBm 10 VDC Max. I see listings for the Ultra (4'' Screen) that state the higher load ratings on the front. I know one US Seller had the higher rating front end image posted on their store site but have changed it back to the image of an Ultra with +6 dBm 5 VDC Max. " Would you know anything about this? or is there any hearsay circling about upgraded ESD protected Ultra units looming in the future?

@@IMSAIGuyYes, very delicate. Wiki page suggest not to operate without 30 dB pad. There are a few Ultra Images online suggesting a higher durability +10 dBm and 10 VDC front end limit. I'm going to wait and see if those start popping up into circulation. Tnx!

It appears they mandated people go to the website to get a 'password' in order to force them to read about what the limitations were of the Ultra mode before they enable it. The designer clearly understood that there are many KZreadrs who don't know what they're doing who would buy one of these, never read about how to use it and what its limitations were in Ultra mode, then do a video badmouthing the units because of the trade-offs that have been made in order to create a $120 SA that displays frequencies in the multi-GHz range. I think the designer was very wise for doing that, and I'm quite pleased with my Ultra that arrived yesterday. The only thing that bothers me is that it has so many features I have to learn how to use. :) BTW, the rudimentary PC software they have available to run with it has multiple sample-averaging you can use to help kill noise. Of course, that slows things down, but for $2, who cares?

Noise floor comparison is not fair because: The reference instrument had a 10dB attenuator inserted, the smaller instrument had no attenuator. The reference instrument had a faster sweep than the smaller one. Do do a comparison, the attenuator and the sweep settings must be the same. BTW, even if it cannot compare to a real spectrum analyzer, this is still a very good instrument.

2.4GHz to 2.5GHz is what interests me.

If it's like the regular one, which I just got, you can set the resolution bandwidth manually. A quick way to get to the menu to do so is to touch the spot on the display where it's shown.
