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.
Bravissimo! Heartily concur!

Holy cow, that stuff was around 100k in my radio workshop back then 35 Years ago 😁
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 !!
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.
It appears to have a better noise floor than the previous one, nice.
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. 😀👍
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.
Your video was very helpful, I decided to buy one as a result. Tnx es 73's.
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!
Ordered one from R&L; they had a initial 90 units that sold out so I'm in the queue for their next shipment.
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
what a fantastic device thank you for showing it to uss
i must have one, as always...
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.
make sure you watch: th-cam.com/video/djhrmAFfPns/w-d-xo.html
Very nice. Thank you!
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.
Outstanding thank you.
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
How do you know the noise floor on the HP, is it on the HP screen, is so can you point it out, please?
nice TinySa-ultra video. 🥳 In setting setting up a DIY 21cm 1420 MHz SDR radio telescope dish this little analyzer was recommended. 🧐Now to figure out how to use it. Thank you.
Technology really has done some amazing stuff.. I could even dream of affording one of these.
Phenomenal!
I saw the 1 MHz carrier at the left edge in the 1 to 800. MHz mod, it was where I expected it. They provide a pick for the screen, using an abrasive eraser will scratch the screen way quicker than the pick. Ron W4BIN
my Japanese pencil has a soft non-abrasive eraser but point taken. I would not use a standard red eraser
i am waiting for mine
i ordered one a few weeks ago because it measures much higher in frequency than my 1.5Ghz Siglent
Well it just figures. LOL 😅😂🤣👍
I got the Tiny SA last spring (ish) and now this Ultra version. LOL
Oh well. I will say, this thing has turned out to be very useful.
I especially love it when I'm tweaking our antennas.
I got my TinySA *last week*! Oh well, it's not like the Ultra is only $10 more, it's over double the price.
Hi m8, a bit off topic, but can one of those portable Earth Leakage protected orange power boards, the ones Tradesmen use be better than nothing when working with high voltage devices, say a CRT Oscilloscope?
Could it save your life?
Cheers.
Seeing the compromises in Ultra mode will be interesting.
just posted new video
16:07 noise is Bandwith dependent. It is not good comparison between 3MhZ and 850kHz.
Wow! Sure wish I had this when I was walking hospitals and piers instead of my Anritsu!
This looks very interesting. I wasn't sure how good it would be but it does appear to be useful despite the low price. Can the cal output be used as a tracking gen?
no. you can use an external source and a mixer to fake a tracking generator from the IF output. I have a video on that
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.
Bought one from the recommended Aliexpress store on the tinysa site. I figured trying to buy one in the US would be futile. Thanks for the headsup.
What is the recommended AliExpress store?
I have a Tiny SA and am thinking of upgrading to an Ultra. I'm mainly interested in using it as a signal generator. I've read that the minimum o/p level is -123dBm but elsewhere I saw -153dBm. Is there a selectable 30dB attenuator option?
Thanks, Mike
Great 👍
I must try this...
I bought a Chinese RSP1 clone for 15 USD and it works great with the Spectrum Analyzer program from SdrPlay. Yes, TinySA is standalone, but it’s still hard to work on such a screen, and it makes no sense to buy more expensive ones on a computer.
And the RSP spectrum analyzer sweeps MUCH faster even at narrow RBW settings.
When I was in college, it cost $25,000 to be that slow
I'm so happy with my Signalhound with 1 Thz sweep 🤠👍
but this one has an LCD screen! 😎
Hi
could I use it to check wireless microphone transmitters and receivers?, they work from 470 Mhz to 950 Mhz., 50 mW, 100mW and 250 mW
yes, but only with telescope antenna it comes with or use of an attenuator: th-cam.com/video/2dKaHbvb7GA/w-d-xo.html
Just a short important notice. Whenever you connect the TinySA to a transceiver FIRST DISCONNECT the mike. I already toasted one's front end, accidentaly pushing the PTT with my belly, having the mike on my lap.
gotta loose the belly .
😂
AW, CRUMBS...(!)
order placed
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? I know there is a couple of upgraded ULTRAS out there, I've seen one on a TH-cam video and there's a couple on Google images of individual users.
only buy from here: tinysa.org/wiki/pmwiki.php?n=Main.Buying
the original tinysa had an issue and ESD diodes were added on newer units. the ULTRA is already a different design. I recommend you buy an ultra as it is a better unit. as far as input protection, be vary careful with these little units, the inputs are very fragile.
@@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 looks pretty good at that price.
@20:54 - HP is claiming -36.8 and the tSA is saying -35.7
Pretty close... the RBWs are not matching though so its tought to do an exact comparision.
The tinySA is reaaalllly slow though! Needs a faster CPU :D
Cheers,
The CPU is most likely not the bottle neck. I mean you are comparing a 120USD device against one that costs a multiple of that even used and old. So I would say it is doing more than fine ;)
newbie question: would this device be able to view/monitor CATV upstream spectrum 5mhz-52mhz?
yes
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.
Is the procedure for using an external mixer as a trace generator the same as the previous model?
it no longer works due to a new architecture
@@IMSAIGuy what a pity, I intended to buy it to use with my tinysa to do tracking, anyway, thanks!
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 TH-camrs 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?
Yes, you comment on the password is correct. I had Erik add some words to the wiki describing the high Lo leakage to the RF input connector. He refused to add that it is -10dBm which is way more than just simple leakage in my mind.
@@IMSAIGuy, definitely. We're hoping for $120 HP analyzer, but we get a $1500 analyzer for $120. I won't cry.
He reads 100. kHz as 10. kHz. If he continues to use that pencil eraser to operate the "tiny ultra" the abrasives in the rubber will wind up scratching that plastic screen into foggyness.
That is why the manufacturer included that guitar pick in the tool bag.
I don't understand why he didn't compare some FM radio station's signals and what the jumping modulation does to the displays. 88-108 MHz. Ron W4BIN
Japan Mitsubishi pencils have non abrasive erasers. I have lots of other videos, check out my playlist 'tinysa' this was a first look as the description says.
Is it capable of accurate frequency measurement? lets say 1 - 5ppm in 10 - 50Mhz range?
read the wiki: "Frequency accuracy equal to the selected resolution bandwidth"
@@IMSAIGuy I am not qualified to read it properly (: only asking because I am not familiar with spectrum analyzers in general and looking for a tool to learn analog electronics with. All the details in specs look confusing at this point and OFC I'm not able to differentiate marketing from real-world characteristics of instrument that I need to choose for a start. I figured that something like a $1000 Rigol is a good value, but it is certainly steep as I'm not that involved in frequency domain yet.
@@Mr.Leeroy I assume you have a good oscilloscope. that is first. spectrum analyzers are more of an RF tool not analog electronics. and if you have a good scope it will have an FFT spectrum analyzer function. The TinySA ULTRA is a good start if you have the interest in RF. I like the Siglent spectrum analyzers if you have >$1000. here is a beginners look at spectrum analyzers: th-cam.com/video/Ze4V6Qp1mK8/w-d-xo.html
FFT: th-cam.com/video/JbZ1-qFaVG4/w-d-xo.html
@@IMSAIGuy Thanks for suggestions. I've got DS1054Z, pretty happy with it. You tell me if its FFT could be called pretty good. I hear that it is very limiting. I'm not particularly interested in SDR or FM/AM right now, but interested in learning (or at least attempting on an amateur hobbyist level) RF circuits for common digital protocols. Something like PCB antennas and RF routing for WiFi / BLE is what on my mind. But at the moment, I am doing my designs around RP2040 chip and even verifying 12Mhz oscillator performance (as in being able to fine-tune frequency to datasheet spec, adjust drive level, measure oscillation margin) would be good to be able to do. I still miss GPSDO standard probably.
@@Mr.Leeroy fft on that one is not great like this: th-cam.com/video/ZHYmUS7R6V4/w-d-xo.html
All the tiny SA Ultra's I can find on AliExpress serial numbers all start with SU. Are they all fake?

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.
yes, you can set RBW and VBW manually
At the beginning, I think that you meant "wider" rather than "faster".....

I wonder if is similar to NanoVna-H4 ?
no

Thank you Google for suggesting this video... Don't have a clue what this is or what the man is talking about.
Try a terminator on the cal sma!
what would that do?
@@IMSAIGuy Open connectors are a source of leakage and signal ingression. This is especially true with RF, so the rule of thumb is all unused terminals should be terminated. I am sure that the noise floor and signal display would improve if a terminator was installed.
I have an old HP spectrum analyzer that has the IF output on the front and yes you always put a load on it. I tried it on the TinySA and it does nothing. different system design. There is a internal switch that disconnects this port under normal sweep.
@@IMSAIGuy Well at least you tried, still it's good practice.
Another thing that could possibly help would be to ground the SMA, just use a jumper to see...
I have an HP 8566B and I can't lift it.
but ain't it glorious
I think i over paid for mine
The noise floor comparison showed about 15dB difference. This should have been expected as the RBW of the HP was at 3MHz and the RBW of the TinySA Ultra was 850kHz. That's a difference of about 4 to 1, so there should have been about 6dB or so difference between the two. Not sure where the other 9dB came from.
I think the tiny defaults to having an internal preamp turned on

What the hell do I do with this thing
I explain analyzers: th-cam.com/video/Ze4V6Qp1mK8/w-d-xo.html
The test did not say anything of vbw or rbw shape. Not the somewhat not logical menue structure of the tiny sa. Learn fully how to control your HP analyzer with sweep speed, internal attenuator, delta markers etc. and set up the tiny with the same setting (you have to invoke manual settings). Good luck.
other reviews,,not so good
I would like to see other reviews of the TinySA ULTRA, where did you see them
What the heck is this damn thing
It's a spectrum analyser.
Why are you talking to a box? LOL.
