Great video, just In vhf the S-meter S9 is arround -93 dbm

[SussyDubby]

These devices are amazing, people don't realize how advanced this is for the price. 10 years ago tech nerds would cream over having a functional spectrum analyzer in the palm of their hand.
I have one of these, they are S tier.

I'd advise anyone buying this to get a replacement set of connectors, and some extra female to male, male to male, and female to female connectors to attach the unit itself (AND some short jumpers) to "save" the ones on it from wear and tear, AND because you ARE going to loose them and drop them, etc. And BNC to sma adaptors and BNC ones too. Also, if you are considering obtaining a full size spectrum analyser over this one? DON'T. instead? Buy THIS ONE FIRST along with the Tiny VNA. Trust me, sure the display is small. But you can't beat the portability and price! It's incredible that you can place a DMM, VNA, SA, and digital tiny scope into a shaving kit bag: Do just that, and these instruments become your EVERYDAY CARRY instruments that you actually USE. AND? It all runs independent of the mains so you get rid of ground loop problems. After you take these steps? You just might forget that you need an expensive VNA and SA, or NOT... But if you do? You'll have THIS fine unit AND interchangeable connectors at the ready for you larger unit! ;-) All the Best! 73 DE W8LV BILL

Thanks for taking the time to make such a concise and informative review of the TINYSA ULTRA. Looks like exactly what I have been searching for!

[qzorn]

Wow this is so interesting. I am learning how to put together, setup, and test a hydrogen-line 21cm (1420.4058 MHz) SDR radio telescope dish. The TinySA Ultra spectrum analyzer is one of the recommended test equipment items. Now what? This video is just what I need to understand what it can do. The R-scope is all new to me. 😎 Thank you.

[DennisMathias]

Wow. What a great real world demo! Thanks for going through this clearly. I of course have to have one now.

[allancopland]

A very interesting and inexpensive piece of kit. Thanks for the review.

[antennafarmer]

I applaud screenshot capability as we have been needing it for a LONG time, but we really need it on the nanovna.

[Jonnyweareten]

Great video as usual, gotta get me one of them!

Hi. Thank You for interesting video. I have just obtained my Tiny S.A ULTRA and played a little. Before I had previous version, but wasn't fully satisfied because ow it's RBW limitation to 3KHz. It was impossible to observe basic audio modulated signal lika AM or SSB, but ULTRA model is improved to 1khZ AND 200Hz which allows that. I also plkayed with it as signal generator. Measured output power with chinese small power meter. Results are satisfactory. I subscribed to Your channel and looking forward for other cool videos. Best regards. 73 Marcin SP5IOU

The whole point of the pin number was for the users to read what is written on that page 😀

[dougbas]

Thanks. Goint to recommend to my HAM club members.

The audio out is primarily AM demodulation. FM is recovered using slope detection.

Pro tip:
"dBm" is a power measurement (ref'd to 1 milliwatt) where 0 dBm = 1 mW
"dB" is an attenuation value where 30 dB is a power attenuation factor of 1000.
End of Pro tip.

[GYTZ]

I think those harmonics might have been due to overloading the input to the Tiny SA. 30dB attenuation is probably not enough as the maximum quoted input level is the damage level, not the working input level. The easy way to tell if you are overloading your Tiny SA (or any spectrum analyser) input is to add an additional 10dB attenuation, if the harmonics drop by more than 10dB then you are overloading the Tiny SA's input pre-amplifier.

[thetechgenie]

The fact that it has demodulation and frequency generator and seem to be decent. I going to buy one to try it as have portable spectrum analyzer that cost at one point 38k and still around 19k refurbished for one it a real time spectrum analyzer. Obviously don’t expect to see I be near the performance but also did repair recently a older rohde & schwarz fsh 3 spectrum analyzer that had a bad FET as won’t turn on and bad battery which replaced and now works so wonder how it hold up compared to that one? For $130 don’t expect it to but if it come close and usable it be a steal. Also interested in how well the signal generator is and quality of signal?

[spectralcodec]

So cool! Does anyone know if there is an API to talk to the TinySA with custom software?

[RESISTAGE]

original unit sold on aliexpess ?
made my day.

[williamduncan]

Your attenuator is 10 dB with 10 W max operating power. You're not doing 30 dB attenuation externally. Even with a 5W transmitter, you need at least 37 dB attenuation to bring the power down to 0 dBm (= 0.001W = 1 mW) which is the recommended for the TinySA input.

Great video. I have just ordered one. Cant wait to get my hands on it. Thank you. Mark 2w0jmk
