Nice!

I will put an order in. I am collecting Nano projects like I collect radios. :-)

I look forward to seeing where the project goes from here. Maybe a V2 or a H4? Maybe a combination of the Nano VNA with the Nano SA built in one package?

Many thinks to both of you for the project, and continued support of them, great for experimentation.

Dear community enthusiasts, we have manufactured a small amount of tinySA for sale and now sell it through the Alibaba store. If the community feedback is good, we will make more. The current logistics speed is slow, and the logistics cost for sending to some areas may be higher. If you don’t wait to test it, you can wait for us to manufacture it in large quantities and distribute it to overseas distributors. Purchase to save logistics costs.


Many thanks to Erik for creating the tinySA project and implementing it. Many thanks to the tinySA test group enthusiasts for providing great feedbacks.

Erik & Hugen...
Congratulations on bringing the project to this stage.
I am wondering if there is a 4" variant in the works, or even at ambition level.
Unfortunately my eyesight is too poor to be able to use the 2.8" comfortably.
Well done to all involved!

Dear Hugen and Erik K

Thank you very much for this product.?
Mine is On Order.
Looking forward to "beating it up", and further products.

All the Best

I posted the following on the NanoVNA groups.io:

"hugen has released the tinySA spectrum analyzer at . The tinySA joins hugen's stable of products targeted at radio amateurs, students and electronic enthusiasts. It fills the gap for NanoVNA owners who have been trying to use the vna as a spectrum analyzer or signal generator.

The tinySA was developed in conjunction with Erik Kaashoek a long time member of this group and an outstanding designer/programmer. At $50, not including shipping and handling, its a no brainer for hobbyists looking to expand their measurement capability on a budget. You can find all the product details at:
"
? ? I had the good fortune of receiving a beta version of the tinySA and it has definitely earned its place on my test bench as a sub GHZ spectrum analyzer, with its own display, and built-in rf generator.? Because the tinySA's display is not as busy as the NanoVNA, the 2.8" diagonal dimension works out pretty well for me - and I wear glasses. If the 2.8" tinySA is successful enough for a 4" tinySA to be produced, then your purchase of the 2.8" tinySA will not be wasted because you can use it exclusively as a very capable signal generator.

Thanks, Order in.

Been following the progress over on the NanoVna board and when I saw Hugen's announcement,
well just had to get one too..
Can't wait to try this device!
Thank You so much for all the hard work and much success going forward.
Cheers
Colin

Congratulations.??
I too have placed an order.? Thank you for posting on the 开云体育 board.

At this price point, I am sure the project will be successful.

I also have ordered one. I saw that shipping was the same if I? ordered 1 or 2. If I had another friend that wanted one, I would of ordered 2, That was not the case here. But others may want to "group" buy..

Thanks for the product. Looking forward to using it..... especially to track RFI.

Valid point, Dom, but counter to that, I like self-contained devices.
If the option of a 4" screen was available, that would be my choice, even if it meant a few quid more.

Fantastic.? Are you able to share how your fast frequency schema works?? i would like to try it out in my homebrew version!

I wish you a lot of patience.....

While we were busy changing the unit letters we also change the u to the greek letter, probably too small to see the difference on a 2.8" display.

Right. If you ever need the authoritative source:

ISO 80000-3 — Quantities and units — Part 3: Space and time


(Scroll down to 3-9.)

Most ISO standards cost money, but the "Terms and definitions” sections are usually freely available. The authors of ISO 80000-3 managed to get most of the meat into that section…
Too bad that the authors of IEC 80000-6 (which has the electrical units) didn’t.

A good secondary source, from a veritable horse’s mouth:



Or, shorter:


(I just happen to be somewhat loaded up on this subject at the moment, see RFC 8798 if you want to know why.)

Grü?e, Carsten

According to Wikipedia and other sources its 's' so I replaced 'S' with 's'

And when there is a small 's' letter, your problem will be very small and you won't see it on the 2.8" screen. Bravo

Erik, please leave it at that, if only one person in Siemens thinks about it, it's still acceptable.
Otherwise, the difference between the big 'S' and the small 's' will be so minimal, at least it WILL SEE.

I’m not asking for a small letter, but the lower case letter s that has been the symbol for seconds for a century now.

A capital S is also easy to mistake for a 5, and it blends in with the number that is preceding it. Even if there were a valid opportunity for choice, S is worse than s.

Since kHz and dB/dBm are already spelled right and very visible, the above is a *very* weak argument.

(Fortunately, there are few descenders here — that would be an actual problem, and that’s why it is quite acceptable to go for u instead of ?. If I actually were a purist, I would also note that there needs to be a space between the number and the unit, but I won’t.)

BTW, please do not use S, the abbreviation for Siemens (conductivity) for seconds (time), which are abbreviated s.?
