Re: tinySA has been listed in Alibaba store

 

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

Re: tinySA has been listed in Alibaba store

 

Congratulations.??
I too have placed an order.? Thank you for posting on the Groups.io board.

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

Re: tinySA has been listed in Alibaba store

 

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.

Erik and Hugen,


congrats on getting this to this stage. My order is in.?

And here you can find all the product details:
tinySA has been listed in Alibaba store

 

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.

Re: Screen size #specifications

 

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:

Re: TinySA as bandscope

 

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.)

Here are the bandscope pictures using this fast scanning (the indicated scan time is still the old scan time)
There is still a small bug in the fast scanning causing the frequencies to be off by one RBW as you can see in the digital band under marker 1.
The markers are tracking markers marking the 4 strongest signals and updated every scan of 0.5 seconds.

No to add fuel to the fire but I will quote from your initial email below.

You are the one that spoke, in no uncertain terms, about hams in general, not I, and everyone can see that. I did not do so.

You can stand by your statements, which in my opinion sounded to me to be self serving.?

I did not admonish you, that was not my intention but tried to point out that there are certainly hams that are as smart as you or I, and know their way around RF.?

I am sorry that you mis-interpreted my response. Based upon my experience, of the hams that I know they have a thirst for knowledge about many things. I would think that is a good thing. So what if they?want to buy a product that they may know nothing about.?

With the fraternity decreasing in numbers we need all the support that we can get. Don't you remember when you knew absolutely nothing about spectrum analyzers, or were you born with the ingrained knowledge? I'll bet?certainly?not, you had to learn all of?the?details one way or another.

I am sure that sometime in your life you asked what others thought were "stupid questions". I certainly have So I would not have made a general statement as you did below. Perhaps you should have phrased it differently.

"as the second something new comes out, the pig herd (hams) will run out and want one and they can't even spell spectrum or analyzer. In the USA we have a comment regarding them, "more money than brains"? In any case they will deplete units on the shelf, then bombard? the group with stupid questions. The downside to your journey to fame and fortune."

So let's just "bury the hatchet" and part friends. I am sorry if my direct response?offended you. I consider the subject moot.

You could always make it an option, just for us geeks.

when you remove the input low pass filter you can do all kind of tricks like harmonic mixing. I have the SW to show it is working?

Some of the more geeky types here - looking at myself - would be interested in that.? I remember doing the signal identification stuff on an HP141T.

I own both the 2.8 inch and 4 inch versions of the NanoVNA H and I can tell you I like the 4" much better. From R&L Electronics the 4 inch is only $10.00 more than the 2.8inch (about the cost of two cups of?coffee?from Starbucks). Well worth the extra. If Eric could work out something with Hugen and his source for the enclosure used for the NanoVNA H4 the pair of them would be a great combination.

This is coming from someone who has repaired or used RF test gear professionally for over 40 years.

Given this can be paired up with a laptop or PC with a much bigger screen (Just like the NanoVNA same form factor) I am not sure a larger screen size is the way to go. For sure some might need it but not everyone.
It might move it to being far too costly if it defaults to have 4"+ screen especially if you don't use it.
