David,
? The tinySA also has an impressive RF signal generator mode with frequency and level sweep capabilities.? AM and FM modulation capabilities are also present.? The font size used in the RF generator mode is larger than the NanoVNA-F (I own one).? I guarantee you this little puppy will not seat away in a box if you later purchase a 4" version, because then you will want to use the smaller version almost primarily for tracking or CW generator purposes.

Re: Screen size #specifications

 

The regular tinySA has a 434MHz first IF and the low input is as listed in the wiki. Just like the old HP spectrum analyzers 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? (till above 3GHz) but the "signal identification" (just like on the old HP SA) is difficult to explain and I am not sure people will like it. So I do not expect this will ever be a product.
We are investigating other options but for now I suggest you go for a RF Explorer WiFi combo or something similar, but the display of the RF explorer is much smaller? than the tinySA.

Hi David, Good catch, will add screen size to the wiki:
All outer dimensions, screen size (2.8") and hard plastic enclosure will be identical to the nanoVNA-H
We are well aware of the demand a for 4" screen.
==================================================

Thanks, Erik. Based on past experience I'll be waiting for the more usable 4" version, as the original NanoVNA I purchased has simple sat in the box once the metal 4.3" version was available.

Thanks for pointing to the Wiki. I hadn't actually found that and I'm now confused over the frequency coverage. The Wiki lists two inputs 0.1-350 MHz and 240-960 MHz, and yet one of the posts I happened to find showed screen-shots around the 2.4 GHz region and talked of a 330 MHz (?) first IF. I was really hoping of a unit covering the 2.5 GHz region (for QO-100).

Screen size #specifications

 

I've just joined the group but despite searching the messages I don't see a screen-size specification. I do hope that a 4/4.3-inch screen will be available, as that would be the minimum I would purchase. Ideally, of course, sold as a boxed unit with battery, or one which only requires a couple of screws for assembly so that it is classified as a kit.

Thanks,
David

Larry,

I agree with some of your comments. But I can tell you for portable use the 4" is much better. Also I take some offense to the comments on hams. I have been licensed since the 1970's and spent all of my career in electrical engineering designing all types of electronic devices and T&M equipment. I can assure you that I know what a spectrum analyzer is and does, just as sure as there are many hams that know the same as they started their engineering careers due to their interest in ham radio.

I personally know dozens of hams that are excellent RF engineers and know their way around an RF lab so for you to make such a careless general statement is harmful to the fraternity.

Sure there are "lids" that are hams just as there are in general society. So instead of lambasting them, how about taking on the task of educating them so they will understand how to use their TinySA?

If Erik is able to keep up with the demand perhaps the volume of sales that you predict will allow him to further improvements and/or new future products.

In the end we will all benefit.

Sincerely,
?

Kudos. I also am anticipating rollout as a spectrum analyzer is exactly what I need. I've tried RTL-SDR dongles and it doesn't give you a "big picture". Especially when we are going after interference that we find "walking up and down" the band. Same with CABLE leakage. and here in the US, that's a problem.

I also think you're conservative approach to the 2.8" vs 4" version is appropriate. I did buy a 2.8 NanoVNA then "had to have" a 4. I have used my 2.8" 10 times that of the 4".?? Because on the bench the 2.8" is attached 100% of the time now to a PC..? Being able to capture, view, store and print graphs plus using my mouse that I'm accustomed to after 20+ years of steering one. I'm happy.?? Both the 2.8 and 4.0 are hard to read in direct sunlight. cardboard boxes help. Who does not have a computer, tablet or smart phone for a bigger display these days?

Finally, although selfish, I would hope and I'm sure all on here would agree, that you allow your followers 1st crack at the release production run, 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.

We first have to ensure the device passes all the user and manufacturing tests. Only then production and selling can start.
Progress is good but the past has learned us not to promise a date.
W.r.t a 4" version. Only after the 2.8" is a success and sells in "sufficient" quantities next steps will be considered.
Locked Re: TinySA introduction video

 

Any idea when these will be available?
a 4" screen like Hugen's NanoVNA H4 would be a huge seller having owned both the original and now the 4" version, the 4" one wins hands down!

Very impressive. Looking forward to purchasing one for use on my bench as a test and measurement device. Looking forward to follow on products.?
Is there a product roadmap anywhere indicating thoughts on future offerings?
E.g. more frequency coverage,?
I am new to the group, but is there any kind of documentation available such as functional block diagrams or preliminary schematics or if it is open source?

Very impressive for the target price.

Yes, an AMAZING number of features, some of which I have never seen on any other spectrum analyzer.? The tinySA has features that are optional on my Siglent, and the Siglent option package costs about as much as 8 or 10 tinySAs.? I'm keeping my Siglent, but the tinySA will definitely also get used, and when the 4 inch version comes out, I will buy one of those, too.

Yeah, the screen is a bit small for these old eyes, but I have glasses and a magnifier, and for what my Siglent SA cost me, I could buy a truck load of magnifiers to use with the tinySA.? I will use the tinySA with the same glasses and magnifier I use with the NanoVNA.

============================
Dave,
? ?It seems like a short period of time but Erik has been perfecting the design for months now starting with your homebrew version.? Combining the original design with features from the NanoVNA and additional generator operating modes makes the tinySA feel tiny only in size.

?I own a HP8558 spectrum analyzer which covers the same range as the tinySA and also covers more than half of my workbench.? The tinySA gives me far more capability and the HP8558 is a pain to keep working.? Like you I value my bench space, so because of the tinySA my HP8558 is being donated to the local technical high school.

?Since you are familiar with Erik's past work you know how meticulous he is.? I've worked with a lot of engineers in my career in EMC but rarely any that combine Eriks hardware, software and firmware skills.?

Locked Re: TinySA introduction video

 

I like the small size of the NanoVNA and also this TinySA.? Small means easy to fit on my cramped bench along with all the other paraphenalia and whatever project is on the go at the time.? Having a built in battery makes it even more convenient.? Small size also means lower price which I think is important.

If I want a bigger display with more points etc then I hook up the NanoVNA to a PC.? Don't have a TinySA yet (I do have a homebrew version of Erik's original design using different processor with WiFi and webserver to PC, smartphone or tablet for bigger displays, but so far fewer features) but will sure get one if the price is right.
Fantastic development effort by Erik in a short time period.

Hi Herb,

I already thought the screen looked very usable. I have used a big, mil-spec SA and I have been missing having one. I will be watching for the sales announcement here and order right away. I am excited about it.

The nanoVNA has exceeded my expectations. I am sure the tinySA will not disappoint.

Bill,
? ?hugen's philosophy is to give students, ham operators and enthusiast access to test equipment at a sub $100 USD price.? I believe he is targeting the tinySA at a price point closer to $50 USD than $100USD. At that price you can use the 2.8" tinySA and explore its capabilities until the 4" version is released.? I doubt you would have any problems selling or gifting the 2.8" version.
? ?Additionally, take a look at the following screen shot for the rf generator mode of the tinySA.? It is more legible than the fonts used on the NanoVNA-H4 and I would want to keep the smaller tinySA just to use as a companion rf generator for the 4" tinySA.? The two together will form a nice 100k-350M tracking generator set-up. Frequency sweep, level sweep, AM and FM modulation schemes in the LOW OUTPUT mode particularly make the tinySA useful.? I suspect some users will purchase the tinySA just for its signal generator capabilities.
Erik has really packed a ton of features into the tinySA.? His attention to detail and quality along with his partner ship with a respected supplier like hugen are enough to make me want to add the tinySA to my toolkit.
