Make sure to run selftest!

just? delivered. Nice.

DHL added (to UK) ?21.36 vat etc.

Quick check with a few sig gens and certainly responsive.

1: Is clear. It will depend on available memory. Not sure yet
2: Occupied bandwidth is clear. Specify center freq and channel width and calculate the power inside and outside channel. probably use maxhold to get the curve.

Can you give a bit of background on these

Erik,
?1.? I would envision the editable transducer factor table being similar to your level correction table.? The main difference would be a menu option allowing the user to enter up to 9(?)? freq/value pair that are added to the displayed values as conversion or correction factors.? There may not be sufficient memory in the firmware to allow this with all the other features you have provided.? The other problem would be changing the display units, if say, the factors converted units from dBuV to dBuA.? Maybe something to consider adding to TinySA.exe instead.

2. The automated occupied bandwidth measurement is a feature one of my club members demonstrated on Siglent spectrum analyzer.??Occupied bandwidth measurements are used to measure the power of the occupied channel as a percentage to the power of the channel.? I 'm not sure what algorithm was used for the measurement. Jim Allyn?has a Siglent specan and might be able to shed light on the measurement procedure.?

???? I have a Siglent spectrum analyzer I bought recently, and the tinySA has features that the Siglent doesn't have.? I can add some of those features, if I want to spend 500 dollars to purchase the firmware options.? Erik has done an amazing job of adding features to the tinySA!

To all
Feel free to continue suggesting improvements. Sometimes I need feedback from multiple people to spend time on things that are useful but I'd rather avoid (such as updating the wiki, or changing colors of items on the status panel)
The feedback and requests from the beta testers have been tremendously useful.
W.r.t discussions started by suggestions, I would kindly request to "build" on suggestions e.g. improve on them.
Any suggestion is a personal view and has to be respected even if it seems ridiculous. If the latter, simply ignore.
I may react to requests or not. Don't read anything in me not reacting. I may be busy.
If you are (repeatedly) requesting something and no other people build on it, it may be something relevant for you, but not (yet) for the broader community. Which is not a problem, just something to be aware of

Hi Erik,

I wish that if what you've created isn't good enough for them, they'd stop grumbling and go and produce something themselves.

I wish that people would show the gratitude that the work of you and the team deserves.

? ? A wishlist is not a demand, nor does it show a lack of appreciation.? I worked with Erik on the beta team and he knows I have the highest respect for both him and his work.? Erik is next to brilliant when it comes to squeezing features into the tinySA and has always welcomed suggestions that help the tinySA distinguish itself from the crowd.? If a requested feature isn't possible or lacks merit, he will not hesitate to let you know - and in most cases explain why.

? ?If there are no additional features you think can help to improve the tinySA then I'm happy for you.? If someone else makes a suggestion that they believe will improve the tinySA's marketability than you should leave it up to Erik to decide if the suggestion has any merit, and not assume the person making the suggestion? is "grumbling or showing lack of appreciation".

I used the tinySA to debug dbv-c signal quality on my cable distribution. Easy to spot bad splitters or overload due to amplifiers

Thanks again EriK. I can't see how he can do it, but the important thing is that he does it. 30dB is not a panacea but it is pretty good. In a TV antenna installation the decoding will be satisfactory with 30dB C / N ratio and normally we will not find much more than that. Therefore, we could use the tinySA as a "poor man's field meter" for amateur use, with portability and value for money, unbeatable price.
Congratulations

To Eric and Dave, and others,

As an amateur and hobbyist in radio and electronics for 60 years, I?have?spent thousands on professional kit in the past, played with it, learned a lot but it has mostly lain idle for the last decad or two for lack of benchspace and time.

If I was honest, I doubt that I could get better results below 300mhz from all the professional stuff that I could not do with the current Tinysa, with the exception of ssb imd measurements (for which I can use a ?15 rtlsdr or rsp1). I could not walk around with a boatanchor for tracing qrm/qrn either.

The arrival of the nanovna family and Tinysa will transform my hobby. As I have said in a previous post, a uhf- only (300-mhz to 3ghz) version of the Tinysa would allow me to also play with low band wifi, newer phone bands etc.

Erik, on behalf of a silent majority, thank you for all your dedication in producing something pretty amazing. Whatever the limitations of the Tinysa, it's far far superior to not having one.
Regards and many thanks Dave.

Nope, its fixed DSP inside the a chip

Is that high input mode mirror supression “ tweakable”, (eg with a balancing variable capacitor), or tiny twists of enamelled wire?

Steve, ?G7PSZ

In high input mode there is some amount of mirror suppression, at least 30dB.?
Not good but usable for certain measurements

Thank you very much Eric, for your quick and efficient response. It looks better than I thought. I believed that the channels would appear widened when received above and below the LO frequency with the available IF being less than 1MHz. It also supposed that there would be a "hump" in the central part when adding the powers of both recepcioners (above and below LO).

The dragging will work for all form buttons that activate a keypad

With a short antenna the base station signal is -40dBm.
Guess the shielding is a bit worse when one end of the coax is not connected

Something like this?

Personally, coming from a cyber security situational awareness... I don't comprehend all the wireless infrastructure need and implemented other than to create electromagnetic spectrum situations.?

More reason to invest in wide frequency range portable spectrum analysis systems.? Not only for testing and detecting the typical signals, jamming, noise, static and interference potential.? Really awesome to see such price point and field capabilities.? Even if for some is only less space on the bench.?

Thanks for the review Herb and others.?
