In practice the sig gen function is ore than adequate for daily needs.
RX alignment, testing rig sensitivity where having a calibrated level output is required.
If I needed a super duper ultra clean sig gen for ISO9000, NPL or NIST standards then
either I'd ask my employer to provide one of win the lottery and pay for one.
For ham radio, hobby use it's more than enough, no complaints here.

AMEN, Martin.? You hit the nail on the head.? Good performance costs, even with used "premium" gear.?

The Tiny / Ultra SA is "what it says on the tin" a 'Spectrum Analyser', the signal generator output, although very useful, is a secondary function, and could be considered to be a free gift :-)
Producing a reasonable quality signal generator with a stable, accurate output, is not an easy task, and if you look on-line at the prices of second hand signal generators that are significantly better than the Tiny / Ultra SA, such as those typically made by HP, Agilent, Aeroflex, Marconi or R&S, you will asked to pay ten to twenty times the price, even for something that is relatively old that is likely to be un-calibrated and unreliable.
Sorry, but I think you need to be more realistic in terms of your expectations.

Hi Andreas, If you are in Germany then try In other countries, the local regulator will generally have something similar on their website, but you may have to dig around quite a bit to find it. The lower frequencies (<30MHz) are easier, as due to propagation signals travel further, and so much more international co-ordination is required. The ITU is generally the best starting point, but individual countries and world regions will have their own national plans based on the ITU regulations. For specific information about your own country, you may have to take a look at some of the on-line hobby / scanning / utility monitoring forums, and do your own detective work regarding specific allocations. I hope this helps. Regards, Martin

Hi Andreas,
Your name sounds a bit like you are located in German. In that case:

There are also a series of books from Michael Martin and Wolf Siebel. Search for "Frequenzliste" or "Sprechfunk Handbuch" at your favorite book store.

QUOTE:?? I would like to have a better quality of?8 point approximation of a sine wave modulation signal.
Goodness sakes !!!!.....? Can't we EVER be thankful for what we have!!????? You can spend over a $1k (used) for something not as good as the TinySA's and the ULTRA.?
A decade ago, a good SA would go for over $5k to start.? A reasonable VNA for well over $10k to $15k - absolute rock bottom.? Neither of these price points are reachable by the average amateur or the schools for any quantity buys for students.? Today we have those wonderful and capable pieces of gear for extremely reasonable prices.? I'm extremely thankful for these "gifts" from those who know how.? I can handle analog, but not today's digital schemes which are required for these instruments.? Thank you, guys and gals ! ! ! ! ?
Sure, I want the technology of electrogravatic movement about the universe (heaven forbid, I mean the OORT cloud and beyond, not just LEO or geosync!!).? I want the ability to visit the regions of the Betty/Barney Hill holographic map shown them onboard an alien craft.? I want to visit the Sirius system.? I want to visit the source of the Dogon knowledge of deep space (well.... WELL beyond our little universe).? Of course all this within an earth month's time.
Be thankful for what we have!!!!!

Re: Setting time is difficult
Is it possible that time on screen does not change immediately.? I turned the SA off and then on, and time seems to be? correct now.

Re: Setting time is difficult
I? tried this
It almost works, date and clock button is green, but nothing happens. The time is as? it was.
Then? the .py code. How can I make it run? This is a Windows 10 PC.

Re: Setting time is difficult
Try it, some basic tasks can definitely be done with it on TinySA too; such as time synchronization, FW update...

sugeda,
Try using a low-pass filter.? That is how some of the kit builders provide a sinewave output.? There are switchable ones like these:
Building a holder for plug switchable filters is the least costly, depending on the frequency range.? Since the TinySA output is a squarewave, the filter would be just under the 3rd harmonic of the primary frequency.

Also this tool has NanoVNA in its name, but it should also work for tinySA Ultra: I cannot check because my tinySA (Basic) has no real time clock support.
