Any talk of a 4" ?
Or high powered readers ;)

Hi,

Here some info on my latest project: https://vma-satellite.blogspot.com/2021/04/vma-simple-spectrum-analyser-for-tinysa.html

I am making a special version of my "VMA Simple Spectrum Analyser" software for the TinySA!

Regards,
Vitor

--- Quote ---Question
Will there be a 4" or larger version of the tinySA?
Answer
To reach the largest set of customers it was deliberately decided to launch the 2.8" version of the tinySA first. Next steps will depend on continued sales . A 4" version is expected to fit within the cost and affordable sales price but any communication about a 4" tinySA will only happen when there is certainty about an introduction date. Larger display's are not expected as these will have a substantial cost impact.

I'd argue the notion that the smallest price reaches the largest set of customers. It is not true if in the attempt to reduce the price, questionable compromises are made. I believe a 2.8" screen is one of those. 2.8" is just too small for a device with such a complex user interface as a spectrum analyser. It's OK for an MP3 player where all you gotta do is browse through a list of songs, and after selection display cover art. In a spectrum analyser not only the UI is an order of magnitude more complex, but also in the displayed chart you want to hunt for details that are lost on such a small screen, with such a low resolution. With a 2.8" screen IMHO the device is just a laptop dongle, and therefore not a pocket size device anymore.

Not questioning Hugen's electronic design capability, getting that functionality (and quality) into such a small device is not a small feat. But 2.8" or 4" is a marketing decision, and I fear it wasn't wise. Particularly as, with the extra PCB space that a larger screen affords, probably several of the  limitations can be mitigated, or even eliminated.

JeremyC:
I have question about the TinySA when it’s used as signal generator. How accurate is the output power/voltage?
For instance, when the output power is set to -15dBm at 10MHz frequency, what measured power/voltage will be when the frequency will be changed to 50MHz, 100MHz, 200MHz, 300MHz and 350MHz?

Thanks.
