    New item on the market.
    TinySA is a portable Spectrum Analyzer/Frequency Generator that might fill the niche for those who need an analyzer for your bench that covers two tools - for either testing a radio's 2nd harmonic level - or the generator/analyzer function to build RF filters.
    Perhaps other needs as well . . .

    Got my Nano VNA a couple weeks ago. Still need to learn about using it. 20201103_131141.jpg

    I'm considering getting the TinySA to use on my bench for testing 2nd harmonics on CB radios and checking for splatter.

    The sig/gen part provides a sine wave up to 350Mhz and from 350Mhz to 960Mhz, it gives a square wave function. It provides some modes, such as AM, FM, and wide FM. Also has a sweep gen function as well.

    Don't know anything about thee NanoVNA; what is it capable of?

    The NanoVNA is a palm-sized 2-port vector network analyzer with a huge range of abilities including computer interface. It offers smith chart, SWR, delay readout, and a host of other functions, I've used mine for antenna analysis, tuning antenna traps, checking coax cable integrity visa S12 measurements, and checking cable length using time domain reflectometry via the interface software. I have by no means explored all of the possible functions yet, but I don't see why it couldn't be used as a step-swept signal generator or tracking generator as well. All in all, it is an amazing little gadget for the price, and the price is inline with the TinySA (which I am now eyeballing quite hard, thanks to the OP, lol!!!)
