Hi
As a hamradio operator what can i do better with TinySA ultra then NanoVNA H4 ? What kind of measurement with TinySA can be really usefull for antenna, filtering .. around hamradio activity , did sdrplay spectrum display can replace TinySA on moste cases ? i see that it has a handy signal generator but what really much important to do with?

They are completely different instruments, used for completely different
purposes.The NanoVNA is a vector network analyzer. It can be used to
measure resistors, capacitors, inductors, transmission lines, antennas,
etc. It can measure SWR. The TinySA is a spectrum monitor. It can do none
of the things I listed above. But it can show the spectrum in any given
frequency segment. The TinySA Ultra goes up to over 12 GHz. I often use it
to peak pipe cap bandpass filters up through 10 GHz. A power meter often
shows power out, but the filter could be tuned to the wrong frequency. The
TinySA verifies I am tuning the filters to the correct harmonic.

The calibrated signal generator output on the TinySA Ultra is a great tool to calibrate or check your S meter and also very useful for determining and/or checking your receivers sensitivity. It also provides modulated AM and FM modulated outputs(AM amplitude as well as modulation frequency adjustable, FM deviation adjustable). The TinySA Ultra is a great tool for checking a transmitters harmonic content assuming you have appropriate attenuators. The TinySA Ultra is useful for viewing and sniffing out sources of RFI. The tinySA Ultra can view a much much larger spectrum than a SDR receiver. The TinySA Ultra can measure a transmitters output level assuming you use appropriate attenuators, the TinySA Ultra can be used to make accurate field strength measurements if you know the antenna factor. I’m sure there are many other useful options/features but the ones I listed are common features that I use all the time. The TinySA can do most of what the TinySA Ultra can do but it’s more limited.

Yes. The TINYSA is highly useful for frequency domain measurements.

As well, the NANOVNA is equally useful for impedance domain measurements.

As well, an o'scope is equally useful for time and amplitude domain
measurements.

Any ham should have all of the above!

In these modern times, none of the above will break the check book or
credit card.
