Well if you want to measure spurious outputs from a transmitter the Tiny Sa can do that easily, but you must use an attenuation to keep the levels within the allowable limits.
Some take the harmonics measurement with an appropriate attenuation, then add an additional attenuation and take the readings. In some cases the input of the Sa can be overloaded and it produces harmonics. By running the test that way you can be sure the trash is coming from the transmitter. You can use the Sa to verify compliance with FCC.
Quite a few of the lower cost it's don't meet the spec. The Tiny Sa Ultra has a harmonics mode.

Never stellar, my aging mind deteriorates faster than I am aware of.

I do understand why I should use an attenuator to protect various pieces of equipment from "excessive" rf.

Maybe I misunderstand why anyone might want to connect the output port of an active transmitter to any port of a TinySA.

Regarding the hf rf environment of my home, I have found a tv high pass filter to be of value for my sdr setup and TinySA use; in particular:

Too much to learn and not enough mind or time.
