They add harmonic distortion to the signal, making it impossible to do accurate SINAD measurements.

Do you need to accurately control the RF output level?
RiRaRi:
I dont think i need. I need it for testing receivers and also after servicing receiver to check or align the radio. So transmit the sound on needed freq and then moving the screws on receiver to align it properly. Can you do that with tinySA?

That is probably the price without VAT.
RiRaRi is from Croatia. The shop there charges 575,94 € for the SDG 2042X.
Apparently RiRaRi does not want to spend so much.
RiRaRi:
I mean if i need to i will, but i think tinySA is enough for my job. Dont you think?
