Hi Alfredo,
You may confirm the same with the company before you order it. In my long career as an Electronics Engineer I haven't come across any test equipment that does not require periodic re-calibration. Most of them are good for one year but some for 3 years. Once again the re-calibration is required only if you want precision accuracy traceable against primary standards. That is usually the case with high precision manufacturing like space, defense , cellphone etc. I think for HAM use one need not spend money for annual re-calibration.

I have decided to buy a Spectrum
Analyzer  https://www.rigolna.com/products/spectrum-analyzers/dsa700/

It has 500 mhz of bandwidth
and 5% of accuracy for dBm measurements. (+/-0.25dB)

I hope it doesn't require
anual calibrations.
