Based on the limited info you provide, perhaps some on this forum automatically know the level of rf you need to measure as well as the desired frequency accuracy. Not me.
Any spectrum analyzer can measure any level, with appropriate internal/external attenuation and/or pre-amplification. They don't specify frequency accuracy, but the minimum available BW is 50 kHz, which forms a lower bound on that number. Also the 5 ppm stat on the local oscillator is 12 kHz at 2.4 GHz, and 36 kHz at the third harmonic. Those will likely rss with 50 kHz uncertainty. Again, don't know what your frequency accuracy need is, but most specs use 1 MHz BW at these frequencies for EMI work.
