I am trying to re-calibrate my RF power meter, since the power meter resolution is 0.01dBm what kind of signal generator should I use ? most of the signal generator has output accuracy +-1dB or +-0.5dB only. and step attenuators also is in the +-1dB to +-0.5 dB accuracy range. did factory really calibrate the power meter with signal source of +-0.01dB accuracy before they ship the product out?
