Hi, Would like to know meas. unc associated with measuring absolute power using a PNA.

Have an amp, input 2 dBm, output approx 27 dBm. I do a source cal, kick in 35 dB of  receiver atten and perform a B receiver power cal. How accurate is the receiver power measurement ? Can I get the unc numbers from the VNA uncertainty calcuator ?
