ADC Resolution

I would like to ask what is the ADC resolution (number of bits) of an 8510 system and a PNA system? What are the quantization steps of the calibrated VNA? Do they depend on the source power setting and the maximum input power? Are the ADCs in the 8510 and the PNA linear or logarithmic? 

I somehow feel that quantization errors are not of great importance for VNA measurements but I really like to know how big they are actually .

Best Regards,
