Power and Phase Relationship Measurement - PNA/ENA

Hi all,

it's puzzle to me that network analyzer can measure in phase delay. Do we have any specific chapter or user guide talking about this measurement?

if network analyzer is pumping out in power (dbm) and measure gain/loss in dB, so how would it help to measure phase delay?

unless the oscillator inside is pumping out the voltage and we are measuring in relative phase delay. So all NA is using voltage but converting in dBm for the measurement and display as result?

thanks you.
