So in your VNA: What it does is measure the response of your network over a bit of the spectrum at a time. It sends out RF signals at some frequency and analyzes the reflections. A tuneable oscillator is fed into a mixer with the incoming reflections. This down-converts the reflections from their RF frequency to a fixed IF.
The VNA Output (TX) is connected to the output PDN through a direct connection. The VNA Input (RX) is connected to the output of the PDN through a semi-floating differential amplifier on the VNA RX side. Residual impedance will directly affect very low impedance measurements.
