Subject: Calculate Path Loss

Hi!

I conducted some indoor propagation measurements using
vector network anlyzer (VNA). The measurement setup
are as follow:

Transmitter (TX) side:
Port1 of VNA(set at -10dBm)+1m cable(loss
-1.2dBm)+power amplifier(gain +30dB)+2m cable(loss
-2.5dBm)+TX antenna(gain 2dBi)

Receiver (RX) side:
RX antenna(gain 2dBi)+20m cable(loss -31.6dBm))+low
noise amplifier(gain +32dB)+1m cable(loss
-1.2dBm)+Attenuator(set at 20-50dB depending on TX-RX
distance)+1m cable(loss -1.2dBm)+Port2 of VNA

How do I remove all the effect of measurement system
from the recorded channel frequency response so that I
can find the path loss at each TX-RX separation
distance?

Thanks.

Linda
