I have been reading about various methods to perform a Cable Path Loss for RF Testing but not being a core RF person, I needed some insights on how it is done in Field or Lab. Here is my understanding so far:
Method1: Signal Generator + Power Meter Generate about 0 dBm of power from the Signal Generator and measure the same on the Power Meter e.g. assuming 10 dB pads + cable loss 5 dB = -15 dBm (this the total cable path loss).
Method2: Network Analyzer Connect the 2 ends of the paths to Port 1 & Port 2 of the Network Analyzer and measure the S21 parameter.
I kind of get the idea of Method 1 but do not understand the Method 2 much.
