Testing Antennas with a Network Analyzer Jan 6, 2013 9:00 AM, By Jeremy Ruck, PE No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer.

The network analyzer measures two properties of the circuit to which it is connected: return loss (S11) and insertion gain or loss (S21).

If you work with RF circuits and antennas, you know how challenging it can be to troubleshoot them. RF signals are affected by many factors, such as noise, interference, impedance, reflection, and ...

When measuring a circuit or device with a network analyzer, engineers generally inject a signal and believe that the measured results reflect that of a “small-signal” AC measurement.
