3.4 Return Loss
GSA.8821 is placed on a piece of Styrofoam on an empty carton for measuring free space
return loss. Since GSA.8821 is designed to mount in a car, it also adheres directly on the test
instrument metal box to simulate the application environment. Agilent 8753SE Network
Analyzer is used for the S11 measurement.
