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.
