Theory of Operation
The 8510XF applies RF test signals to the DUT, and compares these incident
signals to whatever is reflected from (or transmitted through) the DUT. The
incident, reflected, and transmitted signals are separated out by means of
directional couplers, and mixed down to create a set of four IF inputs to the
analyzer, as illustrated below.
