Recent advances in instrumentation, motivated by the volume and cost d
emands of the commercial wireless marketplace, allow a powerful RF/mic
rowave test bench to be assembled at relatively low cost. A versatile
test bench comprising a vector network analyzer (VNA), spectrum analyz
er (SA) and signal source is described, along with test techniques for
a wide range of RF/microwave measurements in the 0.3 to 3 GHz frequen
cy range.
