Abstract
A test system is provided operating in the 76-77 GHz range for testing components of a collision avoidance radar system. The system uses a Scorpion vector network analyzer (VNA) having an internal stimulus source synthesizer operating over a narrow 3-6 GHz range. The source signal from the Scorpion VNA is up-converted in a test module to a 75-78 GHz signal, without using a non-linear multiplier between the Scorpion VNA source and a device under test (DUT). A 72 GHz. local oscillator (LO) signal is provided for up-conversion as well as down-conversion using a dielectric resonator oscillator (DRO) phase-locked to a crystal oscillator of the Scorpion VNA. The DRO is included internal,to the test module. Fundamental up-conversion and down-conversion is provided in the test system so that significant conversion losses do not occur, as when higher order harmonics are used.
