Passive harmonic test system and method

Abstract:

Methods and systems for harmonic intermodulation testing are presently disclosed. The test system includes a signal generator configured to generate a test signal having a first frequency. The test system also includes an antenna system configured to transmit a representation of the test signal and receive a harmonic intermodulation signal. The test system also includes a filter configured to remove signals, from a representation of the harmonic intermodulation signal, over a bandwidth that includes the first frequency. The test system also includes an analysis unit configured to measure a power level of a second frequency contained in the representation of the harmonic intermodulation signal. The analysis unit is also configured to determine a passive intermodulation magnitude at any order based on the power level of second frequency.
