TEST EQUIPMENT AND TESTING METHODS BASED ON HARMONIC BEAMFORMING
First Claim
1. A method of harmonic testing of cellular communication assemblies for emissions compliance, the method comprising:
- transmitting a signal beam using an antenna array of a respective cellular communication assembly after manufacture thereof, the signal beam including a fundamental lobe and one or more harmonic lobes;
determining one or more testing locations of the signal beam based on detecting a direction of the fundamental lobe using test equipment, the one or more testing locations corresponding to locations associated with the one or more harmonic lobes;
evaluating a level of harmonic emissions at each of the one or more testing locations using the test equipment; and
establishing that the respective cellular communication assembly complies with emissions testing when the level of harmonic emissions at each tested location is determined to be below a predetermined threshold.

Abstract
Apparatus and methods for radio frequency emissions testing based on harmonic beamforming are provided herein. In certain configurations, a method of emissions testing of cellular communication assemblies for emissions compliance is provided. The method includes transmitting a signal beam using an antenna array of a respective cellular communication assembly after manufacture thereof, the signal beam including a fundamental lobe and one or more harmonic lobes. The method further includes determining one or more testing locations of the signal beam based on detecting a direction of the fundamental lobe using test equipment, the testing locations corresponding to locations associated with the harmonic lobes. The method further includes evaluating a level of harmonic emissions at each of the one or more testing locations using the test equipment to establish whether or not the respective cellular communication assembly complies with emissions testing.
