Abstract
A test system for testing an array antenna under test with at least two antenna elements comprises a signal generator that generates a test signal, a signal splitter that splits the test signal into a plurality of antenna source signals for the single antenna elements, and a vector multiplier for each one of the antenna source signals, wherein the vector multipliers each adjust the amplitude and/or phase of the respective antenna source signal according to predetermined adjustment parameters and wherein output ports of the vector multipliers are connected to respective ones of the antenna elements.
