Embodiments relate to a concept for testing a transceiver device () which may be coupled to an antenna array (), the antenna array () comprising at least two an antenna elements. It is provided () spatial radiation characteristics of an antenna reference or the antenna array () and at least one antenna element of the antenna array. It is determined (), based on the spatial radiation characteristics and a predefined test quantity for a spatially unaware receiver or transmitter test of the transceiver device (), a spatially aware test quantity for testing the transceiver device () using the spatially unaware receiver or transmitter test based on the determined spatially aware test quantity.

Method, apparatus and computer program for testing a transceiver device

Method of correcting a gain and phase imbalance of an analogue modulator () for multiple channels (CHi) of a multi-carrier transmission signal, the method comprising the steps of determining a gain imbalance correction factor (GCFi) and phase imbalance correction factor (PCFi) for each channel individually and applying said correction factors (GCFi, PCFi) to the corresponding channel (CHi) individually, before the multi-carrier synthesis of the channels is done, whereas step a) for each one of the multiple channels (CHi) is performed in a time-multiplexed manner with step a) for the other ones of the multiple channels (CHi).
