Abstract

In some implementations, a network test device may apply a first calibration scheme to a transceiver array of the network test device using a first calibration signal, wherein the first calibration scheme is to measure a relative frequency response between transceivers of the transceiver array and remove errors associated with the relative frequency response, where the relative frequency response is associated with an amplitude and a phase. The network test device may apply a second calibration scheme to the transceiver array using a second calibration signal, wherein the second calibration scheme is to remove changes in the relative frequency response, where the changes in the relative frequency response are associated with changes in the amplitude and in the phase. The network test device may evaluate a wireless base station using the transceiver array that is calibrated based on the first calibration scheme and the second calibration scheme.
