平方公里阵列（SKA）射电干涉仪的中频阵列由成形偏置格里高利反射器天线组成[1]。每个反射器系统都有一组准倍频程和宽带接收器，用于校准每个反射器天线的单个波束接收波束[2]。由于这些接收器具有非标准接口，并且由于商业设备通常无法测量接收器的极高性能要求，因此需要开发专门的测试设备来表征和验证这些接收器的性能。
The mid-frequency array of the Square Kilometre Array (SKA) radio interferometer consists of shaped offset Gregorian reflector antennas [1]. Each reflector system has a set of quasi-octave and wideband receivers that collimate a single boresight receive beam per reflector antenna [2]. As these receivers have non-standard interfaces and because commercial equipment is typically not capable of measuring the extremely highperformance requirements of the receiver, specialized test equipment needs to be developed to characterize and verify the performance of these receivers.
