Test interface board, test system, and test method and device

A test interface board, a test system, and a test method and device are provided. The test interface board includes an encoder, a signal copier, and a decoder. The encoder digitally encodes test data to generate a modulation signal. The signal copier copies the modulation signal by inductively coupling the modulation signal and outputs at least one copy signal corresponding to the modulation signal. The decoder decodes the modulation signal and the at least one copy signal in order to test at least two semiconductor devices. 提供了测试接口板、测试系统、测试方法以及装置。测试接口板包括编码器、信号复制器和解码器。编码器数字地编码测试数据以产生调制信号。信号复制器通过感应地耦合调制信号来复制调制信号并输出与调制信号对应的至少个复制信号。解码器将调制信号和至少个复制信号进行解码，以测试至少两个半导体器件。
