阅读:977发布:2021-11-25

专利汇可以提供Satellite line simulator专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain a satellite line simulator to perform the evaluation test of a communication protocol between one station and plural stations by providing a logic circuit for the output of plural pairs of variable delay circuits to delay data signals for designated time, respectively, and a branch circuit to output the data signal to the variable delay circuit after branching.
CONSTITUTION: The data signals at a slave station side are delayed for time designated by digital switches 31-38 at programmable delay circuits 21-28 via interface circuits 11-18, and furthermore, the logical sum of the signals is outputted to a master station side via an interface circuit 60. Meanwhile, an input signal from the master station side is branched at the branch circuit 50 via the interface circuit, and branched signals are inputted to and delayed at the programmable delay circuits 21-28, and are outputted to each slave station via the interface circuits 11-18. Thus, the line simulator to perform the evaluation test for the communication protocol, etc., between one station and plural stations can be performed with an easy operation.
