DAQ(Data Acquisition Equipment) of an EMS(Electro Magnetic Susceptibility) data monitoring system is provided to reduce the cost by adopting a multi-channel activation method instead of an independent channel type satellite in testing the existing EUT(Equipment Under Test). DAQ(140) of an EMS data monitoring system for executing an electromagnetic susceptibility test of EUT(150) in an anechoic chamber is composed of a power supply(220) receiving AC(Alternating Current) power and converting the AC power into DC(Direct Current) power for driving the DAQ; an optical converter(230) converting an input optical signal into an electric signal or an output electric signal into an optical signal; a DAQ processor(240) controlling the signals input/output from the optical converter; and analog input and output terminals(AI_ch1 to AI_ch8,AO_ch1,AO_ch2) electrically connected with the DAQ processor to form plural independent channels outputting a control signal of the EUT or receiving an output signal of the EUT. The analog input and output terminals are formed as many as the number of the independent channels. |
