The GLN – 5040A Two Line V – Network is used for EMI testing. It provides stable impedance for the EUT terminals and the reference ground within the conducted emissions range. The GLN – 5040A also isolates the unwanted network signals from the power supply unit and only couples the disturbance voltage of the measured device to the receiver. The product’s performance is in compliance with the standard requirements of CISPR16 – 1 – 2 for V – networks with a simulated impedance of 50? H + 5 ?) || 50 ? in the frequency range of 9kHz to 30MHz. It uses standard BNC output connector with 50 ? output impedance to match any measurement devices such as receivers and spectrum analyzers.
