The application of frequency-domain method in measuring amplitude-frequency characteristic

The response bandwidth of nuclear electronic units and circuits, such as, the power divider, the shunt, the attenuator, the compensator, the cable, the detector and the laser fiber active network, these electronic units and circuits are applied to measure pulse radiation. Their amplitude frequency characteristic (AFC) is one of important indexes concerned by users. In the paper, we contrast and analyze the merit and defect of different measurement methods, in which frequency-domain method is to have the small link, the small uncertainty and the high efficiency. Thus we nominate frequency-domain method to measure the AFC of these units and we provide instance at the same.
