Abstract
A noise simulator including a reflection absorbing circuit connected between a high-frequency noise pulse generator based on the principle of a charged delay line and a DC capacitor connected to the power line of the equipment under test. The reflection absorbing circuit is composed of a parallel resistor and a series resistor. The resistances of these resistors are determined so that the impedance at the input side of the reflection absorbing circuit in a condition that a predetermined standard impedance connected thereto is equal to the output impedance of the generator and that the impedance at the output side of the reflection absorbing circuit in the condition that the generator is connected thereto is equal to the predetermined standard impedance. A grounded electric conductor plate is movably disposed commonly adjacent to the series resistor and the DC-cut capacitor to adjust the stray capacitance prior to use for noise simulation.
