Measurement of Impulse Spectrum Amplitude for Use in EMI Susceptibility Tests



Nicholas Paulter, Donald R. Larson


A system for measuring the impulse spectrum amplitude of the output of impulse generators and the response of receivers is described. The calibration procedures used in this measurement system were recently modified, which resulted in a reduction in the time for measurement and in the magnitude of the published uncertainties. The uncertainties for the bandwidth of 10 MHz to 4 GHz have been reduced from ? 0.5 dB to less than ? 0.1 dB for the parameter of impulse spectrum amplitude.
