In the domain of electromagnetic compatibility (EMC), highly specialized and complex receivers are widely used for radio disturbance and immunity applications. In order to calibrate such receivers, specially designed test generators are often used. A short and repetitive pulse is applied to test different receiver parameters in a very efficient way. The traceable calibration of impulse generators is thus an important issue in radio frequency (rf) metrology.

Two different methods are compared: A traditional frequency domain method and an efficient time domain method, both giving good agreement. The different approaches with all necessary steps are shown, uncertainties, advantages and drawbacks are discussed.

Both methods are applicable with good results. The time domain method seems to be the better choice because it results in a much faster procedure and in lower uncertainties, but it requires a high precision oscilloscope.
