Ultra wideband signal sources for interference measurements

Two prototype ultra wideband (UWB) signal sources using the burst CW concept to generate the UWB pulses have been developed and tested. The sources can be used for testing the possibility of interference to communications equipment by UWB signals. The first source has variable pulse width and pulse repetition frequency as well as a variable centre frequency. The second source has a dithering circuit, which 'whitens' the spectral output.
