Paper Abstract

A data compensation routine using deconvolution technique for an ultra-wide-band (UWB) exposure facility is described. The single shot measuremetn system mainly includes a Tektronix SCD 5000 sampling scope and an EG&G D-dot sensor. The transfer function of the measuremetn system was evaluated with a reference impulse generated by a picosecond pulse labs 4050B picosecond pulse generator. An iterative Hilbert transform was applied to ensure the causality of the results of deconvolution. With software compensation, the bandwidth of the measurement system has been expanded from less than 2 GHz to about 15 GHz. The analysis shows that this exposure system can deliver UWB pulses with a rise time less than 150 ps, a magnitude from 50 to 120 kV/m depending on the location along the center line, and a pulse width about 5 ns.
