[en] This paper describes a new kind of pulse generator, able to provide not only two pairs of coincident pulses, with continuously variable amplitude (0-5 V) for each pulse and delay (40-150 μs) between the two pairs - energy simulation - but also the corresponding timing signals - time of flight simulation - with different intrinsic variable delays ranging from 50 ps up to 128 ns, in steps of 50 ps, with a proper time resolution better than 15 ps. Some experimental results, obtained using the present device, are also reported. (orig.)
