Abstract
A sampling system (1) comprises a sampling circuit (2) for supplying a signal to be sampled and a pulse generation circuit (3) for generating two sampling pulses, which are opposite in phase, for the sampling circuit (2). In order to achieve as good a balance as possible and in order to minimize the influence of parasitic effects which affect the balance, charge storage components are formed as the distributed capacitance of a symmetrically coupled microstrip transmission line (pt11). Triggering and DC biasing of a step recovery diode (D3) in the pulse generation circuit is carried out outside of the characteristic environment of the step recovery diode (D3) at a potential node (e3) of a reflection transmission line (rt11, rt12).
