NOTE: All input pulses are supplied by a generator having the following characteristics: tr or tf ≤ 0.25 ns, pulse repetition rate

(PRR) = 50 Mpps, pulse width = 10

± 0.2 ns. CL includes instrumentation and fixture capacitance within 0,06 mm of the D.U.T.

Measurement equipment provides a bandwidth of 5 GHz minimum.
