Notes: A. All input pulses are supplied by a generator having the following characteristics: tr or tf ≤ 1ns, pulse repetition rate (PRR) - 50 Mpps,
pulse width = 10 ±0.2ns.
B. RL = 100Ω or 50Ω ±1%.
C. CL includes instrumentation and fixture capacitance within 6mm of the D.U.T.
D. The measurement of VOC(PP) is made on test equipment with a –3dB bandwidth of at least 300 MHz.
