NOTE: All input pulses are supplied by a generator having the following characteristics: tr or tf ≤ 1 ns, pulse repetition rate (PRR) = 0.5 Mpps,
pulsewidth = 500 ±10 ns. CL includes instrumentation and fixture capacitance within 0,06 mm of the DUT. The measurement of VOC(PP)
is made on test equipment with a –3 dB bandwidth of at least 300 MHz.
