A. The input pulse is supplied by a
generator having the following characteristics: PRR ≤ 50 kHz, 50% duty cycle, tr
≤ 3 ns, tf ≤ 3 ns, ZO = 50 Ω. At the input, a 50-Ω resistor is required to
terminate the Input Generator signal. The 50-Ω is not needed in actual
application.
B. CL = 15 pF and includes
instrumentation and fixture capacitance within ±20%.
