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