7 Parameter Measurement Information

A.

The input pulse is supplied by a generator having the following characteristics: PRR

≤ 50 kHz, 50% duty cycle, tr ≤ 3

ns, tf ≤ 3ns, ZO = 50 Ω. At the input, 50 Ω resistor is required to terminate Input Generator signal. It is not needed in

actual application.

B.

CL = 15 pF and includes instrumentation and fixture capacitance within ±20%.
