NOTES: A. CL includes probe and jig capacitance.

B. In the examples above, the phase relationships between inputs and outputs have been chosen arbitrarily.

C. All input pulses are supplied by generators having the following characteristics: PRR

≤ 1 MHz, ZO = 50 Ω, tr ≤ 7 ns, tf ≤ 7 ns.

D. The outputs are measured one at a time, with one input transition per measurement.
