A. R_T termination resistance should be equal to Z_OUT of pulse generators.
B. C_L includes probe and jig capacitance.
C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Z_O = 50 Ω, slew rate
≥ 1 V/ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. t_PLH and t_PHL are the same as t_pd.
