C_L = Load capacitance: includes jig and probe capacitance.
R_T = Termination resistance: should be equal to Z_OUT of the Pulse Generator
Output 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, Z_O = 50Ω, t_R ≤ 2.5ns, t_F ≤ 2.5ns.
The outputs are measured one at a time with one transition per measurement.
