includes probe and jig capacitance.
Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 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 ≤ 10 MHz, Z
O
= 50Ω, t
R
≤ 2.0ns, t
