2. Waveform–A is for an output with internal conditions such that the output is low except
when disabled by the output control.
3. Waveform–B is for an output with internal conditions such that the output is high except
when disabled by the output control.
4. All input pulses are supplied by generators having the following characteristics:
PRR ≤ 10MHz, Zo = 50 Ω.
5. The output are measured one at a time with one transition per measurement.
