Output Waveform 1 is for an output with internal conditions such that the
output is LOW except when disabled by the control output.
Output Waveform 2 is for an output with internal conditions such that the
output is HIGH except when disabled by the control output.

All input pulses have the following characteristics: Frequency = 10MHz, tRISE = tFALL = 2 ns (10% to 90%), ZO = 50Ω.
The outputs are measured one at a time with one transition per measurement.
