From Output
Under Test
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
The outputs are measured one at a time with one transition per measurement.
L
includes probe and jig capacitance.
