All input pulses are supplied by a frequency generator with the following characteristics: TR and tF
RL = 50 ohm/100 ohm
CL includes instrumentation and fixture capacitance within 6 mm of the DUT.
TPA and B are used for prop delay and Rise/Fall Measurements. TPC is used for VOC measurements only.
All outputs should be loaded, used or not, in order to minimize noise and currents.
