Parameter
All input pulses are supplied by a frequency generator with the following characteristics: t
RL= 50 ohm ± 1% Zline = 50 ohm 6”.
CL includes instrumentation and fixture capacitance within 6 mm of the UT.
TPA and B are used for prop delay and Rise/Fall measurements. TPC is used for VOC measurements only and is otherwise connected to V
