Notes:
3. All input pulses are supplied by a frequency generator with the following characteristics: tR and tF ≤ 1 ns; pulse rerate = 50 Mpps; pulse width = 10 ± 0.2 ns.
4. RL= 50 ohm ± 1% Zline = 50 ohm 6”.
5. CL includes instrumentation and fixture capacitance within 6 mm of the UT.
6. TPA and B are used for prop delay and Rise/Fall measurements. TPC is used for VOC measurements only and is otherwise connected to VDD- 2.
