Parameter Measurement Information

GUID-CA0C96B8-3776-4270-A2B8-8D28C584173F-low.gif
CL includes probe and jig capacitance.
All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, tr/tf = 30 ns.
The outputs are measured one at a time, with one transition per measurement.
