A. All input pulses are supplied by a generator having the following characteristics: t
r
or t
f
≤ 1 ns, pulse-repetition rate
(PRR) = 0.5 Mpps, pulse width = 500 ± 10 ns; R
L
= 100 Ω ; C
L
includes instrumentation and fixture capacitance within
0,06 mm of the DUT; the measurement of V
OC(PP)
is made on test equipment with a -3 dB bandwidth of at least 300
MHz.
