Figure 5. Driver VDO Test Circuit
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 µ s. C
L
includes instrumentation and fixture capacitance within 0,06 mm of
the D.U.T. The measurement of V
OC(PP)
is made on test equipment with a –3-dB bandwidth of at least 1 GHz.
