PARAMETER MEASUREMENT INFORMATION (continued)
NOTE: 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 . C
L
includes instrumentation and fixture capacitance within 0,06 mm of
the D.U.T.
Figure 5. Enable and Disable Time Circuit and Definitions
NOTE: All input pulses are supplied by an Agilent 81250 Stimulus System. The measurement is made on a TEK TDS6604
running TDSJIT3 application software.
