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