All input pulses are supplied by a generator having the following characteristics: t
r
or t
f
≤
1 ns, frequency = 1 MHz,
duty cycle = 50
±
5%.
R
L
is 1% tolerance, metal film, surface mount, and located within 2 cm of the D.U.T
C
L
is the instrumentation and fixture capacitance within 2 cm of the D.U.T. and
±20%.
The measurement is made on
test equipment with a –3dB bandwidth of at least 1GHz.
