Probing Principles
Maximum Allowable Pulse Width
To determine the maximum allowable pulse
width do the following:
1.
Measure the peak current of the pulse.
2.
Divide the Ampere-second (or
Ampere-microsecond) speci
fi
cation
for the probe by the measured peak current
of the pulse:
The quotient is the maximum allowable
pulse width (PW
max
).
3.
Check that the pulse width at the 50% point
of the measured signal is less than the
calculated maximum allowable pulse width
(PW
max
).
