Probing Principles
Maximum Allowable Pulse Width
To determine the m axim um allowable pulse
width do the following:
1. Measure the peak current of the pulse.
2. Divide the Ampere-second (or
Ampere-microsecond) specifi cation
for the range setting of the TCP0150 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
).
