Probing Principles
Maximum Allowable Pulse Amplitude
To determine the maximum allowable pulse
amplitude do the following:
1.
Measure the pulse width at the 50% points.
2.
Divide the Ampere-second (or
Ampere-microsecond) speci
fi
cation
for the TCP202A probe by the pulse width.
The quotient is the maximum allowable
pulse amplitude; the peak amplitude of the
measured pulse must be less than this
value.
For example, the TCP202A probe has a
maximum Ampere-second product of 500 A-
μ
s.
If a pulse measured with the probe has a width
of 11
μ
s, the maximum allowable peak current
would be 500 A-
μ
s divided by 11
μ
s, or 45.5 A.
