6.2 Meaning of Each Parameter and Waveform Examples
WF1967/WF1968 6-25
b) Pulse Surge

Overview
Simulates a surge waveform. Does not have an oscillation component.
Application examples
• Simulates the transient voltage waveform of a car battery

Meaning of each parameter
The example shows the case where the amplitude
range is 0/+FS.
• Rising time (Tr)
Time for the amplitude to rise from 10% to 90%
of the peak value.
Variable range: 0.01% to 100.00% of basic cycle
• Time duration (Td)
Pulse width with an amplitude 10% or greater of
the peak value.
Variable range: 0.01% to 100.00% of basic cycle
Peak value is fixed at
＋
FS.
The tail does not go to zero. Please note that the greater the time duration the more the tail will float
above the zero level.

Waveform examples
The polarity and amplitude range are all Normal, 0/+FS.

Remarks
The prescribed waveform will not be created unless the condition that approx. 1.839
＜
Td / Tr is
satisfied.
