Description and Variable Parameters
Oscillation
surge
Surge waveform with damped oscillation
Oscillation frequency (0.01 to 50.00 times basic frequency)
Damping time constant (0.01% to 100.00% of basic period)
Trailing time constant (0.01% to 100.00% of basic period)
Pulse surge
Pulsed surge waveform
Rising time (0.01% to 100.00% of basic period)
Duration time (0.01% to 100.00% of basic period)
Remark: The rising time represents the time from the 10% threshold to
the 90% threshold of the rising edge. The duration time
represents the time from the 10% threshold of the rising edge to
the 10% threshold of the next falling edge.
