Impulse signal and step signal
The E5070A/E5071A lets you simulate the response from the DUT to 2 types of signals:
impulse signal and step signal. The impulse signal is a pulse-shape signal in which the
voltage rises from 0 to a certain value and returns to 0 again. The pulse width depends on
the frequency sweep range. The step signal is a signal in which the voltage rises from 0 to a
certain value. The rise time depends on the maximum frequency within the frequency
sweep range.
NOTE For more information on how the frequency span setting affects the pulse width and the
rise time, refer to "Calculating necessary measurement conditions" on page 182.
