The Model STIC "Step to Impulse Converter" is a special circuit that converts step-like waveforms to impulses for use in TDR measurements and other applications. If the input to STIC is an impulse, a single cycle of a sinewave-like waveform is output.
The performance of Model STIC Step to Impulse Converter is highly dependent on the connector options chosen and the characteristics of the step-like input signal.
