Abstract

We have demonstrated a new technique to characterize wideband nonlinear waveforms at microwave carrier frequencies. The analog sampling bandwidth can be increased with wider bandwidth sampling modulators and shorter optical pulses. The instantaneous Nyquist bandwidth can be extended using time-interleaving techniques.
