We present a photonically enabled rf arbitrary waveform generator that can rapidly switch between two output waveforms. This method is based on line-by-line shaping of an optical comb and then converting the optical pulses to rf waveforms with a fast photodetector. It uses a single diode laser as the optical source and selects different patterns preprogrammed into an optical pulse shaper by shifting the laser frequency. We demonstrate minimum update delay times of 0:45 ns.
