Abstract : The patent relates to a laser beam passed through a Bragg cell driven by a plurality of voltage controlled oscillators having different center frequencies. The voltage controlled oscillators are modulated by analog voltage waveforms representative of various discrete signals. The Bragg cell divides the laser beam into separate beams, one for each voltage controlled oscillator, with each beam deflected in accord with the signal. Moving photosensitive recording paper makes a simultaneous record of the independently modulated beams providing a multi-trace oscillograph recording of the signals.
