Product description

This RF driver is designed to drive two-element phased array acoustic-optic beam deflectors for two-dimensional scanning as well as additional flexibility for controlling AO tunable filters. With its arbitrary waveform playback capability, multiple wavelengths can be simultaneously diffracted by tunable filters and multiple beam spots can be generated by beam deflectors.

Key features

  • Fault protection on low power, high power, and high VSWR.
