AODF DUAL DRIVER
Dual 15 W Output
Gooch&Housego’s dual 15 W output RF Driver provides two independent RF channels with a fast parallel interface as well as USB controllability.
Ideally suited for controlling a two element phased array acousto-optic (AO) deflector, the driver can also be used to drive two single element AO deflectors for two dimensional scanning. The Dual Driver has 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 AO deflectors.
Two independent 15 W RF drivers are housed in a compact form factor with a fast parallel frequency programming interface. Remote control over a USB interface through an intuitive command set is also available. Dual amplitude and relative phase control inputs are included on the rear panel with the parallel interface connectors. The default, power - on is Stand-alone mode, not requiring PC control; connecting the USB connection enables a Host PC mode. The waveform playback mode is also available for user-defined application specific waveforms, e.g. custom frequency chirp or FM modulations.
The Dual Driver is available in two frequency bands, and each unit includes a monitor output that covers the entire 20-450 MHz frequency band. Driver functionality can be re-configured over the USB interface; for further details please contact us.
