Multi-output Acousto-optic drivers

These drivers based on Direct Digital Synthesizers (DDS), produce multiple fixed stable and accurate RF frequency signals for AO modulators, frequency shifters and acousto optic deflectors. Their brand new design with “on the edge” technology offers unique performance in term of accuracy, speed and stability (single/multi-line), thanks to their internal temperature correction and high linearity design. There is a range of compact and user friendly 2, 4 and 8 output drivers which have been honed for the specific needs of the applications. All of these RF drivers are compatible with AA’s own and other manufacturers’ AO modulators, frequency shifters and acousto optic deflectors, and they are considered to be of high quality and impressive performance by current users. The multi output drivers are based on DDS (Direct Digital Synthesizers) which offer high frequency, accuracy and stability. Each DDS operates with a common clock reference so that they provide phase locked output signals when driven at the same frequency. The frequency and power are driven via USB/RS232 communications ports and external control signals allow use for fast AM control of the channels/outputs. Embedded power amplifiers offer up to 4 watts per output and the manufacturer AA will provide external power amplifiers for higher powers.
