The Maxi QSD-RF Driver is a 200 Watt Q-Switch Driver, which is in its function especially tailored to the conditions of acousto-optic control. The configurable first-pulse automatic allows a quick and ease adaptation to various first pulse suppression required on engraving to achieve constant and stable results. The 200 Watt Q-Switch Driver provides its output power continuously over the entire frequency range. Precisely controlled and constant properties from module to module, in performance and frequency stability promotes the application of 200 Watt Q-Switch Driver, whereby the short switching times allow a high modulation frequency. The high-frequency output signal (RF amplitude) can be modulated and varied with an external analogue voltage 0-100%.A graphical user interface ensures a ease setting of all parameters. The output power and the first pulse suppression adjustments are programmable via the integrated serial interface, as an option there is a graphical user interface available. In addition, the high-frequency output signal (RF amplitude) can be modulated and changed with an external analogue voltage of 0-100%.
