The Femto QSD-RF Driver is a 5 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 5 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 5 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%.
