acousto-optic RF driver

The acousto-optic driver provides an RF source for acousto-optic modulators (AOM) and frequency shifters (AOFS) and converts electrical signals into ultrasonic signals through piezoelectric transducers. High signal frequency stability (customizable), low power consumption, and output power less than 3W. The frequency and intensity of the RF signal generated by the driver determine the degree to which the beam is modulated, deflected, or tuned. In addition, the product adopts an all-metal structure, which helps with heat dissipation and further improves the temperature stability of the driver, ensuring the reliable operation of the product.

Supporting DriveThe SGXXXX-33-N-ab model is a versatile signal generator with a range of features denoted by its unique code. The letters “X,” “Y,” and “T” represent its frequency shift function, modulation capabilities, and additional modulation functionality, respectively. The “XXX” portion of the code specifies the operating frequency, while “33” indicates the RF output power. The package type is designated by the letter “N,” and the power supply voltage (24V or 12V) is determined by the letter “A.” Finally, the modulation type is defined by the letter “b,” where “D” stands for digital TTL modulation and “A” represents analog modulation.
