Description
Functions
The BELEKTRONIG SAW generator BSG is used to control SAW actuators at professional applications in acoustofluidics. It integrates network analyzer, frequency generator, power amplifier and meter in a compact device. It therefore replaces the cost-intensive and complex setups that have been necessary for SAW actuators so far. The SAW actuators are controlled by a high frequency alternating voltage with variable frequency and amplitude. The optimum excitation frequency is automatically tracked and adjusted in case of deviations.
Additional Functions
A variety of other functions have been implemented specifically for R & D projects in the area of Acoustofluidics. The dual-channel version offers a possibility to synchronize frequency, amplitude, and phase. This allows to easily generate standing waves for acoustic tweezers. The Trigger I/O can be used, for example for controlling external cameras.
