SAW GENERATOR BSG

The SAW Generator BSG F20
Always part of scope of delivery, the PC software BSG Soft

description

function

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.
