Current sweep power oscillator (CSPO-1) was designed to develop, on the surface of a quartz resonator, an acceleration up to 100 million times the gravitational acceleration on the Earth. This is interesting in fundamental physics, materials science and  biotechnology.
The acceleration developed by the shear vibration of the quartz resonator induces a sedimentation of the atoms and molecules on the quartz resonator surface. The associated out-of-plane vibration, in two small lobes along the x-axis of the quartz resonator, induces an expelling of the particles from these lobes breaking the bonds and creating a separation effect.

CSPO-1 can drive quartz crystal resonators with different driving levels. The crystal current (RMS) can be adjusted within large limits from 0.1 mA to 100 mA in two ranges:

     A.  From 0.1 mA to 5 mA
     B.  From 2 mA to 100 mA

The maximum power delivered by the quartz resonator is 100 mW.
Crystal current can be swept within each range with different rates.
The standard frequency range is from 4.6 MHz to 11 MHz. Other ranges are available on request.
Tuning within the specified range and adjustment of the negative resistance of the oscillator are possible.

Power supply: 24 V DC, 0.5 A (wall type)
