This device is a combination of a high-voltage power amplifier and a programmable digitally controlled waveform generator.

The amplifier is able to provide an output power of about 1 kVA to loads with a significant capacitance. The output terminals produce voltages which are symmetrical with respect to ground. The total output voltage is almost unipolar and ranges from 0 to 1.1 kV.

The waveform generator can produce preferably harmonic signals or a combination of them in a frequency range of up to several kHz. The signal output can be synchronized with external devices via the trigger input.

The device is equipped with an interlock loop that disables and shorts the output if it is opened. The device also contains circuitry that scans the temperature measured by an external Pt1000 sensor.

The waveform generator is equipped with a USB data interface that allows the user to transfer waveform data to or from the device. To check the output signal of the amplifier, two monitor outputs are available.

The amplifier and its power supplies are linearly operating circuits. The emission level of electromagnetic radiation is therefore very low.
