Trek Model 609E-6-FG High Voltage Function Generator is a combination of a DC-stable high voltage amplifier and a function generator.

The high power amplifier is designed to provide precise control of bi-polar output voltages in the range of 0 to ±4 kV DC or peak AC with an output current range of 0 to ±20 mA DC or peak AC. The function generator is capable of generating square, triangle and sine waveforms in the frequency range of 0.2 Hz to 10 kHz. In the amplifier mode, the 609E-6-FG can be configured as a non-inverting, inverting or differential amplifier with a fixed gain of 1000 V/V.<

Trek Model 615A-1 and Model 615-3 are precision high voltage AC/DC generators that can be used in both R & D and production operations.

They are specifically designed to simultaneously provide AC and DC operation potentials required to operate or control an "Electrostatic Charger Roller". Electrostatic Charger Rollers are used in electrostatic photocopier and digital printing systems. They have three modes of operation: Constant Voltage, Constant Current, or External Amplifier mode.
