The ED driver is configured to operate a broad range of resonant optical scanners and resonant optical choppers at their natural frequency. The ED driver amplifies the pickup coil signal from the resonant device and returns the amplified signal to the drive coil. This positive feedback loop is user controlled by an amplitude limiting trim pot. The ED driver also provides a monitor output square wave reference output signal and is amplitude control adjustable over a range of 5:1 min.

The ED type driver is available in for driving SC type resonant scanners and CH type resonant choppers.
