The Model 609E-6 is a DC-stable, high-voltage power amplifier used in industrial and research applications. It features an allsolid-state design for high slew rate, wide bandwidth and lownoise operation. The four-quadrant, active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range. This type of output is essential to achieve an accurate output response and high slew rate demanded by a variety of loads such as highly capacitive or reactive loads. It is configured as a non-inverting amplifier, an inverting amplifier or as a differential amplifier. Different input configurations can be wired into the unit.
