Trek 20-20C High-Voltage Power Amplifier - Manual

The Model 20/20C is a DC-stable, high-voltage power
amplifier used in industrial and research applications
. It
features an all-solid-state design for high slew rate, wide
bandwidth and low-noise 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.
