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

The Model 20/20C-HS is a DC-stable, high-speed, 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.
