Trek 623B High-Voltage Power Amplifier - Manual

The Model 623B is a DC-stable, high-voltage power amplifier
designed to provide precise control of bi-polar output voltages. It
features an all-solid-state design for high slew rate, low-noise
operation and a wide bandwidth of DC to greater than 10 kHz .
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.
