Trek 677B High-Voltage Power Amplifier - Manual

The Model 677B is a high-voltage power amplifier/supply designed to
provide precise control of output voltages. It can be operated in one of
two modes: as a high-voltage amplifier when it is configured as a
noninverting amplifier with a fixed gain or as high-voltage power
supply that responds to front panel controls to command exact output
voltage or current.
The 677B features an all-solid-state design for wide bandwidth, high
slew rate 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.
