Trek 609E-6 User Manual
Trek Model 609E-6
High-Voltage Power Amplifier
The Model 609E-6 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 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.
