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.

Trek's Model 20/20C-HS offers 3x peak current, higher slew rate and bandwidth compared to the model 20/20C.
