Signal amplifier 9200A

power2-channelcurrent output

Model 9200A was designed as a general purpose, wide band and high voltage amplifier however, with specific applications in mind. It is built in a small case size to save space and cost but without compromising bandwidth and signal integrity. Full power bandwidth from DC to >500kHz Features Solve Common Problems Model 9200A can output signals from -200V to +200V with continuous currents up to 100mA per channel. The output is driven from a 0.1Ω source and, with some degradation of its bandwidth, can drive capacitive loads up to 1nF, while maintaining its full amplitude range. Model 9200A has a rear-panel monitor output that divides the main output signal by 100 for applications that require monitoring of the output signal with low voltage sensors. Modes of Operation The 9200A has two modes of operation. The first is normal mode where each channel amplifies and outputs bipolar signals with a gain of x50. In this mode, the input signal is amplified and delivered to the output terminals without modification of its original properties, except its amplitude level. Using this mode of operation, each channel can be used separately to amplify a unique signal. The second mode of operation is the unipolar mode where the signal is applied to one input, rectified, amplified and output through two separate outputs. Using this mode, the amplifier is converted to a one-input, two-output system, specifically designed to operate the up/down and right/left actuators of a typical MEMS micro engine, as well as for other applications requiring the precise conversion of bipolar to unipolar signals.
