Tabor Electronics 9100A-DST 400Vp-p Single Channel Signal Amplifier

The 9000A-DST series was designed as a general-purpose wide band and high voltage amplifier having specific applications in mind. It has up to 4 channels built in a small case size to save space and cost without compromising bandwidth and signal integrity. The 9000A-DST series can output signals from -200V to +200V with continuous currents up to 125mA. The output is driven from a 0.1W source and, with some degradation of its bandwidth, can drive capacitive loads up to 1nF while maintaining its full amplitude range. The series has rear-panel monitor outputs that divides the main outputs signal by 100 for applications that require monitoring of the output signal with low voltage sensors. 

Modes of Operation
The 9000A-DST 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, which can be used separately to amplify a unique signal, without modification of its original properties except its amplitude level. 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.
Target Applications
The 9000A-DST is an ideal solution for virtually any high-voltage, wide-band application, from MEMS micro engine, to any other applications requiring precise conversion to unipolar signals.

Safety
Safety played a major role during the design of the Model 9000A-DST. The high voltage path to the amplifier circuit is blocked by a front panel mechanical switch and accidental application of high power to the UUT is prevented by a safety latch. The 9x00A will output high voltage signals only after the safety latch has been lifted and the high voltage switch flipped to ON position. In emergency situations, one can hit the protective latch to immediately remove the high voltage power from the output terminals. As an additional visual safety feature, a red light glows on the front panel whenever the high voltage is turned on.
