Why use a Preamplifier Module?
Unlike desktop-amplifiers, preamplifier modules provide gain close to the detector before the signal-to-noise ratio significantly decreases due to cable capacitance and noise pickup. Signal processing and measuring after preamplifying has no effect on the signal/noise performance. Gain and Noise In order to achieve an extremely low noise performance in the LCA current amplifier very high gains were chosen, while nevertheless minimizing the associated bandwidth reduction. Thus, as a result of our sophisticated development efforts, we can offer a professional “High-End” current amplifier line. The noise performance of our products surpasses by far that of conventionally designed OpAmp-current-to-voltage converters at the corresponding bandwidth. Bandwidth and Frequency Response FEMTO ultra low-noise current amplifiers show almost ideal behavior without the need for special adaptations or frequency compensations. Bandwidth and frequency response are independent of source capacitance up to
