Features: Models with different input stages cover an amplification range from 20 dB (×10) to 100 dB (×105). As usual, four amplification levels are available for different signal levels. There is a choice of bipolar input stages with an impedance of 1 MΩ for low-impedance sources and FET input stages with an impedance of 1 TΩ for high-impedance sources. Models with a symmetrical (true differential) input allow the measurement of differential signals. All models have switchable AC coupling and a bandwidth of 100 kHz, switchable to 1 kHz. Thanks to their high-quality construction, the robust amplifiers can work easily even in areas with strong electromagnetic interference. They are easy to use and can be controlled completely manually or via a digital interface (USB optional).

Applications: The “DLPVA-101” models are excellently suited as universal low-frequency amplifiers in a wide range of applications. They are ideal as detector preamplifiers, for signal acquisition of industrial sensors and as an assembly of integrated measuring systems.
