The new DLPVA-101-B, -F and -BLN models are sensitive voltage amplifiers for the precise measurement of small voltage signals. They replace the corresponding DLPVA-100 variants and are characterized by significantly lower noise, in some cases by an order of magnitude, while the range of functions and operation remain identical.
Models with different input stages cover an amplification range from 20 dB (x10) to 100 dB (x105). As usual, four amplifications are available for different signal strengths. 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 balanced (true differential) input also 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 design, the robust amplifiers can also operate without problems in areas with high electromagnetic interference. They are easy to operate and can be controlled completely manually or via a digital interface (USB optional).
All DLPVA models are ideally 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 modules of integrated measuring systems.
