Amplifier AQ08-01

Purpose:

Converting high-impedance charge signal from piezoelectric transducers to a low-impedance voltage signal.

Features:

Low intrinsic noise.
Can be used at long communication lines (up to 100 m), almost without reducing sensitivity or limiting the low frequency region.
Normalization mode.
Measurement report.
Operating mode control via USB port.
