Improved dynamic bridge standard as universal tool for bridge amplifier characterisation and calibration

Year: 2024

Type: article

Abstract: This paper presents the improved dynamic PTB bridge standard which now generates fully symmetrical output signals. It can be used for dynamic bridge amplifier calibration according to ISO 4965–2 and operates with all combinations of dc and carrier frequency bridge supply voltages together with simulated measurement signals that can be static, dynamic, or a combination of both. Furthermore, it can be used for bridge amplifier linearity investigations due to its good inherent linearity. Consequently, it is a universal tool for most bridge amplifier investigations and calibrations, respectively.
