Keywords: digital data acquisition systems, analog-to-digital converter, performance testing
Аnnotation: The paper discusses one of the possible methods for testing in field conditions the performance of almost any geophysical digital data acquisition systems (DAS). Today, almost the entire range of geophysical observations is carried out in digital format. For this purpose, a wide variety of DAS are used. The basis of all such systems is analog-to-digital converters (ADCs), which can be implemented in the form of both microchips and independent electronic units or boards. Unfortunately, often during field work, expedition participants and geophysicists do not pay due attention to periodic monitoring of the correct functioning of the used ADC or DAS and prompt as-sessment of the quality of their work. Periodic testing of the DAS is an important stage in the practical operation of such systems, since it ensures quality control of analog-to-digital conversion and determines the reliability of the system as a whole. This issue becomes especially acute when carrying out work far from civilization, where there is fundamentally no expensive and often heavy and complex service equipment. DAS testing is a compre-hensive process of checking used ADCs for compliance with the required parameters. Testing may include con-version accuracy, linearity, resolution, noise, drift, conversion time, and other characteristics. Various methods and tools can be used for verification, such as calibrators, signal generators, oscilloscopes and measurement equipment. However, in the field, all this equipment turns out to be unavailable. This paper proposes the sim-plest ways to test the performance of almost any DAS and ADC. It is shown how, using the simplest equipment and devices, you can make an initial assessment and verification of the quality of their work and functioning.
