The Portable Data Acquisition System (DAS) 4U is an integrated data acquisition system for cased-hole well logging. It collects and processes logging data using mono-conductor cable, displays in the form of graphs or curves and conducts online interpretation of some products.
The DAS has two-way transmission function and adopts USB for higher transmission rate. Modular design with more detailed and independent division of each functional module improves expandability. The bus board is customized and necessary buffer and network resistance are added for increased reliability. The Digital Signal Processing (DSP) and Complex Programmable Logic Device (CPLD) form the main control functional module.
