摘要
Abstract
The electrical signal generator is independently developed by CGE(Chongqing)Geological Instrument Co.,Ltd with modular design,including a single-chip microcontroller control module,a power chip module and a signal generation module.In this signal generator,power stability and low noise interference is ensured with multi-stage voltage regulator circuit,and stable standard voltage signals is output through low-temperature drift & low-noise reference source,active filter and passive filter.It is possible to make judgments on whether the measurement results of induced polarization receiver and DC electrical instrument meet the requirements technical specifications during debugging and inspection stages.关键词
