Handheld multifunctional parallel-operation measuring device

Abstract

The invention discloses a handheld multifunctional parallel-operation measuring device, which comprises a field programmable gata array (FPGA) and a microprogrammed control unit (MCU), and further comprises an oscilloscope analog front end I, an oscilloscope analog front end II, a multimeter analog front end, an excitation generator, a storage, a power supply manager, a rear end regulator, a high-accuracy analog to digital Converter (ADC) and a plurality of high-speed ADCs. The MCU is communicated with the FPGA in two-way mode, the storage is communicated with the FPGA in two-way mode, and the power supply manager is communicated with the MCU. Compared with an existing device, a system is composed of the MCU and the FPGA along with necessary peripheral input and output signal chains and the efficient power supply manager, the FPGA achieves various high-speed functions, users do not have to passively purchase a plurality of devices with a single function according to test requirements, and a plurality of test modules with a single function are integrated. The measuring device is also capable of achieving simultaneous work of all measuring functions and has the advantages of being high in measuring and testing accuracy, small in size, low in power consumption, convenient in date exchange and user-friendly in man-machine interaction interface.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a hand-held multifunctional measuring instrument operated in parallel. Background technique [0002] At present, traditional signal test and measurement instruments often only have a single function, but the measured signals encountered in actual work are various and complex, and more than one test and measurement instrument is required. low cost, cumbersome data exchange, and inconvenient human-computer interaction interface. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the purpose of the present invention is to provide a hand-held multi-functional parallel-operated measuring instrument that solves the above-mentioned problems. [0004] For realizing above-mentioned purpose of the invention, the technical scheme that the present invention adopts is as follows: [0005] A hand-held multi-functional parallel operation measuring instrument...
