Abstract

The invention discloses a multifunctional virtual electronic instrument, which comprises the functions of a digital oscilloscope, a signal generator, a DC voltage source, a DC voltmeter, a frequency characteristic analyzer and a logic analyzer. The multifunctional virtual electronic instrument comprises a human-machine interaction module, an ARM control module, an input signal regulating module, a DDS module, an output signal regulating module, a power supply module, and a debugging module. According to the instrument of the invention, the strong data processing ability of a computer is utilized; the hardware circuit size is reduced; the consumed material cost is reduced; the circuits are more integrated; and therefore, the instrument becomes portable to carry and convenient to use. The instrument further overcomes the limitation that a traditional electronic testing instrument can only be used in laboratories. Therefore, the students could use it for testing at any time and any place. The students are entitled to the largest freedom to do so, and a completely open laboratory in true sense comes into being.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to a multifunctional virtual electronic instrument. Background technique [0002] With the rapid development of computer technology, integrated circuit technology and electronic measurement technology, electronic measuring instruments have been widely used in scientific research, experimental teaching and industrial production. Due to the high cost, low integration, bulky size, and inconvenient portability of traditional electronic measuring instruments, their further development and application are hindered. A solution is urgently needed to improve the shortcomings of existing electronic instruments. [0003] Compared with traditional instruments, the main advantages of virtual instruments lie in the flexibility and powerful functions of applications. In a virtual instrument, hardware is used only for signal input and output. This not only reduces the use of components, save...
