【正文】 ams integrated environment to realize the concept of a VI. NI39。s Software Instrument (Softwareisinstrument) pletely broke the traditional instruments can only be given by the manufacturer the user can not change the situation.C. Highly intelligent With cuttingedge technology (such as aerospace, weapons engineering) and highrisk project development needs of electronic measurement technology increasing degree of intelligence. But in recent years the field of embedded puter technology development to enhance the intelligence of electronic measuring instruments provide good conditions. Emerging in recent years, such as embedded chip FPGA, ARM, CPLD, etc., they are a highreliability, high stability, fast immediately applied to electronic measuring instruments. The microputerbased processing technology microprocessor allows the measurement methods of measuring instruments diversification measure realtime and highly intelligent.Ⅳ. DDS technology development history In the traditional field of electronic measurement and instrumentation, PLL Frequency Synthesizer (PLL) is the most monly used frequency co into technology. As electronic measurement and instrumentation industry continues to develop, for frequency synthesis techniques are increasingly high requirements. 2Oth emerged in the midcentury direct digital frequency synthesis (DDS) is an alldigital frequency synthesis technology, due to its special principle and structure, so that in electronics, munications, access to a growing range of applications. In the field of electronic measurement and instrumentation, DDS The main applications include: audio testing, product testing, the instantaneous power signal reproduction, shock and vibration test, medical test equipment, conventional waveforms and arbitrary waveform generator, high precision, multifunction modulation etc.Ⅴ. Conclusion In summary, in the 21st century electronic measuring instruments with chip technology and DSP technology will reach an unprecedented high performance, with puter technology and the further integration of the instrument, the instrument39。s ease of operation, easy scalability, measurement capability, the number of data processing and analysis capabilities have been greatly improved. At the same time, software engineering and network technologies are increasingly being applied to various fields, development of simulation technology as well as electronic measurement provides a more powerful and convenient tool. In short, the electronic measurement technology development is a multidisciplinary, multifield development cocrystallization, while between them for each other and mutual service of with the development.7
