Elementary Knowledge of Electronic Tester

Concept of Electronic Tester
Electronic instruments are including electronic measuring instruments and electronic appliances, and they measure by using electronic technology, observation instruments, devices and systems of the power non-electricity, or for measurement purposes and the supply of light, electricity, and measurement accessories. The measurements include data acquisition, storage, display, printing, graphic, processing and transmission and other information products. Types and Ranges of Electrical Testers Basic instruments and general instruments: they are more used in the digital multimeters, power supplies, function generators, counters and plug socket tester. RF and microwave instruments and systems: spectrum analyzers, network analyzers, signal generators, power meters, noise figure analyzers, oscilloscopes, logic analyzers and digital test: oscilloscope, logic analyzer, the simulation trace port analyzer, BERT. Test and measurement software and connectivity: test and measurement tools set, VEE, TestExec SL IntuiLink, IVI, connectivity ... test systems and system components: functional testing, VXI data acquisition for the construction of parts of the test system and software. Lightwave instruments and systems: optical component testing, optical wave converter, communication analysis analyzer (DCA), wavelength meter, light switch. Semiconductor test equipment: memory test, wafer parametric testing, system-on-chip (SOC) test, RFIC testing. Test and measurement accessories, cabinet, cable: cabinets, cables, probes, test vehicle, Rackmount kit. Major Technology Trends of Electrical Tester Now the electrical test equipment and systems are in a period of multi-bus interface coexist chaos. Special large-scale integrated circuits and programmable devices are commonly used instrument which not only protect their own patents, and more important to change the ideas and design of digital circuits and computer systems design. Computer systems and the use of LSI, completely changed design ideas of people, high demands on the designers and, more important, the test instrument can directly adopt the latest achievements of the computer, so that the replacement rate of the instrument with the computer to maintain synchronization. Overall technical level of domestic testing instrument: Universal benchtop: microwave and millimeter wave instrument categories basically have complete varieties, broadband coaxial instrument is up to 40GHz to 110GHz millimeter-wave waveguide instrument; complete range of fiber optic instruments; communication instrument test rate is 2.4Gb / s; data acquisition instrument digitization rate is up to 1GSa / s and a bandwidth of 500MHz. The VXI bus modular test instruments: VXI test module type spectrum series has begun to take shape, the automatic test system can be used for the formation of the radio-frequency, low frequency and data acquisition. Automatic test systems and fault diagnosis: a number of practical test system developed and successfully applied to the development, production and maintenance of weapons and equipment testing, circuit board fault diagnosis system to achieve a breakthrough.
