What does an oscilloscope do?
Oscilloscope is a kind of instrument which is widely used to display the trace change of instantaneous value measured.It can transform the electric signal invisible to the naked eye into visible image, which is convenient for people to study the change process of various electric phenomena. An oscilloscope USES a narrow beam of high-speed electrons to produce tiny points of light by hitting a surface coated with fluorescent material. Under the action of the measured signal, the electron beam ACTS like the tip of a pen and can plot the instantaneous value of the measured signal on the screen.Use oscilloscope to be able to observe all sorts of different signal amplitude the waveform curve that changes with time, still can use it to test all sorts of different electric quantity, if voltage, current, frequency, phase difference, adjust amplitude to wait a moment.
Digital oscilloscope automatic verification system
With the development of electronic technology, digital oscilloscope with the digital technology and software greatly expanded the ability to work, the early products of low sampling rate, there is a big dead zone time, less than be improved screen refresh rate low, difficult to observe before modulation signal, communication eye diagram, such as composite video signal is more and more easy to observe. Digital oscilloscope can calculate and analyze data, which is especially suitable for capturing all details and abnormal phenomena in complex dynamic signal.In order to make the oscilloscope work in a qualified state, it is an urgent task for the test engineer to verify the oscilloscope regularly, quickly and comprehensively and to ensure the traceability of its value.
Manual verification is inefficient and prone to errors. The verification of each oscilloscope requires the test engineer to read a lot of data.The automatic test system has the characteristics of accurately and quickly measuring parameters, intuitively displaying test results, automatically storing test data and so on.It will be the trend of instrument verification to realize program control verification of oscilloscope with automatic test system.
GPIB, VXI and PXI are the standard buses of automatic test system. GPIB has won the recognition of users for its stable performance, convenient operation and low price.Here, GPIB is selected as the bus of the test system.
The hardware of automatic verification system of digital oscilloscope based on GPIB is composed of GPIB controller, FLUKE5500A, verified digital oscilloscope, PC and printer
