The oscilloscope will go to large-size high-definition screen display more accurately

Industrial Control Abstract: In the industrial field, electronic measuring instruments are widely used. No matter sensors, inverters, controllers, monitors, etc. are all very important applications, in these devices, the oscilloscope can become the eyes of engineers, it can display at any time. The voltage change situation can efficiently find out the fault and ensure the normal operation and play of the electrical equipment.

Oscilloscope definition and working principle

The so-called oscilloscope is to convert the invisible electric signal into a visible image, which is convenient for people to study the changing process of various electric phenomena.

The working principle of the oscilloscope is that it uses a narrow, high-speed electron beam composed of electrons, hit the screen coated with fluorescent substances, it can produce a small spot. Under the action of the signal under test, the electron beam is like a pen tip, which can depict the curve of the instantaneous value of the measured signal on the screen.

Using an oscilloscope, you can observe the waveform curves of various signal amplitudes over time, and you can also use it to test various power levels, such as voltage, current, frequency, phase difference, amplitude, and so on.

New oscilloscope: Extended display for extended display

Recently, LeCroy has launched two WaveAce1000 and 2000 WaveAce oscilloscope series products. Compared to traditional oscilloscopes, WaveAce oscilloscopes are equipped with a 7-inch ultra-wide display and powerful debugging tools such as 32 automatic measurements, waveform math capabilities, pass/fail tests, large internal storage, remote control, and waveform recorders. The combination of a logic analyzer and a waveform generator provides expanded debugging and testing capabilities.

Agilent Technologies Inc. Announces Six New Generations of Infiniium 9000 Series Oscilloscopes with Industry's Largest 15-inch (38.1-cm) XGA LCD Display, Up to 4GHz of True Analog Bandwidth, Excellent Oscilloscope Performance, and Built-in Logical analysis and protocol analysis capabilities provide the widest range of measurement capabilities.

Oscilloscope development trend: large-size high-definition screen

The ultra-wide 7-inch display of the WaveAce oscilloscope series allows us to see the trend of the oscilloscope in the future, namely the large-size high-definition screen. Today, large LCD and plasma displays flood the electronics store's shelves—these everyday-use devices are equipped with high-performance monitors that are evolving to large screens, and oscilloscopes are no exception. Therefore, many oscilloscope manufacturers have started production of oscilloscopes equipped with large-size high-resolution displays. For example, the Agilent Infiniium 90000A Series oscilloscopes come with a 12.1-inch XGA high-resolution display.

In addition to the above reasons, people need to display more signals on the oscilloscope at the same time, including analog data signals and digital data signals. Therefore, the oscilloscope must be equipped with a large enough display to correctly display all waveforms. In addition, the display must also have a sufficiently high resolution and color so that the user clearly distinguishes each waveform and reads the decoded signature.

summary:

As an electronic display instrument, oscilloscope has a very important significance for the research of electronic devices. With the development of society, the oscilloscope will also develop toward a more intelligent and high-level direction. With the oscilloscope of the 12th Five-Year Plan in China, the oscilloscope will usher in a steady increase in demand, while the manufacturers are still in the low-end level, in urgent need of upgrading, according to different areas of research and development of different characteristics of the oscilloscope is a top priority, we hope in In the near future, you can see the emergence of high-end products in China's oscilloscope products.
