Technology rapidly changing, the scope of the latest applications are endless. Oscilloscope manufacturers must follow the trend of new applications designed to meet the specific needs of users oscilloscope and software applications. This article will focus on 5 oscilloscopes market trends analysis.
Trend 1: The measurement from the parallel development to serial measurements.
Embedded design is usually the last parallel architecture, which means that each component has its own bus route.glue stick Therefore, if you can use the state pattern trigger or triggers to identify events of interest to you can visually decode the data on the bus.
However, the general design of modern embedded serial architecture - the continuous transmission bus data.glue gun The reason for this is that it requires less board space, lower cost, and using an embedded clock, and lower power requirements. Figure 1 shows the CAN data stream, which, inter embedded clock outside, CAN frame identifier information includes start address, data length code, data, CRC and the end of the frame identifier. This serial data analysis and trigger the data is usually much more difficult than the parallel.
Therefore, the oscilloscope manufacturers currently offer a variety of serial data triggering, search features and protocols observation procedures to help you find events that interest, and its decoding and measurements. For example, AgilentInfiniium90000A Series oscilloscope with serial data analysis software package to support a large number of protocols, including CAN, LIN, I2C, SPI, Flexray, SAS, SATA, XAUI, Fibre Channel, DVI / HDMI, Infiniband and PCI-express (1.1 and 2.0).
With the new generation of such agreement and the agreement to enter emerging markets, the scope of new technology suppliers must keep up the pace of development, allowing users to effectively use these agreements work.
Trend 2: mixed-signal oscilloscope.
Mixed Signal Oscilloscope (MSO) is more than a dozen years ago by HP / Agilent launched the first time. It is a comprehensive test instrument, with the availability of the oscilloscope, logic analyzer measurement capabilities, and some serial protocol analysis. Display in the MSO, you can view a variety of time-aligned analog and digital waveforms. Although the MSO logic analyzer can not provide all the channels available (MSO usually 2 to 4 analog inputs and about 16 digital inputs), but its use can make up for it. Logic analyzer is too complex to use, and the oscilloscope is relatively simple. This is the advantage of MSO - sets a variety of test equipment of the director, and in between them to find the perfect balance.
MSO is a popular technique for the current mixed-signal embedded systems created. For example, automotive electronic systems usually have digital control of analog motor controllers and sensors. In the past, people usually choose traditional oscilloscopes to analyze such systems, but often not enough to trigger the oscilloscope and the input channel capacity. Therefore, it must also use the logic analyzer, resulting in a more complex setup and operation.
MSO completely solve the problem, and proven, embedded mixed-signal system is to analyze the best equipment.
Trend 3: The powerful, portable oscilloscope / customized generic oscilloscope.
In the past, high performance oscilloscopes are huge size, portable oscilloscope performance and lower, and the user can only either. Modern design and high-speed serial data to an urgent need for many people a portable high-performance oscilloscope. AgilentInfiniiVision7000 Series oscilloscope should be born, although it is very small in size (6.5 inches deep and weighs 13 pounds), but with MegaZoomIII deep memory, to 100,000 waveforms / sec update rate, hardware-accelerated serial triggering and decoding.
This allows you to have a highly portable, high-performance oscilloscope.
At present, it is also increasingly used in many similar packages available in the oscilloscope to customize the general oscilloscope. Some software applications, such as the various serial decoding package, vector signal analysis (VSA) software, application software and power off-line viewing and analysis software, allowing users in a very personal way to customize and use their common oscilloscope .
Trend 4: The scope is more automated test tools used, instead of debugging tools.
In the past, engineers or technicians mainly for debugging and design of the oscilloscope, such as fault diagnosis of electrical components. Now, although there is still that the role of the oscilloscope, but with the automatic verification are becoming increasingly common - that is, check whether the device is a serial data standards to meet the technical requirements.
Areas of consistency, each with a serial data bus technology equipment must meet predetermined specifications to ensure that various manufacturers in different devices compatible with each other.
With the second and third generation standards emerge, more and more high data rate equipment, the oscilloscope eye diagram analysis of signal integrity and performance requirements also will be improved, and asked the oscilloscope to minimize the measured the impact of the system, because the high data rate conditions, these effects may be very serious. In addition, the industry has developed a consistency of application for automated testing of equipment. For example, Agilent offers a variety of consistency of application of consistent application, including the DDR (1,2 and 3), DVI, Ethernet, Fibre Channel, fully buffered DIMM, HDMI, USB, Wireless USB, PCIExpress, SATAI / II, XAUI and so on.
Trend 5: better display.
Users now need to better monitor, for many reasons. First, as social development, there is growing accustomed to using large, high resolution displays. Not long ago, using a small computer monitor or TV screen, the situation is still very common. Today, large LCD and plasma display shelves full of electronics stores - these everyday devices are equipped with sophisticated monitors performance, it is natural that there are other display devices like monitors. Therefore, many manufacturers have put into the oscilloscope equipped with large-size high-resolution display oscilloscope. For example, AgilentInfiniium90000A Series oscilloscope with high-resolution 12.1-inch XGA display.
The second reason is that people now need to simultaneously display on the oscilloscope for more signals, including analog data signals and digital data signals, the oscilloscope must be equipped with a display big enough to display all waveforms. In addition, the display must also have sufficient resolution and color, so that users clearly distinguish each waveform and decode the tag read. AgilentInfiniiVision7000 256 Series oscilloscope with a 12.1-inch XGA display brightness, is an excellent display quality can provide a portable oscilloscope.
Oscilloscope is mainly used for testing and development of modern technology, to be flexible to adapt to new environments. The main purpose of the oscilloscope is constantly changing. Oscilloscope suppliers to make customer satisfaction and efficient completion of work, you must continue to introduce new products to adapt to this development.
