The Five Major Trend Analysis Oscilloscope Future Development Space
- Apr 23, 2018 -

The latest application of oscilloscope is endless. The oscilloscope manufacturer must keep up with the new application trend and design an oscilloscope and software application that can meet the user's specific needs. This paper will analyze five trends in the oscilloscope market.

Trend 1: development from parallel measurement to serial measurement.

The embedded design of the past usually USES a parallel architecture, which means that each bus component has its own path. Therefore, as long as you can use the code type trigger or state to find the event of interest, you can intuitively decode the data on the bus.

However, modern embedded design generally adopts serial architecture -- that is, continuous transmission of bus data. The reason for this is that it requires smaller circuit boards, lower costs and lower power requirements with embedded clocks. Figure 1 shows CAN data flow, in which the CAN information includes the beginning, address, length code, data, CRC and frame identifier of the frame identifier. Analyzing and triggering this serial data is usually much more difficult than parallel data.

As such agreements continue to emerge and a new generation of agreements enters the market, oscilloscope suppliers must keep up with the pace of new technologies to enable them to work effectively with these protocols.

Trend 2: mixed signal oscilloscope.

The hybrid signal oscilloscope (MSO) was first introduced by HP/agilent technologies more than a decade ago. It is a comprehensive test instrument with the availability of oscilloscope, the measurement capability of the logic analyzer and some serial protocol analysis functions. On the MSO monitor, you can view a variety of time - arranged analog and digital waveforms. Although MSO fails to provide all the channels that the logical analyzer can provide (MSO usually has 2 to 4 analog inputs and about 16 digital inputs), its use can make up for that. Logic analyzers are too complex to use, and oscilloscopes are easier to use. This is the advantage of MSO - the ability to set up a variety of testing devices and find the perfect balance between them.

MSO is created for embedded hybrid signaling systems that are popular in current technologies. For example, automotive electronic systems usually have digital controlled analog motor controllers and sensors. In the past, traditional oscilloscopes were used to analyze such systems, but the oscilloscope often did not have enough trigger and input channels. Therefore, people must also use logic analyzers, and the results make setup and operation more complex.

MSO completely solves this problem, and it is proved to be the best instrument for analyzing embedded mixed signal system.

Trend 3: powerful portable oscilloscope/customized universal oscilloscope.

In the past, the oscilloscope with high performance was bulky, and the oscilloscope with easy to carry was low, and the user could only one of them. Modern high speed design and serial data make many people urgently need a portable high performance oscilloscope. AgilentInfiniiVision7000 series oscilloscope should be born, although it is small size (6.5 inches deep, 13 pounds), but it has MegaZoomIII deep memory, 100000 waveform/SEC update rate, serial trigger and decoding function of hardware acceleration.

At present, people are increasingly using the software packages provided in many similar oscilloscopes to customize their universal oscilloscope. Some software applications, such as a variety of serial decoding software package, the vector signal analysis (VSA) software, power applications and offline viewing and analysis software, users can be used in a way that is very personalized customization and their general oscillograph.

Trend 4: the oscilloscope is being used more as an automatic inspection tool than as a debugging tool.

In the past, engineers or technicians mainly used oscilloscopes for debugging and design work, such as diagnosing faulty electrical components. Now, although the oscilloscope still has this role, it is becoming increasingly common to use automatic verification -- that is, to check whether the device meets a technical specification for a serial data standard.

In the conformance domain, each device that USES a serial data bus technology must meet the intended technical specifications to ensure that the different devices made by each manufacturer are compatible with each other.

With the emergence of second and third generation standard, equipment data rate is higher and higher, the signal integrity of the oscilloscope and eye diagram performance demand increases, and requires the oscilloscope to reduce the influence on the system under test, because under the condition of high data rate, these effects can be very serious. In addition, the industry has developed a consistent application for automated testing of devices. Agilent, for example, for a variety of consistent application provides a consistent application, including the DDR (1, 2, and 3), DVI, Ethernet, fibre channel, full buffer DIMM, HDMI, USB, wireless USB, PCIExpress, SATAI/II, XAUI and so on.

Trend 5: better displays.

Users now need better displays for a number of reasons. First of all, with the development of society, people are increasingly accustomed to using large-size, high-resolution displays. Not long ago, it was common to use small computer monitors or TV screens. Now, big LCD and plasma display with electronics store shelves - for the daily use of equipment are equipped with excellent display performance, people naturally want to show other instruments have a display like that. As a result, many oscilloscope manufacturers are producing oscilloscopes with large-sized high-resolution displays.

The second reason is that people now need more signal on the oscilloscope display at the same time, including the simulation data signals and digital data, therefore the oscilloscope must be equipped with a large enough to properly display all waveform. In addition, the monitor must have high enough resolution and color so that the user can clearly distinguish each waveform and read the decoding mark. The AgilentInfiniiVision7000 series oscilloscope is equipped with a 12.1-inch XGA display with a 256 level brightness. It is a portable oscilloscope that can provide excellent display quality.

The oscilloscope is mainly used for testing and developing modern technology, so it must adapt to the new application environment very flexibly. The main use of the oscilloscope is constantly changing. Oscilloscope suppliers must constantly introduce new products to adapt to this development if they want to satisfy and efficiently complete their work.
