[Introduction]It is definitely unrealistic to stare at the oscilloscope screen for a long time to observe the occasional abnormal signal that is a headache. So, what are the efficient ways to capture such signals? Segmented storage, application born.
What is segmented storage
The segmented storage is triggered multiple times during the acquisition process, and the data sampled for each trigger is stored in a small storage that divides the storage space into segments.Oscilloscope trigger fills one segment at a time, idle signals or signals between segments are not interestingInteresting parts are not captured and stored.
The principle is shown in the figure below: the total storage depth is divided into n segments, the first segment is used for Display, and the second segment starts to store, that is, the data collected when the first trigger occurs is stored in the second segment storage space, when the After the second segment storage space is full, end the first trigger, wait for the second trigger, and store the data in the third segment storage space after triggering, and so on.
Segmented storage structure diagram
If the total storage depth of the oscilloscope is 512Mpts, the calculation formula of segment allocation is as follows:
N=512*1024*1024/[The current storage capacity is rounded to the power of 2n]-1
How to set up segmented storage
The maximum storage of ZDS5000 series oscilloscope is 512Mpts, while maintaining the sampling rate of 4GSa/s, it supports segmented storage range: 1~524287 segments. Click[Seg]by adjusting the time base gear, in the state of 560Kpts storage depth, it will be divided into 255 segments for storage and acquisition, as shown in the figure below.
Staging storage settings
Set the trigger mode to[Normal]adjust the trigger level to an appropriate position, and wait for a small probability abnormal signal to arrive.
By touching the probe with your finger, you can simulate the occurrence of a small probability abnormal signal. After the segment storage is completed, click[Stop]click[Current Segment]and you can view all segment storage by rotating the knob A/B, as shown in Figure 20.4. Waveform stored for segment 45.
segmented storage results
Segmented storage applications
1. Low duty cycle pulse or burst signal – there is a long idle time between signals. In many cases, even if there is a large storage, it is difficult to achieve the desired acquisition time by reducing the sampling rate. , and segmented storage can be done well.
Low duty cycle pulse signal
2. Serial bus analysis – The serial bus is transmitted in the form of data packets, and the idle time between packets will occupy the precious storage resources of the oscilloscope. With segmented storage, the oscilloscope can only collect data packets and not sample in idle time. . While maintaining a high sampling rate, more data packets can be collected to facilitate decoding and analysis.
Example application: 8-hour oscillation detection test
Take the ZDS5000 series oscilloscope to test the connector for vibration test as an example. During the whole test process, monitor the number of possible secondary failure areas of the connector, and then check whether the product is qualified.
1. Test requirements
The entire vibration test lasts 8 hours. During the whole process, the connector may have 0 to dozens of failures. The duration is more than 300ns, and the amplitude is uncertain (normally, the level is 1V).
2. Difficulties in testing
● The duration of the vibration test is 8 hours, and the oscilloscope is difficult to record waves based on a large time base, and the sampling rate is not enough;
● The vibration laboratory has large noise interference, and the peak waveform and clutter during failure are mixed together, so it is not easy to test the signal in the failure area.
For the above test problems, the segmented storage function of the ZDS5000 series oscilloscope provides a good solution.
First, according to the characteristics of the abnormal signal, set the trigger conditions for the oscilloscope to capture (including trigger level, trigger mode, time base, segment storage, number of segments, etc.), conduct 8-hour vibration test monitoring, and capture the abnormal situation as shown in the figure shown:
As shown in the figure, in the 8-hour test period, a total of 380,404 abnormal waveforms were captured. The above picture shows the abnormal situation and signal characteristics of the failure area of the 281st segment. The current sampling rate is still 4GSa/s.
A critical and unpatched remote code execution vulnerability in Schneider Electric’s programmable logic controllers (PLCs) could allow attackers to take control of its various industrial systems, Armis security researchers have warned.
Schneider Electric’s line of Modicon controllers was one of the first PLC products on the market, and its function was to connect industrial equipment, from oil and gas pipelines to manufacturing systems and water purification facilities, into a network. But the study found a more serious vulnerability in the product: that could allow anyone to take control of the device by using hidden commands to bypass authentication.
“Armis researchers discovered that these commands can be used to take over a PLC and gain native code execution on the device that can be used to change the operation of the PLC while hiding changes from the engineering workstation that manages the PLC. This attack is an unidentified attack. An authenticated attack requires only network access to the target PLC,” said the information security analyst.
The vulnerability, dubbed “ModiPwn,” is claimed by Schneider Electric to be patched. Armis researchers have found that these patches only work if an app password is set, and we’ve found multiple ways to bypass the password, allowing everyone to open it again, even on the latest software versions this loophole.
To make matters worse, the vulnerability, originally classified as causing a denial of service (DoS) attack, was found to allow remote code execution — meaning an unauthenticated attacker could take full control of the PLC and, in turn, any software it uses. Industrial equipment.
Schneider Electric confirmed the vulnerabilities and promised to release a patch by the end of the year. However, for Schneider Electric customers, even with the patch installed, the devices need to be further verified to be safe.

Although low-code is currently surging in the market, and although many domestic manufacturers have promoted the concept of low-code on a large scale since 2019, in actual development cases, many companies are still taking the “old way”, and many companies in the industry spend a few An enterprise that finally completes only one product solution after spending millions of dollars a year. Many financial institutions rely on old systems and traditional development methods for many years, which leads to a series of problems, such as dependence on technology outsourcing companies, gaps between business teams and IT teams, project delays, and so on.
The emergence of low-code development platforms has allowed financial institutions to develop applications, websites, user interfaces and other digital experiences 8-10 times faster. Siemens Low Code is a high-productivity application development platform that turns development into a highly abstracted and automated visual process that helps companies rapidly build and continuously optimize mobile and web applications at scale. The Siemens low-code platform is designed to accelerate enterprise-class application delivery throughout the application development lifecycle from ideation to deployment and operation.
Create differentiation for your business
Standardized software is often used to solve a specific common problem, so there is a good chance that competitors in the industry are using similar solutions. In contrast, Siemens Low-Code is not designed to solve a specific problem, it is a unique low-code rapid application platform for development and delivery, enabling the entire application from ideation and development to deployment and operation Lifecycle provides a complete set of integrated tools. In an increasingly converging market environment, financial institutions can differentiate themselves by providing customers with low-code Siemens services.
Everyone can participate in application development
In the banking industry, especially smaller regional banks, are looking to maximize digital transformation on a limited budget. Since many banking institutions do not have IT DNA, but their development teams still need to face high-demand tasks such as automation, updating various applications, developing new applications, and replacing legacy systems, project rework and delays are even more common.
Siemens Low Code is unique in providing both no-code (visual modeling) and low-code (highly scalable, integrated tools to support collaborative work across functional teams) on a single platform. Through the platform’s collaborative and visual development capabilities, Siemens Low Code enables people across all functions to participate in the creation of applications that deliver sustainable business value. In other words, business and IT teams can collaborate on a single platform and focus on achieving the same goals, building applications together that solve real business problems.
Low-code lowers the threshold for development
In order to make it easy for enterprises to start their low-code development work, Siemens Low-Code continues to release new solution templates. These templates embody Siemens’ low-code experience in the financial industry for many years and help enterprises quickly get started with low-code development. These include:
• Customer Guidance: Turn the crucial initial user relationship building process into a relaxed and pleasant experience; • Native banking APP: uses biometric technology to achieve smarter user authentication, and provides chatbot function to provide users with 24/7 support; • Loan origination: Provide users with a convenient and fast loan application process, adding certain key parameters to automatically approve or reject the loan.
The above functions can be connected with the core system of the enterprise, and can be modified according to the actual workflow and brand tone to make it more personalized. With the support of these templates, enterprises can launch new functions in just a few weeks, respond quickly to new needs of users, and greatly improve customer experience. For more details, please click to watch the video.
Experience for a digital future
Undoubtedly, it is the pursuit of financial institutions to bring a better user and communication experience to users. However, if the traditional development method is used, limited by third-party technology and development costs, it may not be able to bring the ideal and beautiful experience to users; on the other hand, if the customized platform can quickly meet some of the needs of customers, it cannot Offer a more personalized service to differentiate.
If companies are still taking a wait-and-see attitude towards low-code development. Siemens Low-Code suggests that businesses can choose a small project as a touchstone to test low-code’s ability to quickly create solutions. This project doesn’t need to be perfect, it just needs to play a key role and demonstrate its key value in the development phase. Plus, IT teams can grab every link that can be filled and tested with low-code.
Mendix hopes that more and more financial institutions can accelerate the layout of the digital development blueprint through Siemens low-code, and stand at the forefront of digital transformation.
According to previous reports, Mercedes-Benz will release a new car at 9:00 on the 23rd. As scheduled, at 9 p.m. today, the new Mercedes-Benz C-Class was officially released. The new Mercedes-Benz C-Class, in addition to the exterior has undergone a major innovation, the interior has undergone earth-shaking changes, and is fully close to the new Mercedes-Benz S-Class. At the same time, the new car is equipped with the second-generation MBUX intelligent human-computer interaction system, which brings a more luxurious and technological experience in the form of a digital luxury cockpit.
Judging from the new C-Class official map, the new car’s air intake grille has not changed much, but the new car’s fog lamp grille has undergone a lot of innovation, using an oval shape, which looks very atmospheric. The shape of the headlights and taillights are also more slender, which strengthens the elegant and sporty characteristics of Mercedes-Benz, and the appearance is better. In the overall design of the appearance, the new C-class adopts the design language of the S-class. Previously, because the appearance of the new S-Class was too “impact” to car fans and friends, many car fans and friends directly called the ugliest “S-Class”. However, after the design language of the S-class was devolved to the C-class, the attitude of car fans and friends made a 180-degree turn, and praised the appearance and interior design of the new C-class. There are many highlights, which have indeed been praised by many people. It has to be said that Mercedes-Benz has profound experience in the aesthetic control ability of consumers. Compared with the appearance, the interior changes of the new Mercedes-Benz C-Class can be said to be earth-shaking. The new car has abandoned the dual-screen large screen of the current model, and instead adopts the central control inclined vertical screen design of the new S-Class. The air-conditioning outlet is Mercedes-Benz’s signature round shape. In the vehicle-machine system, the new car is also equipped with the second-generation MBUX intelligent human-computer interaction system of the new S-Class sedan, and the interactively upgraded “mind-reading voice assistant” can explain the functions of the vehicle.
In terms of power, the new C-Class brings a variety of options covering gasoline and diesel engines, 48-volt micro-hybrid and plug-in hybrid. The power is quite powerful. The gasoline version is equipped with the M254 four-cylinder engine and the second-generation 48V ISG intelligent motor, which can provide a maximum torque of 15kW and 200N m. Among them, the 1.5T engine has two power outputs, the maximum power is 125+15kW and 150+15kW respectively, and the peak torque is 250N m and 300N m respectively. The high power level reflects the excellent engine manufacturing skills of Mercedes-Benz. The world premiere of the new Mercedes-Benz C-Class sedan and C-Class wagon. As the first Mercedes-Benz car series to achieve full electrification drive, it is really sincere. The new C-Class brings a wealth of electrified power options covering gasoline and diesel engines, 48-volt micro-hybrid and plug-in hybrid. . The new C-Class with the fourth-generation plug-in hybrid technology will also be unveiled soon. We can look forward to it. It is equipped with a permanent magnet synchronous motor with a maximum power of 95 kW and a maximum torque of 440 Nm and a capacity of 25.4 With a kWh battery, the pure electric cruising range can reach about 100 kilometers (WLTP standard).
The model released this time uses a sports kit version, and the car will also provide an AMG Line version and a luxury version developed for the domestic market. The grille of the new car and the front surround show a trapezoidal shape. The headlights on both sides are also brand-new. The hook-shaped daytime running lights inside also highlight its youthful positioning. Such a design is definitely a departure from the previous Mercedes-Benz. Yes, this is very different from before. The interior of the car is basically a reduced version of the S-Class, and the 11.9-inch OLED touch screen comes into view, matching the second-generation MBUX in-vehicle system. Of course, if you buy a low-end version, the size of the screen will vary. The air conditioner button is added below, so it’s better to add money to the high-end equipment, are you excited?
In general, the new Mercedes-Benz C-Class has undergone a lot of improvement in terms of exterior and interior design, as well as overall product strength, and the effect is gratifying. And the whole car is also close to the Mercedes-Benz S-Class, a small “S-Class”. At present, the official guide price of the Mercedes-Benz C-Class currently on sale in China is 307,800-474,800 yuan, but the market terminal has a preferential space of nearly 35,000 yuan, which means that the price is quite favorable. The new Mercedes-Benz C-Class is expected to make its domestic debut at the 2021 Shanghai Auto Show, which will open in April. It will then be domestically produced by Beijing Benz and is expected to go on sale within the year. The price is expected to be similar to the current model. At that time, more than 300,000 yuan can buy a small “Mercedes-Benz S-Class”, will you be excited?
