getspeed posted a topic in Identificação e Equivalência de Componentes
What is a dongle? A dongle is a compact device that attaches to a computer or other electronic equipment to enhance functionality or provide security. Typically, it operates as a plug-and-play accessory, connecting through a universal serial bus (USB) port. How does a dongle work? When you plug a dongle into a universal serial bus (USB) port on your computer, it establishes a connection and communicates with the software or hardware it is designed to work with. The dongle acts as an interface between the computer and the device or software, allowing them to interact and exchange data. What are some common uses of dongles? Dongles serve a variety of purposes across multiple domains. One common application is in hardware protection, such as software license dongles, which are used to prevent unauthorized software usage. For instance, a software license dongle ensures that only licensed users can access specific software by requiring the physical presence of the dongle. Dongles are also utilized to provide wireless connectivity; for example, WiFi dongles enable devices without built-in WiFi to connect to the internet. Beyond these uses, dongles can function as data storage devices, facilitate audio or video transmission, or act as adapters to connect devices with different types of connectors. What is an example of a software dongle? Imagine you have purchased a specialized graphic design software program. To safeguard their intellectual property and prevent unauthorized usage, the software company might include a dongle that must be connected to your computer whenever you use the software. This dongle acts as a security measure—without it, the software will not operate correctly, ensuring that only those who possess the dongle, and therefore a valid license, can use the program. What are the advantages of using dongles? Dongles offer several significant advantages. Firstly, they enhance security for both software and hardware by necessitating physical presence for access, which helps to prevent unauthorized copying or use of protected content. Secondly, their portability is a major benefit; being compact, dongles can be easily transported and used across different devices.

USB Type-C, also known as USB-C, is a universal serial bus (USB) hardware interface form. the largest in appearance is that the upper and lower ends are completely consistent, and the USB is no longer distinguished compared to Micro-USB. The USB Type-C specification 1.0 was published by the USB Developer Forum (USB-IF) and completed in August 2014. It is basically the same as the USB 3.1 specification. But USB-C is just a port that doesn't necessarily support USB 3.x or power transfer (many phone types -C still use USB 2.0). Since the release of the USB-C specification in 2014, many new Android mobile devices, laptops, desktops and even 3C devices, such as game consoles, please start using this connection port. Windows 10 itself supports USB Type C. The USB-C port is 8.3× 2.5mm in size, which is smaller than the current USB port on PCs, but slightly larger than the 6.85× 1.8mm microUSB port, which is 6.85× 1.8mm in size. As for the power transmission specification, the wire standard is 5V, 5A, and the connector is 3A. The additional design of the device required Type-C due to incompatibility with any existing Type. The world's first source of USB 3.1 main control terminals and device terminals was presented by ASMedia at the Annual Conference in 2014. In an interview, Brad Saunders, chairman of the USB 3.0 Enablers Group, said, "While USB technology is the most popular for connecting devices and charging devices, we still recognize that we need to develop a new joint to meet the evolving trend. For example, progression size and availability. The new USB-C connector will meet the needs of the market and lay the foundation for future USB versions. " USB-C is designed as the ultimate universal connection. Its size allows it to be used on computers and mobile devices. The design also allows you to use not only the USB 3.1 protocol but also Thunderbolt 3 and DisplayPort. This means that you can do all the content of USB-C via USB-A and USB-B, but you can also connect powerful peripherals (such as GPUs) and display them on USB-C ports. USB Type-C is still quite new and has not yet been incorporated into most of the devices we use on a daily basis. Right now, you'll only find USB Type-C in Apple MacBook computers, some Chromebooks and other newer laptop models, and some flash drives. It is also used on the Nintendo Switch game console.

 devolvido What Types of Video Wall Processors Can I Choose?
vissonic posted a topic in Home Appliances
When considering investing in a 4K video wall, there are some important factors you need to keep in mind. In this guide, we'll take a look at what a video wall is, some of the technology behind it, and the four types of video walls used for different applications ranging from basic to complex. What is a video wall? A video wall is a type of multi-display wall that displays a larger image or windows of multiple images by connecting multiple screens together. The display technology can be LCD or LED panels, tiles, cubes or projection screens. A video wall can be as simple as one image from a single source stretched across multiple screens. These types of video walls offer greater flexibility, control, scalability and creativity. Display Screens When planning your video wall, consider what type of display you want to use. You can choose from LED and LCD panels, tiles, cubes and projector systems. Not all displays have the same brightness or resolution, and these specifications are likely to be important decision criteria. The more detail and clarity you require, the higher the resolution you'll need. You also need to consider the width of the monitor's bezel. Newer monitors have ultra-narrow bezels, resulting in a perfect image. Video Wall Processors Today, the terms video wall processor and video wall controller are often used interchangeably. Their basic job is to split the video content for each display in a multi-display wall. A video wall processor is a video scaler that ensures that each source signal goes to the correct screen at the correct resolution. It acquires the image and sends it to each screen to be displayed as one large, cohesive image. The video processor is responsible for taking the various inputs and putting them together. An advanced video wall processor can take content from multiple sources and display it on multiple screens. A video wall processor is similar to a traditional video scaler, but with greater input, output and processing power. Modular Seamless Switching Videowall Processor 8x8 Video Scalers Sometimes, video wall processors can be located close to the display and can be connected directly via video cable. In other applications, video wall processors may need to be located in server rooms or IT rooms that are too far away to use standard video cables. In these cases, a video extender is required to transmit the video signal from the video wall processor to the display. For cable distances as short as 30 feet, a video extender may be required. Some IP-based systems use small receivers (one per monitor) that can be mounted on the back of the monitor. In these cases, signal extension is done over the LAN and no additional video extension is required. Advanced Video Walls Advanced video walls are screens that support a large number of different form factors (e.g., 3x2, 3x4, 6x4, etc.) and provide a canvas-style user and display interface on which many content windows can be dynamically moved or adjusted. Advanced video wall processors typically support dozens of screens and many types of video inputs. These types of video wall processors can also support local decoding of IP streams to display a large number of streams from devices such as IP-based security cameras or other remote sources. Some are also capable of encoding video sources to be shared with other sites or users. Advanced video walls are found in mission-critical control rooms that need to be up and running 24/7. When considering which type of video wall fits your unique needs, you first need to consider how you intend to use the video wall. Do you want a simple digital signage type display, a large state-of-the-art control room wall or something in between? What environment will the video wall be used in: military/tactical, security, utilities, retail, education, transportation, museums, industrial, conference rooms, etc. -
 devolvido What is a power divider
Hansen Hou posted a topic in Identificação e Equivalência de Componentes
A power divider is a device that divides the energy of an input signal into two or multiple outputs of equal or unequal energy, and can also combine the energy of multiple signals into one output in reverse, which can also be called a combination. router. A certain degree of isolation should be guaranteed between the output ports of a power divider. Power divider is also called overcurrent divider. It is divided into active and passive. It can evenly distribute one signal into several outputs. Generally, each branch has a few dB attenuation. The signal frequency is different, and the attenuation of the divider is also different. Different, in order to compensate for the attenuation, a passive power divider is made after adding an amplifier. The technical indicators of the power divider include frequency range, withstand power, distribution loss from main circuit to branch, insertion loss between input and output, isolation between branch ports, voltage standing wave ratio of each port, etc. 1. Frequency range. This is the working premise of various RF/microwave circuits, and the design structure of the Xinqiyuan power divider is closely related to the operating frequency. The operating frequency of the distributor must first be clarified before the following design can be carried out 2. Withstand power. In high-power Splitters, the maximum power that circuit elements can withstand is the core indicator, which determines what form of transmission line can be used to achieve the design task. Generally, the order of transmission line power from small to large is microstrip line, stripline, coaxial line, air stripline, and air coaxial line. Which line to use should be selected according to the design task. 3. Distribution loss. The distribution loss from the main circuit to the branch circuit is substantially related to the power distribution ratio of the power divider. For example, the distribution loss of the two-half power divider is 3dB, and the distribution loss of the four-half power divider is 6dB. 4. Insertion loss. The insertion loss between the input and output is due to factors such as the imperfect medium or conductor of the transmission line (such as a microstrip line), and the loss caused by the standing wave ratio at the input end is considered. 5. Isolation. The isolation between branch ports is another important indicator of the power Combiners. If the input power from each branch port can only be output from the main circuit port, and should not be output from other branches, this requires sufficient isolation between the branches. 6. Standing wave ratio. The smaller the VSWR of each port, the better. As a professional power divider manufacturer, Xinqiyuan is a technical innovation enterprise specializing in the manufacturing of RF microwave test devices such as RF power divider, RF coaxial cable components, precision RF connectors, precision RF loads etc.-
