The latest advances in oscilloscope connectivity
As with most technologies, oscilloscopes are also keeping pace with the times. In the past, only expensive “top-level†oscilloscopes were available, and now they have become popular in low-cost oscilloscopes. These features include scalable bandwidth, memory depth, large display and high-speed waveform capture rates, and more. In the past, high-end oscilloscopes were equipped with Ethernet, USB, GPIB, VGA, trigger input, and trigger output connections. Economical oscilloscopes often did not have all connections. Some oscilloscopes used floppy disk drives or only GPIB interfaces.
Fortunately new connectivity options have begun to spread to cheaper oscilloscopes. What are the new options for non-Windows oscilloscopes?
USB Connectivity In almost all cases, the oscilloscope has replaced the floppy disk drive with USB. When the user wants to save screenshots or data files, just insert a USB flash drive to save screenshots and data? ? . This is often referred to as "USB host side." As you might expect, USB offers technical advantages over previous data saving options, including greater storage space (up to 128GB for Agilent 2000 and 3000X series), smaller form factor and easier transfer to your PC ( Remember the last time you used the floppy disk drive?).
The connection via the USB host is often referred to as an "intermediary", although you can easily use a USB stick to transfer files to the oscilloscope or from an oscilloscope, but this is not really a direct connection. You must also use USB flash drives to transfer information between the computer and the oscilloscope.
In addition to the USB host, many oscilloscopes now have a USB device connection. It is not used to connect a USB stick, but instead allows you to control the oscilloscope from a remote location via USB. To enable this connection, connect the USB host on the PC with the USB device on the oscilloscope through the USB cable.
USB device-side connections usually involve a certain kind of driver library. Agilent uses its IO library, which includes programs that help you set up oscilloscope links. Once the connection is established, you can use commands to control the oscilloscope.
Ethernet Connectivity Although USB connectivity is common today, Ethernet connectivity is a fairly new technology, especially for less expensive non-Windows oscilloscopes. Now you have the ability to control the oscilloscope remotely on an Ethernet network, and even print oscilloscope measurements on a network printer. Ethernet connectivity not only provides another way of connecting oscilloscopes, but the new Ethernet connection called LXI (an extension of the LAN in the field of instrumentation) provides a completely new way of interacting with test equipment. Not only does LXI easily configure your test system, it integrates with other instruments through a variety of connectivity options, including traditional standards such as GPIB, but it also has many unique capabilities that make oscilloscopes very interactive. For example, an Agilent LXI instrument has a Web server embedded in it. This embedded webpage has many outstanding advantages:
* Identify oscilloscope information such as model number, serial number, host name, IP address, and VISA (address) connection string * Remotely control the oscilloscope through the virtual front panel on the PC * Send SCPI through the SCPI command window (standard command for programmable instruments) Command Capabilities * Ability to save settings on the PC, waveform data (multiple formats) and template files * Ability to call settings, waveform data files, and template files from a PC * Capture screen images and easily add images to documents The ability to flash the 'active' information on the oscilloscope being controlled - this is especially useful when you control one of several oscilloscopes in the cabinet because you don't need to do any special action , you know which oscilloscope is currently controlled.
* Ability to upgrade firmware over the network LXI instruments provide the ability to remotely control via a virtual front panel. The virtual front panel reproduces all functions of the oscilloscope. Some oscilloscopes, such as the Agilent InfiniiVision X-Series oscilloscopes, offer you two types of virtual front panel options:
1. Basic Virtual Front Panel 2. Virtual Front Panel that is exactly the same as a physical oscilloscope The basic virtual front panel is usually a simplified view of the oscilloscope's applicable functions. This is the ideal remote control for PCs that have limited screen resolution, so the interaction with the oscilloscope is compressed to a very limited range. It is also more suitable for the mouse, rather than the touch-driven finger.
The Agilent InfiniiVision X-Series oscilloscopes have another option, which is the same virtual front panel as the real oscilloscope front panel. This virtual front panel has the same functionality as the oscilloscope front panel, which is the most obvious use and benefits. It is ideal for people who may use the oscilloscope remotely because they have the same appearance and operation as if they were directly manipulating the oscilloscope. If you are using a touch screen PC, you can easily use your finger and mouse for remote control on this front panel.
In addition to the similar appearance and operation of the remote interface and the front panel of the oscilloscope is a great advantage, another major advantage of this remote oscilloscope front panel is training and education. When you set up a new production line or lab, and if not everyone can be assigned to an oscilloscope at any time, you can connect an InfiniiVision oscilloscope to your company's internal network so anyone can enter the oscilloscope IP address and practice using it. , so that when the oscilloscope gets in front of itself, it is already familiar with its operation. It is also a powerful teaching tool. With this function, teachers in the laboratory can interact with an oscilloscope through their virtual front panel. Students can see the operation of the oscilloscope, observe the teacher interacting with it, and capture the screen. Save data and other operations. Although many people can't perform different actions at the same time, it is very useful for many students to use the oscilloscope on time or at the same time for a laboratory with limited equipment.
The other advantage of the virtual front panel and the actual front panel of the oscilloscope is that engineers can reconcile problems between multiple teams in different locations. The team engineers and you directly see exactly the same front panel and signal waveforms, so you can solve the concerns of everyone through direct communication.
Conclusion of this article If you are still using an oscilloscope with a floppy disk drive, or even a USB-only oscilloscope, you may be surprised at these new connectivity technologies, especially their extremely low price points. With the oscilloscope's replacement, they are becoming more and more powerful, flexible and easy to use. The new features of the oscilloscope, such as Ethernet connectivity, will greatly increase your productivity if combined with Web server functionality.

What is green? When we entered the forest, it was as if we had jumped into a green ocean and were immediately engulfed by it. Green is the color of life, the forest is as green as jade, the valleys are covered with green velvet, the river is like flowing grease, and the moist air gives a crystal like feeling. Green, also known as the color of eye protection, when you are tired of watching TV, computer, or using your eyes, go out and look at the green lawn, green plants, or you can also keep some green plants at home. Will your eyes feel particularly comfortable? Put a pot of green plants next to your desk, and children who have been reading and studying for too long can shift their attention to green. Due to the unique characteristics of green, we have used it as the color for the Ebike Frame of Electric Bicycles. Imagine children riding a green Electric Bicycle home after a busy day of learning, which not only gives their eyes a good rest but also exercises their body, achieving two goals with one stroke. At present, our LC02 and Mini models have green options, which you can choose according to your children's preferences.
