Introduction to Digital Fluorescence Oscilloscope:
Digital fluorescence oscilloscope with a bandwidth of 1GHz, 4 channels, and a sampling rate of 5 GS/s per channel.

Detailed information of digital fluorescence oscilloscope:
The recording length, also known as storage depth, is one of the key indicators of a digital fluorescence oscilloscope. A digital fluorescence oscilloscope refers to the number of sample points that can be digitized and stored in one acquisition. The longer the recording length, the longer the time window that a digital fluorescence oscilloscope can capture with high resolution (high sampling rate). The world's first digital oscilloscope could only capture and store 500 samples, making it difficult to collect all relevant information for the investigated events. Over the years, oscilloscope manufacturers have offered increasingly longer recording lengths to meet the demand for long capture windows with high resolution. High resolution has either become a standard configuration for most mid-range oscilloscopes, or users can choose to upgrade to recording lengths of a few megabits. The recording length of these few megabits usually represents the signal activity of thousands of screens. Although the standard record length has significantly increased in recent years and can now meet the vast majority of application needs in the market, tools for economically and efficiently viewing, observing, and analyzing long record length collections have not received much attention until now. The DPO4000 series redefines engineers' expectations when dealing with long record lengths through the new control function of Wave Inspector.

1. Zoom/Scroll Display: The dedicated two-tier front panel knob allows for intuitive control of zoom and scroll display The internal knob adjusts the scaling factor (or scaling scale) by rotating clockwise to activate scaling and gradually increase the magnification factor; Turning counterclockwise can reduce the magnification factor and ultimately turn off the zoom function. The external knob scrolls the zoom box in the waveform, quickly obtaining the waveform part that the user is interested in The external knob also adopts a stress sensing design to determine the speed of the scrolling waveform. The faster the external knob rotates, the faster the zoom box scrolls. By rotating the knob in the opposite direction, the scrolling direction can be changed. You don't need to go through multiple menus to adjust the zoom view.
2. Play/Pause: When searching for abnormal events or events of interest, the dedicated play/pause button on the front panel automatically scrolls the waveform on the display screen. The playback speed and direction are controlled using intuitive scroll knobs. The faster the knob rotates, the faster the waveform scrolls. By rotating the knob in the opposite direction, the scrolling direction can be changed.
3. User tag: Did you see anything interesting on the waveform? Press the Set Mark button on the front panel to place one or more bookmarks on the waveform. To navigate between different markers, simply press the Previous and Next buttons on the front panel.
4. Search tag: Do you want to spend time examining the entire collected waveform and finding the event you are looking for? The DPO4000 series has a powerful waveform search function that can search for long-term collected data based on user-defined criteria. The search tag will highlight all events that have occurred and can be easily searched using the Previous and Next buttons on the front panel. The search types include edge, pulse width, short pulse, logic establishment time and hold time, rise/fall time, and I2C, SPI, and CAN packet content.

Establish and maintain time search function with high brightness to display various establishment and retention times that exceed the limit during a single acquisition.
The Wave Inspector control function provides unprecedented efficiency in viewing, navigating, and analyzing waveform data.
2、 Serial transmission and analysis
One of the most commonly used applications that requires long record lengths is serial data analysis in embedded system design. Embedded systems are ubiquitous. They may contain many different types of devices, such as microprocessors, microcontrollers, DSPs, RAM, EPROM, FPGA, A/D, D/A, and I/O. Traditionally, various devices have been using wide parallel buses to communicate with each other and with the external world. However, today, more and more embedded systems are replacing these wide parallel buses with serial buses because they require less circuit board space, fewer pins, lower power, and use embedded clocks and differential signals to improve noise resistance. Most importantly, their cost is lower. In addition, many well-known manufacturers are providing a large number of popular component components for rapid development and design. Despite the numerous advantages of serial buses, they also bring significant challenges that their predecessors (parallel buses) never faced. Debugging bus and system issues has become more difficult, isolating events of interest has become more challenging, and interpreting the content displayed on the oscilloscope screen has become more difficult. The DPO4000 series solves these problems and provides the best tools for engineers dealing with low-speed serial buses such as I2C, SPI, and CAN.
1. Bus display: It can combine and view various signals (clock, data, chip selection, etc.) that make up the bus at a higher level, making it easier to identify where data packets start and end, and identify sub packet components such as address, data, identifier, CRC, etc.
2. Serial triggering: On popular low-speed serial interfaces such as I2C, SPI, and CAN, data collection is triggered on packet contents such as packet start, specific address, and specific data content.
3. Bus decoding: Tired of having to visually inspect waveforms, calculate clocks, determine whether each bit is 1 or 0, combine multiple bits into bytes, and determine decimal values? Let the oscilloscope complete these tasks for you! Once the bus is set up, the oscilloscope will decode each data packet on the bus and display the values in the bus waveform in decimal or binary format.
4. Packet decoding table: In addition to viewing your own decoded packet data of the bus waveform, you can also view all captured packets in the table view, which is largely similar to the way data is viewed on a logic analyzer. It continuously lists data packets, including columns for each component (address, data, etc.).
5. Search: Serial triggering is particularly suitable for isolating events of interest, but once an event is captured and surrounding data needs to be analyzed, what should you do? In the past, users had to manually scroll through waveforms, calculate and convert bits to see what caused the event. With the DPO4000 series, you can have the oscilloscope search for collected data based on user-defined standards, including serial packet components. Display high brightness with search tags every time an event occurs. To quickly search between different tags, simply press the Previous and Next buttons on the front panel.
The packet decoding table displays the identifier for decoding each CAN packet in the long sampling set DLC、 Data and CRC

3、 What performance and feature set do you expect
The DPO4000 series digital fluorescence oscilloscope (DPO) provides the necessary performance for viewing the most demanding signals. With a bandwidth range of 350 MHz-1GHz, and all models offering at least 5 times oversampling rate on all channels and standard sin (x)/x interpolation, you can confidently capture and display the fastest instantaneous events accurately. All channels are labeled with a recording length of 10M, which can capture long signal activity windows while maintaining fine timing resolution.
The DPO4000 series digital fluorescence oscilloscope provides various analysis solutions, including cursor, 25 automatic measurement functions, statistics, and waveform mathematical operations. Despite its small size and light weight, the DPO4000 series still offers outstanding performance, a 10.4-inch large XGA display, and vertical control function for each channel knob. The new TekVPITM probe interface establishes a standard for ease of use in detection. The TekVPI probe has status indicator lights and control functions, and a probe menu button in the compensation box. This button can launch a probe menu on the oscilloscope display, which includes all relevant settings and control functions for the probe. The TekVPI interface adopts a new probe power management structure, which can directly connect current probes without requiring a separate bulky power supply. Finally, TekVPI probes can be remotely controlled through USB, GPIB, or Ethernet, providing a more versatile solution in ATE environments. The DPO4000 series offers new USB plug and play operation and PC connectivity capabilities. To collect data and measure from the instrument, simply connect a USB cable from the oscilloscope to the PC. The applications provided include National Instruments

4、 Other applications of digital fluorescence oscilloscope
Video design and development: Many video engineers have always had a special fondness for analog oscilloscopes, believing that the grayscale levels on analog displays are the only way to view specific video waveform details. The fast waveform capture rate of the DPO4000 series, coupled with signal grayscale maps, provides the same information as analog oscilloscopes, but with a much higher level of detail, while also offering all the benefits of digital oscilloscopes. Due to its bandwidth of up to 1 GHz and four inputs, the DPO4000 series provides ample performance for both analog and digital video.
Digital Circuit Design and Debugging
The iViewTM function of Tektronix enables interoperability between the DPO4000 series oscilloscope and Tektronix TLA5000 series logic analyzer, enabling circuit designers to meet signal integrity challenges and debug and verify systems more quickly, conveniently, and effectively. The iView function fully integrates the industry-leading performance and measurement accuracy of Tektronix oscilloscopes with the multi-channel and powerful triggering functions of Tektronix logic analyzers. This integration capability enables designers to view time related digital and analog data in the same display window, isolating the analog characteristics of digital signals that cause problems in the system. The iView Wizard function guides users through the setup and connection process, simplifying the integration of oscilloscopes and logic analyzers. It does not require any user calibration. In addition, once set up, the iView function is completely automatic. As a result, it provides a comprehensive tool for digital design and debugging.
