ZDS2024: A more comprehensive oscilloscope for engineers

　　With the development of technology, engineers have more and more requirements for oscilloscope functions and higher performance during the test process. ZDS2024 innovatively adopts DDR3 storage technology and cooperates with large-scale FPGA devices to make the oscilloscope more powerful.

　　With 250M storage depth

　　If the storage depth can be large enough, the highest waveform sampling rate can be maintained, and the observed waveform will be more realistic and delicate. On the contrary, if the storage depth is only 1Mpts or even lower, when observing a waveform with a longer duration, the oscilloscope will be forced to reduce the sampling rate. Due to insufficient sampling points, the waveform displayed by the oscilloscope will also be severely distorted, and even waveform aliasing will occur, misleading the user's measurement and analysis. ZDS2024 uses full hardware acceleration and multi-threaded parallel processing, with a storage depth of up to 250M, and waveform details will not be lost when observing long-term waveforms.

　　25 protocols decoding

　　When debugging protocol signals, engineers not only need to observe the protocol waveform, but also decode the waveform into corresponding data. However, the protocol decoding function of oscilloscopes of major brands has always been a paid option, and there are only a few types. The ZDS2024 Plus oscilloscope is equipped with 25 protocol decoding for free, including CAN, LIN, I2C, SPI, UART, USB, PS/2, DALI, Wiegand, 1-Wire, DS18B20, HDQ, SD_SPI, SD_SD, IrDA, Manchester, DiffManche, Miller, DHT11, SHT11, NEC, RC5, RC6, FlexRay. In addition, the ZDS2024 Plus is exclusively equipped with CAN FD protocol decoding, pushing the 200M oscilloscope to the top.

　　330,000 times/second waveform refresh rate

　　Due to the technical limitations of the real-time processing capability of the waveform synthesizer and the throughput bandwidth of the waveform display memory, the waveform refresh rate of the 2000 series oscilloscope is generally very low, and there is a lot of dead time in waveform observation. Engineers will miss many waveform details, which greatly reduces work efficiency. The ZDS2024 oscilloscope uses a large-scale FPGA, from the initial 75K to 150K, 260K to the final 330K. The higher waveform refresh rate can quickly detect abnormal signals and significantly improve work efficiency. [page]

　　Template trigger

　　When debugging products, engineers often encounter some signals that are difficult to capture. Without understanding the characteristics of the signal, can they be captured in a simple and easy-to-use method? ZDS2024 innovatively adds a template trigger function based on the powerful trigger function of the oscilloscope. Through the touch filtering principle, it realizes the function of isolating any regular abnormal signal.

　　4Mpts FFT Analysis

　　Currently, most 2000 series oscilloscopes only support FFT analysis with a maximum of 8K sample points. At a sampling rate of 1G, the frequency resolution is only 125KHz, and in most cases, it is impossible to accurately determine the signal spectrum distribution. The ZDS2024 oscilloscope uses a professional processing chip to upgrade the FFT analysis points to 4M sample points. At a sampling rate of 1G, the frequency resolution can be as accurate as 250Hz, which can accurately analyze the source of interference noise in the circuit, greatly improving the practical value of the oscilloscope FFT.

　　Supports automatic measurement of 51 parameters

　　It is far from enough to analyze the waveform only through its intuitive performance. Only by accurately quantifying the various indicators of the waveform can we see through the essence of the waveform anomaly. However, due to the limitations of the architecture and chip, the parameter measurements of most oscilloscopes are based on sampling results. No matter how many signal cycles there are on the screen, only one cycle signal in each screen is extracted for statistical measurement, which directly leads to serious distortion of the results. ZDS2024 uses FPGA for full hardware acceleration. By measuring each cycle signal on the screen, it calculates the maximum value, minimum value, average value, standard deviation of each indicator, and there are as many as 51 types. [page]

　　Waveform search function

　　When debugging the signal waveform, it is necessary to clarify whether the signal is abnormal. If there is an abnormality, how often do these abnormal signals appear, and do they appear periodically? In order to figure out these problems, it is generally necessary to record the waveform for a long time, and then locate the position of the abnormal waveform based on such a huge waveform database. Relying on the advantages of massive storage and hardware acceleration, ZDS2024 can quickly locate the signal of interest from hundreds of thousands of waveforms. As long as a waveform signal that meets the search conditions appears on the current screen, the system will automatically mark the corresponding position, and the abnormal signal will be clearly visible.

　　Seven one-button operations

　　In October 2012, the third oscilloscope was successfully developed. During the trial, users found that it was very cumbersome to store waveforms in a USB flash drive. The ZDS2024 oscilloscope combines 80% of the functions used by 80% of users, 80% of the time, into seven one-key operations. The functions are coherent, easy to distinguish, and one-key operation significantly improves test efficiency.
