Shulou(Shulou.com)11/24 Report--

Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com January 3 news, Dingyang Technology held a new product conference on December 28, releasing 4GHz bandwidth, 12-bit high-resolution digital oscilloscope SDS7000A and 8GHz self-developed oscilloscope front-end amplifier chip SFA8001. Among them, SDS7000A is the first domestic 4GHz bandwidth, 12-bit high-resolution digital oscilloscope, which promotes the domestic high-resolution oscilloscope to a new height and fills the domestic blank in related fields, while SFA8001 is the first self-developed oscilloscope front-end amplifier chip whose bandwidth reaches 8GHz.

CTOnews.com learned that the SDS7000A series, as a new flagship oscilloscope product of Dingyang Technology, uses a brand new 15.6in HD touch screen on the basis of 4 GHz bandwidth and 12-bit high resolution, which is a real "HD" oscilloscope. SDS7000A supports split-screen display function, and the waveform is clear and reliable from the whole to the details.

SDS7000A also realizes the overall upgrade of the processor, from embedded ARM processor to X86 processor, which greatly improves the system response speed, measurement, operation and analysis speed, and leaves more possibilities for the expansion of software analysis function in the future.

The maximum bandwidth of SDS7000A oscilloscope is increased to 4GHz, and the rise time is only 100ps, which is more than double that of 2GHz oscilloscope. It can support the measurement of USB2.0, SATA1, DDR1/2/3 and other signals, and the application scenarios are more abundant. SDS7000A uses 12-bit high-resolution design, quantization series up to 4096, 16 times that of the traditional 8-bit oscilloscope, which can help engineers to observe the details of the waveform more completely and clearly, and carry out more accurate waveform measurement.

The sampling rate of SDS7000A series oscilloscope is up to 20 GSa / s, which is 5 times of the highest bandwidth, which can perfectly avoid signal distortion caused by insufficient sampling rate. With a long storage depth of up to 1 Gpts / channel, the waveform can be captured for a long time, while still capturing the waveform with higher sampling rate and high fidelity, giving full play to the performance of 4GHz bandwidth.

The three core chips in the digital oscilloscope are: front-end amplifier chip, ADC chip and digital signal processing chip. These three kinds of chips perform their own functions, and all have a direct impact on the performance of the oscilloscope. As the core of the front-end analog circuit, the amplifier chip limits the analog signal processing ability of the oscilloscope. it can realize the impedance transformation, bias control and other functions of the analog signal, and even directly determines the most important parameter of the oscilloscope: bandwidth.

As the first special chip for the front-end amplifier of Dingyang Technology, SFA8001 has the high bandwidth of 8GHz and the low noise density of 1.9nV/ √ Hz, which can help oscilloscopes observe signals with faster speed and smaller amplitude, and lays a solid foundation for the research and development of Dingyang 8GHz and subsequent higher bandwidth oscilloscopes.

Dingyang Technology said that as early as the research and development of 4GHz oscilloscopes, the company has planned the strategic layout of chip self-research. Based on the technical accumulation in the analog front-end circuit of the oscilloscope in the past ten years, we actively set up a chip research and development team, and finally realized the breakthrough of self-research chip from "0" to "1". It not only solves the problem of strategic development of high-end oscilloscope products, but also accumulates valuable technical experience in the future development of 16 GHz amplifier, and the company's core competitiveness has also been further improved. The high-end oscilloscope with the 8 GHz chip will be available in the near future, the company said.
