SDS3000X HD High Definition Digital Oscilloscope

When a high-speed ADC performs data acquisition, the signal-to-noise-to-distortion ratio of the actual ADC falls short of the desired performance that its nominal bits should achieve due to noise and distortion. In general, the higher the oscilloscope bandwidth, the higher its internal noise. This is because high-frequency noise enters the high-bandwidth oscilloscope. Since the ADC is only a part of the oscilloscope system and cannot be used independently, the ENOB index of the whole oscilloscope system will be more meaningful.SDS3000X HD is up to 8.3-8.6-bit, with smaller time error and frequency spuriousness, as well as lower broadband noise, which can effectively ensure the accuracy of measurement.

SDS3000X HD series oscilloscopes provide a wealth of trigger types, including edge, interval, timeout, video, serial bus, area trigger, etc. Among them, area trigger is different from the traditional trigger, which can be applied to episodic signals whose parameter characteristics are still unclear, and the signal capture can be completed by creating and defining an area using only the mouse or touch. Bus trigger supports I2C, SPI, CAN, CAN FD, FlexRay, I2S, MIL-STD-1553B, SENT and other buses, providing test solutions for embedded, automotive, computer and other serial buses.

The template test function is mainly used for signal quality assessment, which can monitor the failure rate of waveforms for a long time and locate the causes according to the faulty waveforms. There are two ways to set rules, one is to create rules by drawing polygonal templates in the oscilloscope, the other is to create rules by setting horizontal and vertical values according to the "Perfect Waveform", and then the oscilloscope conducts real-time testing of the waveforms, and it can count the number of times of testing, number of times of failures, and failure rate within the specified testing conditions, and it can also set the "Store Failure Frames", and the failed waveforms can be viewed in history mode. It is also possible to set "Store Failure Frames", and the failed waveforms can be viewed in history mode.

SDS3000X HD can be equipped with optional power supply analysis function, together with Dingyang's voltage probes (e.g. DPB5000 series) and current probes (CP6000 series), it can quickly and accurately analyze 12 parameters of power supply such as power quality, current harmonics, inrush current, transient response, safe operating area (SOA) of the MSO tube, etc., for example, to improve the efficiency of the power supply by minimizing switching loss, assess device operating stability by Statistical power devices in all working conditions transient parameters exceed the probability of safe operating area to assess the device operating stability, through the input current harmonic analysis, to observe whether there are abnormal harmonics affecting power quality, etc., can improve the efficiency of power supply developers.
