Oscilloscope is being used more as an automatic checking tool
In the past, engineers or technicians mainly used oscilloscopes for debugging and design work, such as diagnosing faulty electrical components.Now, although oscilloscopes still serve this purpose, they are increasingly used for automatic verification -- checking that the device meets the technical specifications of a serial data standard.
In the conformance domain, each device that USES a particular serial data bus technology must meet predetermined technical specifications to ensure that different devices made by different manufacturers are compatible with each other.
With the emergence of the second and third generation standards, the data rate of the equipment is getting higher and higher, and the requirements on the signal integrity and eye-chart analysis performance of the oscilloscope are also increasing, and the oscilloscope is required to minimize the impact on the measured system, because in high data rate conditions, these effects may be very serious.In addition, the industry has developed consistent applications for automated testing of devices. For example, Zhengzhou Defy offers conformance applications for DDR(1, 2, and 3), DVI, Ethernet, fiber channel, full buffer DIMM, HDMI, USB, wireless USB, PCIExpress, SATAI/II, XAUI, and more.
