Lianxun PAM4 Oscilloscope Helps Optical Communication
The development and production of optical communication networks and high-speed interface optical chips, optical devices, and optical transceiver modules all require high-performance sampling oscilloscopes for accurate measurement and verification. In order to ensure that the eye diagram of the high-speed optical signal under test can be tested accurately, the oscilloscope usually needs to have higher bandwidth, lower amplitude noise and lower inherent jitter. Based on the principle of isochronous sampling, the sampling oscilloscope does not require expensive and complex ultra-high sampling rate ADCs, but can use ADCs with higher conversion bits, so it overcomes the shortcomings of high cost and poor accuracy, and is more suitable for ultra-high-speed optical/electrical interface testing , and has been widely recognized as a standard conformance test instrument by various standard specifications. For a long time, sampling oscilloscopes have been monopolized by foreign test instrument giants. China, the global optical communication industry gathering place with the largest demand, has not had independent and controllable related test products for decades.
Is basically an oscilloscope adapted for high speed optical photonics, they even compared it with "Keysight", it use an complex algorithm to avoid using highly complex analog to digital converters that would make this more costly for its intended purpose, but there is nothing stopping this guy from making versions for general purporse analog sampling like high speed gallium nitride RF ICs, who knows.
