For any high-speed communication signal, the channels and basic signal characteristics must be tested to ensure that they meet standards and are interoperable with other devices in the system plan. Digital communication analyzer (DCA) based on widebａnd sampling oscilloscope has a long reputation in the field of R&D, device validation and batch transceiver production, and is recognized as the industry standard for accurate analysis of optical waveforms. In addition to the basic eye map and pulse waveform characterization, the digital Communication analyzer (DCA) oscilloscope can perform advanced dither analysis and channel impedance characterization.

Transmitter conformance test and eye map analysis
Eye-view is the most common way to characterize the signal quality of high-speed digital transmitters. Industry standards such as SONET, SDH, Fibre Channel, and Ethernet rely on eye map analysis to determine transmitter technical specifications. By looking at the eye map, you can determine the template margin, amplitude, extinction ratio, and overall quality. Testing typically uses a well-defined reference receiver to capture conformance test results in production testing, input validation, and system-level applications. Digital Communication Analyzer (DCA) oscilloscope has a built-in standard reference receiver and test program for consistency testing.
