Keysight Digital Communication Analyzer (DCA) Solutions For more than 25 years, Keysight has been the leader in the sampling scope industry. We’ve designed Digital Communications Analyzer (DCA) solutions to increase the efficiency and accuracy of test. Along the way, we’ve proudly created industry-leading sampling scopes, modules, accessories and software used to test communications infrastructure from the serial I/O semiconductors to optical transceivers in modern data centers. We innovate so you stay on the leading edge.

Engineered for Unmatched Measurement Accuracy As the market demands faster and more data, you respond by designing high-speed digital communications infrastructure components that perform nearly error-free and accommodate signals with shorter bit periods and faster edge speeds. You employ techniques such as emphasis and equalization and take great care to minimize jitter and noise impairments on signals. Built to test communications infrastructure, our DCA solution family provides industry-leading measurement accuracy for high-speed digital designs such as 800G/1.6T Ethernet and 128G Fibre Channel,...

What Does a DCA Measure? A Digital Communications Analyzer (DCA) is Keysight’s term for instruments otherwise known as sampling oscilloscopes or equivalent-time sampling oscilloscopes. Due to its superior accuracy, dedicated analysis features, and lower cost than other oscilloscope technologies, the DCA is the ideal instruments used to view the time-domain waveforms of optical and electrical transmitters used in highspeed serial communications systems. • Wide bandwidth in excess of 100 GHz • Low noise and low jitter • High vertical resolution, up to 16 bits • 30 GHz configurations starting at...

How Do DCA Sampling Scopes Compare to Real-Time Scopes? Today’s high-end electronics deliver signaling speeds from at least a few Gbaud to over 100 Gbaud. The physical properties of semiconductors and other materials can make it very hard to design a product that works at the desired low bit or symbol error ratio (BER, SER). While a BER or SER tester measures the overall digital performance of a channel or link, oscilloscopes provide insight into the signal properties of a transmitter and consequently allow engineers to identify parts of the design which need further improvement. Practically...
