Keysight unveils 60 GHz optical-to-electrical converter for high-speed oscilloscope tests

Aug. 10, 2020
Keysight expands optical front-end solutions for its Infiniium real-time oscilloscope.

Keysight Technologies, Inc. (NYSE: KEYS) recently announced its new N7005A optical-to-electrical converter, designed for use with the company's Infiniium UXR-series of high performance real-time oscilloscopes. The N7005A provides real-time analysis and debugging capabilities on up to 4 channels simultaneously, offering designers new testing methodologies.

As noted by Keysight Technologies, "As demand for IoT-based applications, HD streaming, cloud services and 5G continues to increase, the need for higher data throughput communication and more efficient test solutions in the optical domain steadily grows as well. 400G with PAM4 signaling is more complicated than 100G with non-return-to-zero (NRZ) modulation and significantly increases the required time for design validation, debug and troubleshooting cycles."

Keysight says its real-time, oscilloscope-based optical measurement tools offer unique capabilities that address such measurement challenges, while also debugging and troubleshooting optical product designs, typically in the R&D design phase.

Keysight’s N7005A, which offers up to 60 GHz of optical measurement performance (O/E), used in conjunction with the company’s 70 GHz Infiniium UXR oscilloscope, offers designers end-to-end debugging capabilities that reduce time needed to debug, while simplifying overall workflow results. It also enables engineers to take advantage of the PAM4 optical measurement and deep analysis capabilities such as TDECQ [transmitter and dispersion eye closure quaternary] measurement provided by the new FlexDCA sampling oscilloscope software feature called FlexRT.

Keysight’s N7005A delivers a low-level of noise for 56-GBaud optical PAM4 measurements, enabling engineers to efficiently troubleshoot optical devices using a complete set of debug capabilities. Each N7005A O/E converter contains a measured frequency response data for an optimized correction filter. This frequency response data is used to flatten the frequency response for a more accurate measurement.

“Keysight’s new N7005A delivers a high-bandwidth optical input solution for the Infiniium UXR oscilloscope with ultra-low noise for high signal integrity optical measurements,” commented Brad Doerr, vice president and general manager of Keysight’s Digital and Photonics Center of Excellence. “This is an important addition to Keysight’s portfolio of optical measurement solutions based on real-time and sampling oscilloscope platforms and it will enable key capabilities for test/debug of emerging 400G/PAM4 signaling standards.”

Keysight'a N7005A optical-to-electrical converter is available now at USD $70,000. Additional information is available at www.keysight.com/find/n7005a.
