SyntheSys Offers BERTScope with Jitter Analysis Covering 80 MHz

SyntheSys Research introduced a new BERTScope Digital Communications Receiver with Jitter Analysis (DCRj) for telecom applications and developers of XFP and SFP+ transceivers.



The DCRj, which is capable of showing the full 80 MHz spectrum, is a standalone jitter measurement solution with built-in compliant clock recovery that also provides OC-192/STM-64 and 10GbE reference receiver capability to the BERTScope series of analyzers and third-party instruments used for transmitter compliance.



The DCRj has an amplified receiver for testing single-mode or multimode transmitters. The DCRj also provides an electrical input to enable jitter spectral analysis on electrical signals.



SyntheSys said that while the majority of the optical or electrical signal is passed through to provide an electrical output for other test instrumentation, a small portion is used to drive a standards-compliant, flexible clock recovery. As well as providing the correct loop bandwidths for transmitter measurements, such as the 4 MHz loop bandwidth called for by SONET, the DCRj also provides the engine for one of the most sensitive jitter generation measurements available. The benefit is that test devices may be checked for compliance to standards, and the same measurements can be used for performance enhancement and troubleshooting efforts through the >80 MHz jitter spectrum measurement.
