Tektronix has launched the DPO7OE1, a calibrated optical probe and analysis software for use with real-time oscilloscopes. It is optical reference receiver (ORR)-compliant for 28-GBaud PAM4 applications and supports the Institute of Electrical and Electronics Engineers (IEEE)/Optical Internetworking Forum-Common Electrical I/O (OIF-CEI) standard specific measurements.
This solution complements Tektronix’s optical pulse amplitude modulation (PAM4) analysis tools for sampling oscilloscopes, giving design teams efficient test solutions for all stages of the optical transmitter workflow.
The new product allows R&D and system engineers to more easily troubleshoot their optical devices by adding powerful debug capabilities. It also helps them in software clock recovery for PAM4 and non-return to zero (NRZ), triggering, error detection, and capture time correlated or contiguous record of a signal.
The DPO7OE1 offers 33 GHz optical bandwidth for 28-GBaud PAM4 debug applications. It can also be used for legacy NRZ applications. Analysis packages support standard optical measurements including aspect-oriented programming, optical modulation amplitude, eye height and eye width as well as PAM4 IEEE and OIF-CEI standard specific measurements including transmitter and dispersion eye closure quaternary.
