The N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE-LR4 and -ER4 test specification. In order to do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source are required to operate together to achieve a compliant, repeatable optical stressed eye. Automation of the time consuming calibration of the optical stressed eye results in time savings of more than a factor of 10, compared to the manual setup.To control the whole set up, a turn-key software with test-automation is used, which limits the time consuming development of individual test software development.
