DescriptionThe N4917CPCA software provides an automated standard compliant stressed receiver sensitivity test according to the common public radio interface (CPRI) 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. This stressed eye is then fed to the receiver under test, where bit error ratio or jitter is measured under the stress conditions as defined in the standard.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.''
