6 / 23 page 06 | Keysight | N5990A Test Automation Software Platform - Data Sheet Compliance test and characterization Options 101 and 201 simplify PCI Express receiver and transmitter characterization as well as compliance testing. The PCI Express receiver tests (N5990A Option 101) fully support Keysight’s M8020A and N4903B J-BERT high-performance serial BERTs. This ensures you can test PCI Express 1.1, 2.0, and 3.0 receivers ef- ficiently. For the test coverage see Table 1. Receiver jitter tolerance tests complement transmitter tests Option 101 provides the important jitter tolerance test. In the test station setup shown in Figure 6, J-BERT’s built-in jitter generator is used to insert the jitter components which are required by the compliance tests. Transmitter test are conducted with a suitable Infiniium oscilloscope and application (N5393D). The oscilloscope is also used for the calibration of the test setup. The N5393D software is integrated into the N5990A test automation and enhanced with Option 201. This lets you select test parameters conveniently on the PC controller. A consolidated test report is provided, comprising receiver and transmitter test results. The controller PC can be used to display and analyze oscilloscope data too, so that productivity is further increased. Link Training Suite The PCI Express Link Training Suite (N5990A Option 301) offers an easy and quick set up of the PCI Express loopback training sequences as well as the signal parameters. It is ideal for debugging and troubleshooting. The generated sequences can be imported in the test automation. Link Equalization Tests The PCI Express Link Equalization Tests (N5990A Option 501) with the J-BERT M8020A use interactive link training. The tests verify the proper transmitter equalization negotiation capabilities of an add-in card or a host system. Multi Lane Testing For multi-lane testing, the N5990A supports the 2100 Series switch system from BitifEye. Computer Bus Applications - PCI Express Figure 5.
