Generating High-Speed Serial BUS Link Sequences with Signal Quality Analyzer MP1800A


Anritsu Corporation is starting sales of its newly developed High-Speed Serial Data Test Software MX183000A application for generating PCI Express and USB Link sequence patterns and testing Jitter Tolerance using the company’s popular Signal Quality Analyzer MP1800A series.

Using this application software supports efficient design and verification with Link sequence to control device status and jitter load tests required for evaluating PCI Express and USB interfaces.

[Development Background]

The explosive increase in data communications traffic requires large increases in capacity and speed of digital communications systems. Increasing the speed of typical BUS interface standards, such as PCI Express and USB, while assuring signal integrity is becoming more and more difficult and requires confirmation of margins using Jitter Tolerance tests.

High-speed BUS interfaces like PCI Express and USB require use of state machine control called LTSSM to perform communications between devices, so measuring instruments performing device tests must also support LTSSM.

Using the High-Speed Serial Data Test Software MX183000A generates the pattern signals required by the state transition for transitioning to the loopback status required by Jitter Tolerance tests.

Furthermore, as well as supporting precision tolerance testing using PHY device Jitter Tolerance tests with impressed SJ/RJ/BUJ, measurement times are also shortened by verifying device margins using low-rate estimated BER measurements.

[Product Outline]

The High-Speed Serial Data Test Software MX183000A controls the MP1800A, Jitter Modulation Signal Source, Pulse Pattern Generator (PPG), and Error Detector (ED) to perform state machine control of the high-speed BUS interface and Jitter Tolerance tests, elping cut test man hours and assuring accurate signal integrity measurements.
