Anritsu Company Introduces Enhancements for Signal Quality Analyzer MP1900A to Meet High-speed Interconnect Designs

12/29/2017

Anritsu Company introduces two options for its Signal Quality Analyzer-R MP1900A BERT series that have been developed for more accurate and efficient testing of 100G/200G/400G Ethernet network interfaces, and PCI Express Gen4 and USB 3.1 bus interfaces. The Variable ISI MU195020A-040/041 option upgrades the Emphasis function of the MP1900A’s internal Pulse Pattern Generator (PPG) for evaluation of high-speed interfaces, backplanes, and cables. To support USB 3.0/3.1 receiver testing in accordance with the serial interface standard, Anritsu has developed the USB Link Training Software MX183000A-PL022 for the MP1900A, as well.

Integrating the new Inter Symbol Interference (ISI) option into the MP1900A allows engineers to more easily and efficiently evaluate high-speed interfaces, backplanes, and cables. The Variable ISI option uses the 10Tap 20-dB variable Emphasis function which features the industry’s most flexible signal controllability to emulate CEI-25G/28G-defined signal path transmission losses. It allows ISI emulation using the De-Emphasis function to close the eye, so engineers can simply adjust the ISI effect without using an actual loss channel. This allows the impact of transmission path losses on the test device to be evaluated simply, without testing PC boards. The option also permits auto-calculation of the best Pre-Emphasis setting based on S-parameter files to compensate for ISI caused by cable connections and test fixtures, enabling engineers to counteract loss in the channel and open the eye. Both functions help reduce development cost and time.

Recognizing the importance of USB Link training when measuring USB interfaces, Anritsu has developed the built-in Link Training function for the Signal Quality Analyzer-R MP1900A BERT to create an all-in-one protocol aware USB 3.0/3.1 Rx test solution. It leverages the built-in Error Detector (ED) that features low intrinsic jitter to produce high-quality waveforms and sensitivity to support highly reproducible measurements of the PHY-layer of USB 3.0/3.1 devices. It can transition to the MP1900A’s evaluation device measurement mode, and when used in combination with the Link Training Status State Machine (LTSSM) Log Analysis function, evaluating USB device receivers is dramatically reduced.

Featuring the built-in 32-Gbit/s PPG and ED, the MP1900A high-speed BERT supports design and testing of high-speed interfaces, such as PCI Express and Thunderbolt, as well as 100G/200G/400G Ethernet and USB. With the PPG supporting a 10Tap Emphasis function for testing the effect of transmission path loss, plus jitter and noise addition functions, and a high-sensitivity BER measurement function, Anritsu’s MP1900A series is ideal for measuring high-speed interfaces. A flexible 8-slot modular main unit provides a platform that expands as test needs and standards evolve, providing excellent test instrument return on investment (ROI).
