Anritsu Demonstrates 32-Gb/s Signal-Integrity Test
January 29, 2013. Anritsu announced today that it is conducting live demonstrations of its 32-Gb/s test solution featuring the Anritsu MP1800A BER Testers during DesignCon. Anritsu said it is also displaying its VectorStar Vector Network Analyzer (VNA) platform.
“High-speed designs incorporating complex, high-frequency signals pose a tremendous challenge for signal integrity engineers. Anritsu is committed to providing the test solutions necessary to accurately and confidently verify these designs. We were the first company to support both jitter tolerance and generation of emphasis signals for 28-Gb/s interconnect technology, and we continue to lead the way in signal integrity testing,” said Hiroshi Goto, business development manager at Anritsu.
As shown in the 32-Gb/s demonstration, the MP1800A features the performance—including low intrinsic clock jitter of <350 fs (RMS) and a unique eye contour function—necessary for engineers to evaluate jitter, ISI, and crosstalk at signals up to 32 Gb/s and employ necessary countermeasures to ensure signal integrity. The demonstration also shows how engineers can use the solution to account for signal-integrity reduction for the transmitter and receiver circuits, ensuring the quality of the output signal and receiver tolerance to validate backplane and high-speed interface performance.
The MP1800A is configured with the MP1825B 4Tap Emphasis at another station in the Anritsu DesignCon booth. The solution supports easy changes to the pre-emphasis waveform amplitude, offset, and amplitude of each tap, for effective evaluation of the characteristics of high-speed interfaces below 10 Gb/s, such as PCIe, USB, and backplane Ethernet requiring pre-emphasis signals, as well as InfiniBand 26G-IB-EDR, CEI-28G-VSR, and other interconnect technologies in the 25/28-Gb/s band.
The VectorStar platform, with frequency coverage of 70 kHz to 125 GHz, dynamic range of 108 dB at 65 GHz and 107 dB at 110 GHz, and measurement speed of 55 ms for 201 points, is suited for broadband and millimeter-wave (mmWave) signal-integrity applications. At DesignCon, the broadband VectorStar ME7838A VNA and VectorStar MS4647A VNA are on display.
VectorStar was also referenced in an informative tutorial session entitled “Methods of Improving 3D EM Model Development and Associated Time/Frequency-Domain Measurements.” Dr. Jon Martens and Bob Buxton of Anritsu teamed with James Bell and Alfred Neves of Wild River Technology for the presentation, held Monday, January 28.
Also on display at DesignCon is the MP2100 BERTWave all-in-one BERT and EYE/Pulse Scope solution and the MS9740A optical spectrum analyzer, for evaluating XFP/SFP-type optical modules, laser devices, and optical cables used in optical communication systems. The MP2100 combines a BERT and sampling oscilloscope to reduce gating time by 90% compared with conventional BERT equipment, and the EYE/Pulse Scope function is 300% faster. The MS9740A can measure optical devices in <0.2 s and has ≤70-dB dynamic range.
