PAM4 Test Solution

High-Quality

High-Quality Data Output with High-Speed Tr/Tf and Low Intrinsic Jitter

The PAM4 PPG MU196020A supports output of low-noise and low-distortion high-quality data signals with a high Tr/Tf speed (20 to 80%) of 8.5 ps, a low intrinsic jitter of 170 fs rms, and a high analog bandwidth for generating wide open Eye PAM4 waveforms and high-reproducibility measurements.

4Tap Emphasis Output at 20 dB max

The optional 4Tap Emphasis function built into the MU196020A can generate the Pre-Emphasis and De-Emphasis signals required by each standard for maximum rates of 64.2G. Since each tap can be changed independently up to 20 dB, corrected waveforms for various transmission paths can be output with good reproducibility.

116-Gbit/s PAM4 Signal Error-Free BER Measurement using High Input Sensitivity Function

Combining the PAM4 ED MU196040B with the PAM4 PPG supports BER measurements of 116-Gbit/s (58 Gbaud) PAM4 signals. Error-free BER measurement is achieved by the industry-best high sensitivity performance of 23 mV @ 26 Gbaud and 36 mV @ 53 Gbaud. The resulting high-accuracy BER measurements make it easy to troubleshoot previously difficult-to-analyze PAM4 devices. In addition, true DUT performance can be verified because even CEI-112G-VSR-defined worst-case stressed signals can be received at low-error rates (<E-8), exceeding the specifications.

Auto-Search Function  UPDATED

Upper, Middle 및 Lower Eye 측정 지점(전압 임계값 및 위상) 외에도 최적의 Equalizer 설정을 자동으로 감지하여 최상의 BER 결과에 필요한 조건을 자동으로 감지합니다. 또한 PAM4 Symbolic Logic 및 Gray Coding 조건의 자동 검출은 입력 PAM4 Symbolic Coding에 대한 패턴 조건의 자동 평가를 지원하여 보다 효율적인 측정 환경을 제공합니다.

Expandability

The MP1900A series is an 8-slot, modular, high-performance BERT.
Installing multiple 64G PAM4 PPG module boards in the slots provides the performance for measuring not only 400GbE systems but also future 800GbE systems as well. This flexible expandability helps customers maximize product development-cost efficiencies and bring products to market early.

PAM4 Signal Jitter Tolerance Test using One MP1900A

PAM4 Jitter Tolerance Test

Supports detection and analysis of FEC Symbol Errors

The input data is captured when the number of FEC symbol errors exceeds the threshold setting. The causes of FEC-uncorrectable errors can be analyzed from the captured data.
