Equalization Processing Software

The PatternVu option adds four powerful components to the BERTScope Analyzer for the analysis of PRBS and user patterns:

CleanEye averages waveform data to present an eye diagram with the non-data-dependent jitter removed. This allows the user to view and measure data dependent jitter such as Inter Symbol Inference, giving an intuitive idea of the compensatable jitter present, for example. It is effective on any repeating pattern up to 32,768 bits long.

The Single Value Waveform Export utility converts the CleanEye output to an export file in Comma Separated Vector (CSV) format. The output file, of up to 10⁵ bit points, can be exported into Microsoft Excel or software analysis and simulation tools such as Stat-Eye or MatLab. This allows offline filtering of real captured data and the implementation of standards-based processing such as Transmitter Dispersion Penalty (TWDP) required by 802.3aq, the recent Long Reach MultiMode (LRM) 10 Gigabit Ethernet standard.

The FIR Filter equalization processor allows the emulation of the communication channel to view and measure the eye as the detector in the receiver would, by applying a software linear filter to the data before it is displayed.

The filter characteristics are controlled by entering the individual weighting coefficients of a series of taps in the FIR (Finite Impulse Response) filter. Up to 32 taps can be programmed to allow fine resolution of the filter shape, and it can be applied to repeating patterns up to 32,768 bits long.

Single Edge Jitter Measurement allows truly deep BER based jitter measurements to be applied to individual data edges above 3 Gb/s for the first time. The Jitter Peak measurement function enables computation of jitter on a single edge in the pattern, selected by the user. The resulting jitter measurement excludes data-dependent effects, showing only the uncorrelated jitter components such as RJ, BUJ, and PJ.

The PatternVu equalization processor option is available on any BERTScope analyzer.
