    From this tab, select/configure to control the following features: ▪ Specify the Baud rate. ▪ Specify the signal modulation type: NRZ/PAM4 (if available/supported). ▪ Enable/Disable the FEC feature. ▪ Check the Rx amplitude range supported by the error detector. ▪ Select the 3 or 7 taps FIR filter mode.

  • Page 13: Tx Control In Advanced Mode

    ▪ Enable/Disable TX control for each channel (TX ON/OFF). Once turned off, the control of TX settings is disabled: channel control is locked from any selections, and TX output is turned off (Figure 17). ▪ Specify the TX signal pattern. The supported TX patterns are all available in the dropdown list, depending on the BERT model in use.
  • Page 14 ▪ TX Pattern: Supported TX patterns are all available in the dropdown list, depending on the BERT model in use. ▪ FFE Taps: Tap control offers the following on TX: o Scaling between 60% and 120% o 3 FFE taps (in 3-tap mode) and FIR filter 7 taps (in 7-tap mode).
  • Page 15 Optimal configurations and calibration are only available in 3-tap mode. The Channel NOTES: Emulation feature is only supported in 7-tap mode. ▪ Channel emulation. To emulate channel loss, start by clicking the emulation button. When enabled, the emulation button will turn to green. You can insert the magnitude of the loss at the Nyquist frequency (half of the configured baud rate) in decibels.

  • Page 16: Rx Control

    Apply to all channels option This option is used for the TX and RX settings, and transceiver control if available. When selected, it applies the configuration of the current channel to all BERT channels. For example, pressing “Apply to all” on the TX window will apply all TX configurations displayed in this window to every other channel.

  • Page 22: Platform Specific Measurements

    Figure 36-1: Error tracking vs. time Platform Specific Measurements MultiLane offers both emulated and real hardware FEC-supporting devices. Available FEC measurements depend on the HW revisions and the type of BERT in use. In this section, the supported specific measurements will be detailed.

  • Page 23: Real Hardware Fec Measurements

    If the LK is valid, another pop-up window will appear, informing you that the LK has been applied. Figure 39: License key added Figure 40: FEC features enabled After you have applied your LK, the BERT should be disconnected and power cycled. Full hardware FEC features will then be accessible and ready to use.
  • Page 24 When FEC is enabled, you can change the X and Y axes to the supported graph combinations where instant and accumulated bit counts are supported and can see the results of the measurements in the details section. SER measurements are also supported in FEC mode; corrected codewords with symbol error distribution are displayed.
  • Page 25 To enable measurements, select a value for both the X and Y axes*. Different options for the X axis selection are supported, but only one can be selected per measurement, while more than one Y axis can be selected and displayed simultaneously. The scale of each Y axis selected will be displayed on the left of the graph.
  • Page 26 There are three measurement blocks for SER: 1. Instant Codeword Symbol: the symbol error rate distribution for the link under test in a specific 100 ms window. Refreshes 10 times per second. 2. Accumulated Codeword Symbol: the sum of total symbol error rate distribution for the link under test, accumulating from t =0.
