  • Settings:
    • Startup Settings: DUT state at measurement start; required if AUX provides no parameters during capture.
      • Lane Number: Number of lanes in use (required). Default: 2 lanes.
      • Main-Link: Main-Link rate (UI shows Gbps/lane). Default about 2.97 Gbps/lane.
      • TPS Type / Control Symbol: Training pattern type and control-symbol mode. Default: TPS3 / Enhanced Mode.
      • DP version / eDP version: Aux Channel decode version.
      • Ignore Aux Channel Setting: Ignore AUX-provided settings. Default: cleared.
      • No Link Training / Disable Descramble / ASRE / Not Force Alignment: Wake without TPS, skip descramble, Alternate Scrambler Seed Reset, lane alignment options. Default: all cleared.
    • Probe Connection: Main Link probe vs Lane / P-N mapping; swap channel numbers and P/N as needed.
    • Filter: Drop commands or pixel data to reduce volume. Default: all filters cleared.
      • Filter Fill Start / Fill End
      • Filter Dummy Data
      • Filter TPS (TPS 1–4)
      • Specific Filter (Pixel Data): All or every Nth frame (max 128).
    • Option:
      • Fold TPS Symbols: Fold consecutive TPS in the report and show counts. Default: checked.
      • Show Idle Pattern. Default: cleared.
      • Ignore Unknown During TPS: Ignore Unknown between Sleep–TPS–Scrambler Reset while lanes are not yet aligned. Default: checked.
      • Detect TPS1: Enable TPS1 detection. Default: cleared.
  • Trigger settings:
    • Trigger On: Event Trigger or External Trigger In; Main-Link and Aux Channel tabs. When checked, the trigger tab is enabled (Enable). Default: cleared.
      • Main-Link: Lane, Simple Trigger (K-codes/events), Pattern Trigger (MSA/SDP, etc.). Pattern Default is often MSA; XX = don't care per nibble/byte.
      • Aux Channel:
        • Simple Trigger: Request Start/End, Reply Start/End, Timeout. Default: all cleared.
        • Pattern Trigger: Enable and open the Pattern Trigger dialog via the gear (see popup notes). Default: cleared.
          • Packet type (e.g. Request).
          • CMD: e.g. Any CMD.
          • DATA: Byte 0–15 (XX = don't care). Dialog Default: most bytes XX. Open this dialog from Trigger On → Aux Channel → Pattern Trigger via the gear. Choose the packet type (for example Request), CMD (for example Any CMD), and set a DATA pattern for Byte 0–15. Enter XX for don't-care bytes.
