  • Analysis Type
    • Inlink
      • Send config and Read analog current
      • Summary histogram in log format with tags for the kind of measurement, tmiestamp and masks of enabled PP0, modules, and FEs from Inlink Scan
      • decode summary histogram and read back current values for the configured module
      • inlink OK: analog current greater than 130mA (per module)
    • Inlink/outlink
      • Preset BOC_LINKSCAN
      • Reading back data to/from the formatters
