    The “ANT-20 NEXT” software can be run as an alternative to the standard graphical user interface of the ANT-20. All you need to do to perform a measurement is select the type of path to be tested. All the important measurements for characterizing and quality analysis of the path are then performed automatically.

  • Page 12: Basic Information On Running Applications

    The “ANT-20 NEXT” software first determines the type of line. The ANT-20 is then automatically set correctly for subsequent measurements. To determine the line type, the TX signal of the ANT-20 (setting: TX clock internal) is offset by 10 ppm and the received clock signal measured.
  • Page 13 If the line operates with “re-timing”, the ANT-20 is automatically set to “Clock from RX”. This ensures that the line clock and the clock signal transmitted by the ANT-20 are identical. This setting avoids sporadic bit slips (ANT-20: LSS) that occur as a result of slight differences in the two clock signals.
