Oscilloscope


The figure on the left displays the signal quality levels of all connected nodes and the shape of the electrical signal of three selected network nodes.



  • Node 2: Master station at the “left end”
  • Node 60: Slave station in the “middle”
  • Node 90: Slave station at the “right end” of the network

The oscilloscope view clearly displays the signal distortions caused by signal reflections.


Please Note:
You can use the oscilloscope’s curser to closely estimate the actual distance (in meters) between the node and the location of the reflection.


Also, please notice that the distance to t
