(INTERCONNECT) EVM in Percentage and dB do not match

  Hi,
  Below is a basic setup to verify the operation for modulation mapping and constellation diagrams. I use the results from the constellation diagram element to see the EVM. The EVM in percentage is 2.8% and in dB is -3.1 dB, which to me the dB value does not make sense. Could you provide some feedback on this? Thanks!
  
  Also, is it possible to draw the constellation points without the transition lines from one point in the constellation to another?

  Hi m.belchovski,
  Thank you for bringing this to our attention. It looks like the dB number is 10 times smaller. I will report this as a bug and let you know once it's fixed.
