WB SE Attenuation

 Unique technique used to measure insertion 

loss (attenuation) across a selected range

WB PSD Noise

  Crosstalk/RFI detection from live pairs

 Frequency band selection (ADSL2+ 2.2MHz, 

to VDSL2 30MHz)

  Blue plot shows peak levels since start of test

  Black plot shows live levels

Frequency Band Selection

(ADSL2+ 2.2MHz, to VDSL2 
30MHz)
