ISO Human exposure vibration analysis

We are working on weighting WBV signal as well.  Has anyone successfully developed the code to weight WBV signals.  Seems it could be done in two ways, developing you own filter to weight the continous signal which has been done in by others (in Matlab think).  Or octave banding the continous signal and applying the weightings to the banded signal  .I can’t seem to get the correct weighting using the 1/n Octave Band VI, I have the 1/N octave band VI set to look at 0.5 - 100Hz component of the signal but when I apply the weighting afterwards my signal is strange.  I think my problem is getting the correct signal out of the 1/n octave band, not applying the weighting per se.  Any help would be much appreciated. 

Thank You,

Pete Johnson
