Steve,

The fist pic shows PE with high pass filter applied. The green line is filtered out low frequency part (probably worm gear problem, since the dec drift (not shown on graphs) was linear).

The second pic presents raw data, and the third is frequency spectrum (the peak in the middle is due to worm(PE), the right-most one is that low freq component)
