  let's assume that you use an a147 as lfo and
  an a138a linear mixer (the latest revision).
  the sinewave has a varying amplitude of -5/+5 volts.
  feed this sinewave into input 2 of the a138a and
  set the attenuator for input 2 to 12 o'clock position.
  this reduces the lfo amplitude to -2.5/+2.5 volts.
  now set the attenuator for input 1 also to 12 o'clock
  position, without inserting a cable into input 1.
  this will add +2.5 volts offset to the mix.
  the result at the mixer output is a sinewave with
  an amplitude of 0/+5 volts.

  best wishes

  ingo

  can't go over 5v or under 0v?? somehow my brain and the description 
  in the pdf are not connecting.
