Yo are right. The module does not amplify but has a miximum gain of +1
(attenuator mode) oder -1...0...+1 (polarizer mode). We went back to the
"attenuator" (i.e. 0...1) but forgot to change the specs on the A-132-2 info
page. To obtain an amplification of 2 the value of R5 (100k, just below the
offset control potentiometer) has to be increased (e.g. to 200k or 220k).

We will correct the specs on our website. Sorry for the confusion.

Best wishes
