In your original post you mentioned that the two outputs should be 180 degrees out of phase. How are the two waveforms above not what you want ? These below are not always 180 degrees out of phase > Normal (same as CWG1A above): >=20 > +---+ +---+ +---+ > | | | | | | > -------------+ +---+ +---+ +---------------------- >=20 >=20 > Inverted -- GOOD!
