To use SinCos encoder with analog sine and cosine voltage outputs, select the SinCos encoder from Granity's feedback device list {{param|FBD}}. The interpolation factor determines how many times the resolution is increased from the base resolution.

In addition to choosing interpolation factor, the feedback device resolution parameter {{param|FBR}} need to be set accordingly: multiply the base resolution with interpolation factor. I.e. with 1000 line encoder and 16X interpolation, set FBR to 16000. | In addition to choosing interpolation factor, the feedback device resolution parameter {{param|FBR}} need to be set accordingly: multiply the base resolution with interpolation factor.
