#83436 - Another idea Responding to: ???'s previous message |
Hi Raghunathan,
I don't know if this will help or not, but the first thing I'd look to do is use a bipolar DAC with a ±10V output. Then just calibrate the midpoint of the ripple count to zero. Yeah. I would try setting the zero point of the ripple counter to full CCW rotation, and calibrate the zero point of a bipolar DAC to correspond to 2000° of CW rotation, making sure to have enough room to go as far as 4000° of CW rotation. Good luck, Joe |
