This is a post as a reference to others on how I resolved my ghosting issues. Well mostly resolved, I still have a 1mV per 1V adjustment. Works fine with my hardware in between. You may want to tweak the values around to get none at all. Feel free to post your values and how you fixed ghosting issues. I only added Crosstalk as a reference in subject for those that are unaware of ghosting.

I'm reading a sine wave generated by a AO DAQ and reading this same signal with another AI DAQ and a DMM at the same time. AO is set at 0.65V AI RMS reads 0.5VÂ±0.0056 DMM reads 0.46053V Â± 0.00001 0.65/1.414=0.46 so the DMM read is accurate. What makes the RMS LabVIEW function not reporting the accurate information? Could it be the Glitch Energy affecting the read? On a side note, I also need an accuracy of 0.2%. AO generates a 3KHz signal at 0.65V (450KS/s @ 150S/Buffer). AI reads at 90KS/s at 15KS/channel. DMM a 34401A is set VAC. Thanks
