Eric, is probably the best guy to answer this....but I will give it a shot. Freq offset is drift by an oscillator from the nominal frequency...this information is reported to the Hub which makes corrections accordingly. Symbol offet is a calculation used by the Hubs UCP (after acquisition/post-frame start) to make symbol delay corrections as bursts arrive at the hub. This information is also reported and controlled by the Hub.

Most HNOs wont get much use out of those values when commissioning a remote.
