I've attached data we collected from the PDP during a match at the SCRRF Fall Classic. Note that each channel has a small steady state error, which will be calibrated out in a later firmware update.
Hi Joe,

Do you think you have the DS log for this match that you could attach or send to me?

Thanks,
