What is the difference between a short-range transmitter with an air core versus a short-range transmitter with a ferrite core?
HARDWARE: A. The biggest difference is range. Both transmitters enable six degrees-of-freedom sensor tracking, but the ferrite version produces a stronger signal than the air core version. At 17 inches of separation, the position and angular noise for a ferrite transmitter will be about one half that of the air core. For this reason, we recommend that the air core transmitter be used in very short-range applications, such as tracking a sensor referenced to a transmitter that is no greater than 8 -12 inches away.
