Abstract
A transmission system for a measurement device on a coordinate positioning apparatus comprises a station (18) mounted on the measuring device (10) and a station (20) mounted on the coordinate positioning apparatus (22), wherein the stations communicate with each other using a spread spectrum radio link, for example frequency hopping. The station on the probe sends a regular signal and on receiving the signal the station on the coordinate positioning apparatus synchronises its clock and sends an acknowledgement signal. Measurement data is either sent in the regular signal or in a measurement event driven signal.

A transmission system for a measurement device for a coordinate positioning apparatus comprising:
- a first station for mounting with one of the measuring device and the coordinate positioning apparatus;
- a second station for mounting with the other of the measuring device and the coordinate positioning apparatus;
- wherein the first and second stations communicate using a spread spectrum radio link.
A transmission system for a measurement probe for a coordinate positioning apparatus, comprising:
- a first station for mounting with one of the measuring device and the coordinate positioning apparatus;
- a second station for mounting with the other of the measuring device and the coordinate positioning apparatus;
- wherein the first and second stations may communicate on different frequency channels and wherein if the second station hears significant noise on a certain frequency channel, it will hop to another frequency channel.
