DataLITE
Wearable Data Recorder & Wireless Sensors
Explore muscle and movement analysis, both within and outside the boundaries of traditional testing environments.
This new concept has significant advantages over more traditional systems where the user is restricted by the length of cables or wireless ranges back to desktop receivers.
DataLITE Interfaces
DataLITE provides a selection of three interfaces. Each is capable of recording up to 24 analogue and 12 digital channels of data. If more is required, two or more interfaces can operate in the same environment.

RF Channel Optimisation Test
A new RF Channel Optimisation Test is an easy way to detect errors on all 32 frequencies available to DataLITE and determine the optimum combination of RF Channels to use.
DataLITE communications use 4 frequencies out of a possible 32 within the range of 2.403GHz to 2.480GHz; the choice of 'RF Channel' number selects which 4 to use.
Because this frequency range is also used by many other devices, such as Wi-Fi and mobile phones, there is a good chance that if the distance between the Dongle and associated sensors is significant, some communications will be lost due to another device transmitting on the same frequency. DataLITE devices reduce the effect of interference by continuously frequency hopping between 4 frequencies using built in error detection and data recovery.
The RF Channel test performs multiple transmissions of data on all available frequencies in sequence without using any error correction. A result of 100% means that all data transmissions on that frequency have been successfully transmitted and received. The ideal 'RF Channel' to use would be one where all 4 frequencies used by that RF Channel are 100%.
DataLITE Wireless Sensors
DataLITE sensors are completely wireless allowing total freedom of movement. Precise measurements include real-time joint angular movement, EMG analysis and many other associated physiological measurements.
