This equipment is borrowed from Institute for Sports and Biomechanics at SDU. The Myon equipment gives an analog voltage as output, that must be sampled for further processing. We normally use an AD Instruments Powerlab 16/35 - 16 Channel A/D converter from Medico Lab at TEK.
The most important technical specs are [1]:
- Measurement delay from input electrode to output BNC connector is 16ms.
- The wireless pods samples the electrode voltage with a resolution of 12 bits, sampling rate 4000 Hz.
- Output on the BNC connectors is a voltage of +/- 2.5V.
- The gain is g=500 (for our specific model). The electrodes on the wireless pods have an input range of +/- 5mV.
- The input electrodes on the wireless pods have an input filter with a bandwidth of 5 to 500 Hz.
Example: a measured voltage of 0.3V on the output BNC connector corresponds to an electrode input voltage of 0.3V / 500 = 0.0006V, or in micro volt: 600uV
