1.Scroll through the recorded data and note the changes in activity in the raw biceps channel (Biceps). Note also that placing weights on the hand gives rise to little or no activity in the triceps muscle.
2.Choose a small part of the "Biceps" activity and examine it in more detail by setting the Horizontal compression to 1:1 and clicking Autoscale. Note that the raw EMG signal is composed of many partly-overlapping spikes.
3.Note the relationship between the raw trace (Biceps) and integrated trace (RMS Biceps). The height of the integrated trace reflects the overall activity of the raw EMG signal, and gives a simpler view of the muscle's electrical activity.
4.Use the Waveform Cursor and Value panel to record in the table the amplitude of the integrated trace as weights were added and removed. The height of the trace correlates with the force produced by the muscle.
