1)
The Trigno System is designed with 16 data slots for wireless transmission. Sensors can occupy up to 4 slots
depending on the sampling rate settings.
2)
Sampling period is the precise time elapse between samples in milliseconds. The sampling rate is a rounded
expression of 1/”sampling period” expressed as samples/second (sa/sec).
3)
RMS window is the period of raw signal that is captured and process to produce singular RMS value.
4)
RMS update rate is the rate at which the RMS calculation is updated, expressed as samples/sec (sa/sec).
5)
Analog EMG Sensor Butterworth filter bandwidth: 2 pole high pass corner, 4 pole low pass corner in Hz.
6)
EMG signal input range of sensor in millivolts.
7)
sensor resolution depth across input range.
8)
IMU bandwidth determined by onboard digital low pass filter
9)
Accelerometer signal input range in “g” (i.e. 9.8 m/s
2
)
10)
Gyroscope angular rate input range in degrees per second (dps).
Denotes raw EMG signal acquisition.
Denotes onboard RMS calculation of the EMG signal.
Denotes onboard 3 DOF accelerometer data.
Denotes onboard 3 DOF gyroscope data.
Denotes analog output supported mode.
