The Trigno™ Wireless EMG System is a high-performing device designed to make EMG signal detection reliable and easy. Each EMG sensor has a built-in triaxial accelerometer, a transmission range of 40 m and a rechargeable battery lasting up to 8 hours. The system is capable of streaming data to EMGworks® Acquisition and Analysis software, and of generating 16 EMG and 48 accelerometer analog channels for integration with motion capture and other 3rd party data acquisition systems. Full triggering features further expand the possibility for integration with additional measurement technologies.

This revolutionary hybrid EMG/ACC sensor with motion artifact suppression (Patent Pending) provides an unprecedented combination of data in a reliable manner. Its design delivers the unchallenged high-quality performance expected from Delsys products. Now you may have freedom of movement and freedom from recording noise sources in one.

  1. Range is characterized in normal office environments. Interfering RF sources in the 2.4GHz spectrum, as well as absorptive objects occluding the RF communication path may degrade transmission distance. Stated range can be exceeded under favorable RF conditions.
  2. All data packets are guaranteed to by synchronized within the established sensor network.

EMG Analog Output Specifications:

Number of Outputs 16
Signal group delay 48ms
EMG Signal Range ± 5V
Effective EMG Signal Gain 909 V/V ±5%
Channel Offset (r.t.o.) ± 157 mV (max)
Baseline Noise  <0.5mV RMS
DAC Filter Bandwidth DC-500 Hz, 160 dB/Dec.
Passband Ripple < 2% with Sin(X)/X correction
Connector Type Scsi-68, Type II
  1. Delay from sensor event to analog output is fixed for all channels, and referenced as a “group delay”. In the case of EMG channels, this delay consists of the following elements: a) Sensor Filter (1.5 ms), b) Digitization Delay (41 ms), c) Sin(X)/X Correction (2 ms), and d) Analog Low Pass Filtering (3.5 ms).
  2. This parameter relates the detected voltage input at the sensor to the reproduced voltage at the EMG channel output.
  3. The channel offset is the sum of the base station offset and the EMG sensor offset.
  4. Sin(X)/X correction is applied to each channel for cancelling the distorting effects of the DAC sampling process
