Trigno Recharging Base Station
(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.
(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 delays consists of the following elements: a)
Sensor Filter (1.5 ms), b) Digitization Delay (41 ms), c) SinX/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) Sin(X)/X correction is applied to each channel for cancelling the distorting effects of the DAC
sampling process.
