(1)
Delay from sensor event to analog output is fixed for all channels, and referenced as a
"group delay". In the case of Accelerometer channels, this delays consists of the following
elements: a) Acc Filter (2 ms), b) Digitization Delay (41 ms), c) SinX/X Correction (27 ms),
and d) Analog Low Pass Filtering (26 ms).
(2)
This parameter relates the nominal uncalibrated voltage differential for an inertial
displacement of 1 g.
(3)
Sin(X)/X correction is applied to each channel for cancelling the distorting effects of the DAC
sampling process.
