Noise
Tab
The
Noise
tab configures the
ADXRS290
for real-time angular
velocity monitoring and noise calculation. This tab contains an
oscilloscope-like interface that shows the output of the gyroscope
and allows you to adjust the relevant parameters, such high-pass
filter, low-pass filter, and tested axis for real-time show and noise
calculation (see Figure 17).
After configuration, click the
Calculate RMS Noise & Noise
Density
button to begin noise calculation. To prevent software
conflicts, many of the options and tabs are grayed out or
disappear until the system finishes the noise calculation.
Ensure that the evaluation board is in a vibration free
environment when you test the noise performance. Any
vibration on the evaluation board may cause the fault noise
result.
Calculate the
RMS Noise
by taking the standard deviation of
the selected number of data points. More points provide more
accurate results, and you also need to wait for a longer time to
get the noise performance. The number of default points is
10,000.
