Figure 22. Turn-On Bias Stability Panel
Another key performance characteristic of gyroscopes is their
turn-on-to-turn-on bias stability, which determines the range of
expected offset values between each power cycle that can be
factored into the development of application specific algorithms.
The
Turn-on Bias Stability
panel allows you to adjust the
supply voltage for this test to match the intended application
voltage. To record the data from this panel, ensure that the
Record Bias Run Data
box is checked before clicking the
View
Turn-on Bias Stability
button. You are then prompted to enter
a file name for the data upon completion of the specified number
of turn-on cycles or upon clicking the
Stop Data Record
button.
While the test is running, the
Min
,
Max
, and
Std. Dev.
boxes
are updated upon the completion of each power cycle.
It is recommended that this test be run for several hours and in
a temperature-stable and disturbance-free environment. Any
rotational motion applied to the gyro corrupts the results of this
experiment.
