ADIS16475-3 drift error

Hi all,

 

Our customer evaluate the 3set of the ADIS16475-3/PCBZ .


From "Figure 10. Gyroscope Allan Deviation, TC = 25°C, ADIS16475-3" in the datasheet,
we know about 7 deg/h @ 100s periods sampling.

 

We expect the following drift value in static.

 7 deg/h / 3600s * 100s = +/- 0.1964 deg @ 100s periods sampling.

Is it correct ?

 

Following (attachment) is customer measured data @ 100s periods samplng ,

 x axis : <-0.1deg < 0.1964 deg ; Expected value

 y axis : <-1.2deg > 0.1964 deg ; Not expected value 

 z axis : <-3.75deg >0.1964 deg ; Not expected value

Are they within the typ specification?
, especially the y & z axis data ?


Best regards,

sss
