Total gyro bias, 16490

I recently recieved an ADIS 16490 and am seeing a X gyro bias of around 0.1 deg/sec (~340 deg/hr) when just sitting on a table in any orientation.  There are also smaller but still significant Y and Z biases.  I ran a moving average of the gyro output and expected to see something like Earth rate (15 deg/hr), but that is swamped out by this big bias.

 

The bias stability seems ok, but is this amount of total bias normal?

 

Thanks
