The sample update rate in the ADIS16265 is 2048SPS, when SMPL_PRD[7:0] = 0x00. The Data Capture window is reporting this 512.033 SPS, which is incorrect. It appears like this error is not influencing the data acquisition rate, as a 8192 sample record took approximately 4 seconds to complete.
We have identified the root cause of this issue and have addressed it in a new version (v1.17.8) of the IMU Evaluation software, which should be on the EVAL-ADIS and EVAL-ADIS2 web pages by 2/15/17. Here is the location that the new version will be posted at:
