Thanks a lot for your reply.
After the PXI controller 's suddenly power off when performing adjustment , we restart the OS and found the PXI 5610's error infomation in the MAX : Error -200437,External calibration constants are invalid,and he card cannot be used in our Auto-Test-System anymore. I guess the calibration data in the EEPROM was missed or uncompleted,but i have no relevant softwre tools to read or write PXI-5610's EEPROM.
Could you give me some suggestions to solve this BIG problem? Thanks.
