Hello,
 
When I try to perform Self Calibration of PCI 6341 its first give me following error 
 
The device could not be calibrated. Status Code: -201295
 
and sometimes it give me the following error
The device could not be calibrated.
Status Code: -50103
The specified resource is reserved. The operation could not be completed as specified.
 
 
Another Problem is 
 
I was doing a real-time experiment and it was working fine, but suddenly my AO value of PCI 6341 became constant as 13.1 V. I am not sure why this problem occurred I am providing different values from my Simulink Desktop Real-time but it's constant 13V.
 
I am afraid my board is burnt out. All other ports are working fine. PCIe 6341 has two AO ports and out of them 1 is working fine but the other has that problem, in the morning both ports have been working well since last week.
