Hey hardik,

This sounds like a hardware problem.  I have heard of this error when the external connections of the device are not connected tightly.  I would check all of your connections and see if the error shows up again. 

I have also seen this error occur when the grounds of the devices (the 8451 and the UUT) aren't connected together properly, so it is possible this could be your issue.

I hope this helps!
