LabVIEW SCXI 1100 anomaly Dear all,
I have run into a truly bizarre anomaly when reading from an SCXI 1100 card with labview 6.1. I have been using labview for over 4 years and have never seen anything like this. I wonder if anyone can help me. I have an application with many temperature readings. I have a dedicated SCXI 1102 card for most of these but I have not got enough channels so I have been using an SCXI 1100 card for the spillover. I noticed that the readings I was getting for this card were fluctuating a lot, much more than they did when I checked the signal in MAX. Also, I noticed that when I acquired from the 1100 card in a calibration routine elsewhere in my application, the signal wasn�t fluctuating at all. The only difference between the calibration routine and the main application is that in the main application I am acquiring over 40 channels whereas in the calibration routine I am taking only 3 or 4 at a time. The code I am using is exactly the same in the two locations� only the number of channels being acquired is different. The signals from the 1100 are affected but the signals from the 1102 are fine in both routines. I have repeated this problem in two different locations. I have also noticed that it affects pressure signals on the SCXI 1100 as well. Can anyone offer me any advice on this? Regards, Barry Brophy
