I am using the dynamic signal analyzer.vi but this vi has the output as single precision. How can I change this to DBL precision? If I change the representation from single to double in the AI buffer read.vi labview returns ilegal operation and crash. I have labview 5.1 on windows 95 and one AT-MIO16XE50 DAQ board.
Thanks in advance
Ricardo.

Probably by changing the data type that lvdaq.dll expects to write to is causing the crash. I can't test this since I have only 6.1 installed now. In any case, since the daq card is only 16 bits, the single precision is probably adequate for AI Buffer Read. If you do need the greater precision later on, you should be able to change representation in any one of the upper level VIs.
