I am using SCXI-1121 and SCXI-1163 modules with SCXI-1000DC chassis. I have developed my application in Labview 7. I input an analog signal and upon meeting a certain condition activate channel zero of relay module.I measured the time between meeting certain condition and activation of relay with another precise system. I repeated this process several times. My problem is that the time between meeting certain condition and activation of relay varies from seven to nineteen milli second. Why am I not getting the same time after each repetition? Please advise.
