Hello,
I am performing modal analysis using a impact hammer, USB NI 9233 cRIO DAQ and Sound and Vibration assistant. The steps have been set in Signal express as DAQ Acquire =>Trigger=>Filter=> Power spectrum => FRF => Save to Ascii.
I am facing two problems which I cant understand. Inspite of selecting data for saving as an ascii file it keeps giving me an error saying data file needs to be selcted. I selected the filtered data, FRF, coherence in separate save as ascii steps. Also the filter issues me a warning that the triggered data is not contiguous. What does this mean? I have selected the option of continuous samples in the DAQ Acquire tab. Do I need to change something else? I tried using both IIR and FIR filters and it still displays the error that Signal is not contiguous.
Thankyou.
