Hello,
I am currently using the swept sine FRF from the sound and vibration toolikt with a NI USB 6259 device. Currently I have integrated a controller and increased my settling time between points to 20seconds and my integration time to 15seconds. With the FRF generated in labview is this just the response channels integrated value at each frequency or is it (response/stimulus) at each frequency. It appears to be just the repsonse channel however when I increase my forcing amplitude the numbers do not match, I believe this is due to my integration vlaue as it takes time for my controller to correct the value.
Is there a way to delay the measurement for the FRF when plotted in labview?
Your help is most appreciated
Regards Tanju
