Hi I am trying to use MyRIO to measure sound pressure level using an electret microphone connected to the audio input and the Sound and Vibration Toolkit (all software version 2019) I am using the FPGA high throughput personality to acquire at 44kHz as shown attached Then I scale the signal, I apply frequency weighting and I compute the LEQ using the appropriate VIs from the S&V Toolkit But if I select A-weighting the "SVT A, B, C Weighting Filter (Fixed Rates) VI” generates an error (shown in the attached file). If I select linear no problem. Of course I have also tried updating “channel info” accordingly Any ideas why? Are there any incompatibility issues between MyRIO and SV Toolkit? Any help would be much appreciated. Thanks! Best regards Guillermo

problems using Sound and Vibration in MyRIO

I am trying to use MyRIO to measure sound pressure level using an electret microphone connected to the audio input and the Sound and Vibration Toolkit (all software version 2019)

I am using the FPGA high throughput personality to acquire at 44kHz as shown attached

Then I scale the signal, I apply frequency weighting and I compute the LEQ using the appropriate VIs from the S&V Toolkit

But if I select A-weighting the "SVT A, B, C Weighting Filter (Fixed Rates) VI” generates an error (shown in the attached file). If I select linear no problem. Of course I have also tried updating “channel info” accordingly

Any ideas why? Are there any incompatibility issues between MyRIO and SV Toolkit?

Any help would be much appreciated. Thanks!
