Relative Level Measurement using PCI-4462

[lyeflyer]

Hi, everyone.

I would like to create a Labview program to test the my radio volume using PCI-4462 and Sound/Vibration Measurement Suite 2011.

Before this, I always use Panasonic VP-7722A to test the radio's volume steps.

There are 31 (0-30) volume steps and I always set the relative level at step 30, at which my reference is 0dB.

Then the volume will be tuned down one step by one step until step 0 for check its attenuation (dB) at each step.

However, I coundn't find the way to perform the same steps using PCI-4462 and Sound/Vibration Measurement Suite 2011 so far.

Kindly need any expert to help and advise on this.

Thanks.
