Making octave plot in SVT to use g/SQRT(Hz) units

thanks a lot, I am trying to figure out how to add it to the library now.

will post updates when I get it to work... One comment: the SVT 1/3 VI's don't let me pick low frequency , 20Hz is the lowest I can go... I have to use 1/n and then I can just type the frequency and it's all good.

Looks like this attached VI does accepts the typed frequency, should work! thanks again.

update I just dragged from file manager into labview and the VI showed up.

I am trying to connect the output of the IEC 1/n octave analysis VI into this conversion VI and I get the following errors:

going from "octave spectra" to "octave spectrum"
You have connected an array data type to its element data type. This type conflict may be resolved by indexing the array to access individual elements of the array. Check for a tunnel on a loop that has indexing incorrectly enabled.
The type of the source is 1-D array of cluster of 2 elements.
The type of the sink is cluster of 2 elements.

and going from "octave info" to "octave info"
You have connected an array data type to its element data type. This type conflict may be resolved by indexing the array to access individual elements of the array. Check for a tunnel on a loop that has indexing incorrectly enabled.
The type of the source is 1-D array of typedef 'svt_Octave Info.ctl'.
The type of the sink is cluster of 8 elements.

help?

Here's a multi channel version of the code along with a polymorphic VI:

i finally got back to figuring out this VI, and now I seem to be getting the error finding the file named "svl_Spectrum Type.ctl"...

another problem, (might be related)

SubVI 'Octave PSD Conversion(N-ch).vi': subVI is not executable
The subVI is not executable. You must fix all errors in the subVI before this VI can run.

The "svl_Spectrum Type.ctl" should be installed in this directory:
C:\Program Files\National Instruments\LabVIEW 7.1\vi.lib\addons\NISVL\_NISVL.llb

Try browsing there to find this control. You might also consider performing a mass compile on some of your VIs if they are having trouble finding their subVIs. Check out the LV help file for more info on mass compiling.

i did a search, and i don't have the file svl_Spectrum Type.ctl on my hard drive... is it in a zip somewhere?

Since it is in an .llb, the windows explorer won't find it. You should be able to browse to the .llb, double click on it and see the files that are inside.

svl_Spectrum Type.ctl is not in the _NISVL.llb file

Hmmm...strange. Did that VI used to be there? You might want to try and perform either a Repair on your installation or uninstall and reinstall the Sound and Vibration Toolkit.
