Is there a manual for RSAVu software? It doesn't appear to have the same menu structure as my RSA6114A.

Is there a manual for RSAVu software? It doesn't appear to have the same menu structure as my RSA6114A.

There are only release notes available for RSAVu. However, it is based on the user interface of the RSA3408A.
Download that manual and use it as a guide. It will be the same interface as RSAVu. Link: User Manual
