The signal options has been made part of the Advanced Features, and as such is not enabled by default, at least not at the moment...
To gain access to this setting, once within the NVH test software please choose "Options > Advanced Options". Here, choose the Features tab, and check the Enable Advanced Features box.
You will see the Signal Options setting will now have appeared on the Setup tab of the NVH test page.
