Dedicated battery question

[willwork4fish]

I've just separated by 2 bow Garmin 106SVs and black box with dedicated wiring and a separate 100ah Ionic. The wiring goes from the battery to a Blue Sea fuse box up front and then the graphs powered to the fuse box, they are the only items on the fuse box. I've read and been told that it should help my livescope imaging (LVS32) to some degree. My console 106SV is still going to my cranking battery along with all of my other accessories. all 3 graphs are networked. Am I right to assume that any interference I was seeing is just likely due to the electrical wiring and not from the network? Don't have everything done yet and have a few other things torn apart so haven't had a chance to test. Thanks Mike.

I recently switched all of my electronics to a dedicated source while the nmea network was still powered by the house/cranking battery and it was not an issue.
