### ⭐⭐⭐⭐⭐ Does what I want. Easy to read display. Big Learning curve of it's capabilities and limitations.
*by F***R on 28 December 2023*

Takes awhile to find your way thru the menus though they are intuitive. Only scratched the surface of it's capabilities. Will need to purchase or build attenuators to protect it's input.
