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

### ⭐⭐⭐⭐⭐ Good value
*by L***E on March 12, 2024*

This spectrum analyzer is very sensitive and has a max input of five volts. It takes a lot of exploration to figure out how it works. There is little information in the user’s manual so it is necessary to go to the internet for help. There is no one you can call for help.
