We make test equipment people love to use.

Our Story

Once upon a time there were two brothers named Mark and Joe who loved EE but didn’t love the tools. One day they decided to do something about that, so they created a logic analyzer with a nice aluminum case and beautiful and easy-to-use software for only $149.

Since then, tens-of-thousands of engineers, students, and hobbyists from all over the world have used Logic. Logic has been used to help with just about everything you can think of: satellites, avionics, submarines, electric cars, and everything in between. We are super excited to be a part of it.

We believe in

  • Simple, beautiful, and powerful products
  • Great customer experiences
  • Craftsmanship
  • Treating people well
  • Loving what we do

What’s Next?

We will be continuing to improve our mixed-signal logic analyzer software so that is as polished, powerful, and easy-to-use as possible.
