Specialized devices for a specialized industry.

All Signal Hound devices are not created equal, and we did this for a reason.

When we started Signal Hound, we didn’t want to create yet another spectrum analyzer that does more than you need for too much money. Instead, we decided that we would provide powerful tools that do exactly what you want, at a price you won’t believe.

Check out the chart below for a device vs. device feature comparison. We tried to be as thorough as possible, but in case we missed something, don’t hesitate to contact us for more information, or post a question on our forums.
