Test Equipment Plus was started in 1996 with the idea of providing quality used test equipment at affordable prices. In 2009, we decided to design a compact, lightweight, and inexpensive spectrum analyzer. The goal was to provide a spectrum analyzer with a better price-performance ratio than anything else on the market. The Signal Hound USB Spectrum Analyzer was developed and today there are 5 models ranging in frequencies from 10 Hz to 12.4 GHz. Available with USB 3.0 or 2.0 these spectrum analyzers are ideal for streaming digitized RF bandwidth to your PC or Laptop.
