Signal Hound’s Evolving Business Model

The Signal Hound® company started as Test Equipment Plus (TEP) in 1996 with the belief that providing quality used test equipment, at affordable prices to every customer, would drive growth and foster loyal customers. It did. Then in 2006, TEP expanded their focus by designing and manufacturing a color LCD display retrofit kit to answer the need for CRTs that were no longer available for the aging HP® 8566A, 8566B, 8568A, and 8568B spectrum analyzers. TEP also began offering a repair service for HP/Agilent® step attenuators. In 2007 TEP designed and began manufacturing another color LCD display retrofit kit to support the HP/Agilent 8560 series spectrum analyzers. At the same time, TEP also decided to play to their strengths, and began offering test equipment repair services, focusing only on Agilent spectrum analyzers, network analyzers, and signal generators.

During this same time, TEP designed and built their own 5dB 50GHz step attenuator die to ensure ongoing repair capability for Agilent 50GHz step attenuators. They also designed and produced, contracted a semiconductor foundry to run a wafer, TEP’s own 7 GHz 1 watt GaAs amplifier die, the TEP519B. The TEP519B die is still the only MMIC available to keep a particular line of popular microwave signal generators viable for ongoing repair and support. The repair segment of TEP, even though it is small by choice, is now recognized in the RF and microwave test equipment repair industry as a world class operation.

The LCD kits were so well received that in 2009, TEP decided to design a compact, lightweight, and inexpensive spectrum analyzer. The goal was to provide an economical spectrum analyzer with unparalleled value compared to anything else on the market. TEP achieved that goal with the USB-SA44 spectrum analyzer which was introduced in February 2010, marking the birth of the Signal Hound line of test equipment.

Signal Hound’s latest innovation – the Signal Hound SM200A – introduced in early 2018, is a 100 kHz to 20 GHz spectrum analyzer with 1 THz sweep speeds and 110 dB of dynamic range. It’s a perfect device for spectrum monitoring or general benchtop RF analysis, and includes powerful spectrum analyzer software and a comprehensive and flexible API for developing your own applications.

Our Name Changed

TEP continued marketing the Signal Hound line of test equipment as a brand, until April 2014, when they began doing business as Signal Hound. This established Signal Hound not just as a brand name, but also as a company.

The Test Equipment Plus side of the business still provides repair services and LCD display retrofit kits for Agilent/HP test equipment. Visit TEP at their original website, www.testequipmentplus.com.
