About Us


Core Technology Group was founded to provide affordable and accurate, test and measurement instruments that help engineers get answers that they need quickly and efficiently.  Our engineering services offer additional resources to your design effort to get your products to market on time.

Our first product, the "Circuit Sleuth" frequency response and impedance analyzer uses patented technology, and was originally created as a tool for in-house design, and characterization of feedback control systems, circuits and components.  It was quickly realized that a low cost, accurate, frequency response analyzer was needed to make this capability available to all engineers.

Core Technology Group's headquarters and manufacturing facility is located about 20 miles north of Philadelphia in the suburb of Chalfont, PA.

Looking ahead, listening to our customers, addressing their needs and responding to changes in the industry, Core Technology Group is exploring opportunities to create new products that further reduce the cost of test and measurement and enable designers to create high quality, reliable products.
