Core Technology Group is dedicated to providing high quality test equiptment at an affordable price. All of our products are made in the United States and each of our units is hand calibrated before shipment to ensure quality and accuracy.

The Core Technology Group, Circuit Sleuth RA and SA-Series 01, 10 & 40 are full featured Frequency Response / Network / Impedance Analyzers. Combining the latest in high performance DSP technology, highly efficient and elegant design and intuitive, yet powerful Windows compatible control and reporting software, the analyzers enables quick, accurate and cost effective testing of a multitude of electronic circuits. Typical applications include filters, motor controllers, audio amplifiers, RF amplifiers, power supplies - any circuit where it is important to characterize frequency response.

General purpose signal amplifiers featuring isolation, high input impedance, and high output capability. Perfect for driving low input impedance instruments.

The Circuit Sleuth API Tool Kit routines offer an alternative solution for users who prefer writing or need to write their own control programs.

The XA-40 transformer provides complete isolation from the signal source, making it easy to inject test signals into the device under test. Ideal for control system measurements and Bode plots.

We offer a variety of accessories for our analyzers. We carry probes, power supplies, cables, terminators, and even a carrying case. Feel free to browse our selection.
