About Us


Our History

Our parent company Tescom, founded in 1982, has been serving the Telecommunications and CATV industries for over 35 years, and manufactures and services a variety of Telecommunications and Timing products.

In 2007, recognizing their customers’ need for quality instrument calibrations, Tescom Calibration began as an ISO17025 accredited electronic and physical/dimensional laboratory, focused on meeting the unique calibration needs of the telecommunications industry.In 2012, Tescom acquired the former Motorola (Freescale) Semiconductor calibration laboratories in Austin, Texas and Tempe, Arizona, and has since, grown to become the leading commercial calibration service provider in the Austin area.

In 2014, Tescom Calibration placed an imbedded lab in a customer facility in San Antonio, Texas; and due to continuing growth we expanded to a permanent facility in 2015.

In 2018, our parent company moved to new corporate headquarters facility in Pflugerville, Texas. As a part of that move, to accommodate our business growth, Tescom Calibration moved into our new, larger home at 2600 Longhorn Boulevard in Austin, Texas.

In 2018 Tescom acquired Siress Enterprises Power Supply Repair. This new division now provides Tescom Calibration with a broadened capability to meet customers repair needs with their ability to repair a wide variety of AC and DC power supplies and sources.
