Signal Generators

Signal Generators

TestEquipmentUSA’s range of signal generator kits are perfect complements to your designing, testing, troubleshooting, and repairing operations. In high-stakes environments where precision, accuracy, and safety are paramount, an effective test bench is critical to ensuring proper equipment function before deploying them to the field. Our function generator kit selection includes 7-range 4-in-1 sweep generators, with various frequency outputs, so you can customize your selection to fit the job at hand.

These signal generators are designed to optimize commercial and industrial test benches and are built to high standards of precision and reliability. Compare the specific model number of each unit to select a signal generator kit compatible with your testing environment.

Calibrated Signal & Function Generator Kits

Maintain calibrated signal generator kits with accredited calibration data through our partner service, Gulf Coast Calibration. It’s exceptionally important to generate accurate signals for the purpose of testing other equipment you work with. An ill-calibrated signal generator can cause other tested equipment to return inaccurate results. Ensure your equipment is always covered by sourcing your signal generators from TestEquipmentUSA.

Technical Support

Not sure what you need? Contact us today and our specialists will happily assist you in determining the best signal generator kit for your project. Our specialists are also available to consult with regarding proper equipment use and maintenance. If we don’t carry a product or component that you need, please contact one of our specialists know and we will do our absolute best to find it for you.
