Tektronix AFG3021B

This Tektronix AFG3021B is a used single-channel arbitrary function generator that provides flexible waveform generation for benchtop testing and design validation work. It can output standard waveforms such as sine, square, and pulse signals alongside arbitrary waveforms built from user-defined data, giving engineers a versatile signal source for a wide array of test scenarios. Its straightforward front panel and menu system make it a practical instrument for both quick calibration tasks and more involved signal generation projects. Engineers and technicians typically use function generators like this AFG3021B for testing analog and digital circuits, simulating sensor outputs, driving components under test, and verifying receiver or amplifier performance. The ability to create custom arbitrary waveforms extends its usefulness beyond basic signal generation into more specialized R&D and troubleshooting applications. Its single-channel design keeps the unit compact while still delivering dependable signal quality for general lab use. This unit is offered in used condition, having previously served in an active test or engineering environment, and it operates in line with its original design intent. It provides a budget-friendly option for labs, schools, and repair shops that need a capable waveform generator without the expense of new equipment. Buyers should expect normal cosmetic wear from prior use and are encouraged to confirm calibration before deploying it in precision-critical applications.
