The U2761A USB function generator will be discontinued on June 1, 2024. The last day to place an order for this product is May 31, 2024. Keysight will continue to provide support for this product for the standard period of 5 years. You may purchase the relevant bench or modular system as an alternatives  Function Generator (EDU33211A), SMU (N6784A), Digital Multimeter (EDU34450A), Oscilloscope (EDUX1052G), DAQ (DAQ970A).


The U2761A is a 20 MHz function generator that offers 10 standard waveforms plus pulse and arbitrary waveforms generation capabilities. It uses a standard high-speed USB 2.0 interface that provides ease of connectivity ─ allowing users to set up and configure tests swiftly with the plug and play feature.

The U2761A can function as a standalone module or as a modular device in the U2781A USB Product Chassis, providing expansion capabilities and a compact solution when used with the other modules in the USB Modular Instruments and DAQ family.

Keysight U2700A series USB Modular Instruments has won Design News’ Golden Mousetrap Award in the 2009 Best Products Category. The Design News’ Awards Program has recognized engineering innovation and creativity in product design for more than two decades.
