Keysight N6782A: Precision Source Measure Unit for Functional Testing

Keysight N6782A – Two Quadrant SMU Module for Functional Tests (20W).

The Keysight N6782A Two-Quadrant Source/Measure Unit (SMU) is engineered to provide exceptional precision and versatility for functional testing of electronic devices, including DC/DC converters, power management units, power amplifiers, and embedded system circuits. Designed for seamless integration with the Keysight N6700 Low-Profile Modular Power System or the N6705 DC Power Analyzer, this single-slot 20 W module supports both source and sink (2-quadrant) operation, allowing complete control over device input and output behavior.

Delivering up to 20 V or ±3 A, the N6782A offers high-speed modulation up to 100 kHz, fast transient response, and low noise performance. Its advanced source and measurement capabilities enable engineers to simulate real-world power conditions, characterize DUT behavior, and validate energy efficiency in R&D and automated test environments.

With its integrated measurement accuracy, programmable ranges, and wide dynamic response, the N6782A ensures consistent performance across a variety of applications where precision power sourcing and load emulation are critical.
