N6784A 4-Quadrant General-Purpose Source/Measure Unit

The Keysight N6784A Source/Measure Unit (SMU) is a versatile 4-quadrant power module designed for precise sourcing and measurement in R&D and automated test environments. With a voltage range of 0–20 V, a current range of ±3 A, and a maximum power output of 20 W, it serves as both a bipolar power supply and an electronic load. This dual functionality makes it ideal for testing a wide variety of devices under real-world conditions, including characterization, functional testing, and dynamic power emulation.

The N6784A features glitch-free operation, ensuring stability and safety during output and measurement range changes, even when used with devices requiring high capacitance (up to 150 µF). It offers fast transient response times of ≤35 µs and a settling band of ±10 mV, making it suitable for applications that demand rapid, accurate adjustments. High measurement accuracy (±0.025% for voltage and ±0.03% for current) ensures reliable data, while its integration into the Keysight N6700 modular power system allows for seamless compatibility with advanced tools like waveform generation and data logging. Compact and powerful, the N6784A is an essential tool for engineers requiring precision and flexibility in power testing.
