The Agilent N6784A is a source/measure unit (SMU) designed for general-purpose precision sourcing and measurement. General-purpose applications can span many different industries and many different devices under test (DUTs). The N6784A SMU is a versatile tool designed to tackle many of these general-purpose applications. Its glitch-free operation ensures safe usage with the DUT during output and measurement range changes, even with capacitances of up to 150 µF. Its 4-quadrant operation enables it to act as a bipolar power supply or a bipolar electronic load, for added versatility. When using the N6784A SMU, engineers can be confident that they have an all-around general-purpose tool for their test systems or lab bench.

Other features and benefits of the N6784A:

• Glitch-free sourcing and measurement ― change output and measurement ranges without any glitches
• 4-quadrant operation ― perform as a bipolar voltage or current source or as a bipolar CV or CC electronic load
• Four current programming ranges - precisely source current down µA
• Four current measurement ranges ― precisely capture the current levels of the DUT during different modes of operation
• Excellent transient response ― keep voltage or current stable during high-speed load changes
• Fast modulation of DC ― create waveforms up to 100 kHz to stimulate or load down the DUT
• High-speed digitized measurements ― capture/view the power consumption of the DUT up to every 5 µs with built-in 200 kHz digitizer

Other N6700 SMUs:
