the keysight 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.
