Keysight / Agilent N6781A Source / Measurement Unit, 20 V, +/-1 A or 6 V, +/-3 A, 20 W

The Keysight N6781A Source/Measure Unit (SMU) is engineered for advanced battery drain analysis across a wide range of devices including e-Book readers, MP3 players, mobile phones, and even medical devices like pacemakers. This sophisticated instrument not only offers seamless measurement ranging and programmable output resistance but also comes equipped with an auxiliary digital voltmeter (DVM), making it a top-tier solution for battery testing and analysis.

When paired with the 14585A Control and Analysis software, the Keysight N6781A transforms into an even more comprehensive tool, providing deeper insights into your measurements. Below are key features and specifications that highlight its exceptional capabilities:

Key Features:

• Glitch-free sourcing and measurement ensure output and measurement ranges can be altered without interruptions.
• 2-quadrant operation allows for versatility as a voltage or current source, or as a constant voltage (CV) or constant current (CC) electronic load.
• Four distinct current measurement ranges allow for accurate capture of current levels during varying operational modes of the device-under-test (DUT).
• Excellent transient response maintains stable voltage or current during high-speed load changes, vital for accurate analysis.
• Fast modulation of DC enables the creation of waveforms up to 100 kHz, making it ideal for stimulating or loading down the DUT.
• High-speed digitized measurements with a built-in 200 kHz digitizer capture the DUT's power consumption every 5 µs.
