Keysight N6785A Source/Measure Unit for Battery Drain Analysis
The Keysight N6785A is an advanced Source/Measure Unit (SMU) designed specifically for battery drain analysis, providing unparalleled accuracy for both static and dynamic current measurements. Whether you need to measure currents from nanoamperes (nA) to amperes (A), this device is engineered to meet the challenges posed by different operating states of your device under test (DUT), including off, sleep, standby, and transmit modes.
One of its standout features, seamless measurement ranging, allows the N6785A to automatically adapt to changes in current consumption by seamlessly switching to the most precise measurement range available. This capability, combined with its built-in 18-bit digitizers, results in an effective vertical resolution of approximately 28 bits, facilitating insights into power consumption that were previously unattainable.
Features:
- Acquire deep insights into power consumption, enabling optimization for exceptional battery life.
- Concurrent measurement across all modes of operation without the need to manually adjust ranges, ensuring dynamic measurements across a broad current spectrum down to nA and microvolts (μV).
- Emulate battery performance accurately with programmable output resistance.
- Monitor real-world battery applications using the built-in auxiliary voltage measurement system while performing current measurements using the SMU's ammeter mode.
- Comprehend measurements effectively with integrated tools for data logging, statistical analysis, and visualization.
