*Supports Seamless Measurement Ranging
The Keysight N6781A is a source/measure unit (SMU) designed specifically for the task of battery drain analysis. Whether the device-under-test (DUT) is an e-Book reader, MP3 player, mobile phone, or pacemaker, the N6781A’s seamless measurement ranging, programmable output resistance, and auxiliary DVM combine to be the best set of advanced features on the market for battery drain analysis. When used with the 14585A Control and Analysis software, the N6781A becomes an even more powerful battery drain analysis solution, offering additional insights into your measurements.
*Keysight patented feature: Seamless Measurement Ranging
Seamless measurement ranging eliminates the challenges of measuring dynamic currents. With seamless measurement ranging, engineers can precisely measure dynamic currents without any glitches or disruptions to the measurement. As the current drawn by the DUT changes, the SMU automatically and instantaneously detects which current measurement ranges will return the most precise measurement and changes to that range seamlessly. When combined with the SMU´s built-in 18-bit digitizer, seamless measurement ranging enables unprecedented effective vertical resolution of 28-bits. This provides unrivaled productivity gains and insights into power consumption by enabling engineers to see the complete current waveform they have never seen before, from nA to A, in one pass and one picture.
Other features and benefits of the N6781A:
- Glitch-free sourcing and measurement - change output and measurement ranges without any glitches
- 2-quadrant operation - perform as a voltage or current source or as a CV or CC electronic load
- 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

What are the differences between Keysight Used & Keysight Premium Used?
You will find more information about the differences of Keysight's used equipment standards here.
Can I configure a unit to meet my personal needs?
Customization is generally possible with our Keysight Premium Used equipment. The majority of our Keysight Premium Used equipment can be configured just the way you need it. Options can be added at additional cost.
Customizing Keysight Premium Used equipment might change the delivery and lead time of the item.
Some Keysight Used products cannot be customized. Use the contact option on the product page to check with the our eStore team.
What accessories are included?
Keysight Premium Used equipment typically comes with the same accessories and warranty as new products.
For Keysight Used products, the accessories included are mentioned in each listing on the Keysight Store on eBay or the Keysight Alibaba store.
Can you include other accessories?
We currently only offer those accessories which are part of the listing. Other accessories can be purchased separately at extra cost with your purchase of a Keysight Used or Keysight Premium Used unit.
Please mention in the comment field which additional accessories or support you are interested in.
For seperate or post-purchase ordering, please contact your local Keysight office or Keysight Partner.
