DATA SHEE T B2980A Series Femto/Picoammeter and Electrometer/High Resistance Meter The world’s only graphical Picoammeter/Electrometer that can confidently measure down to 0.
Product Overview Unique capabilities and features maximize confidence for sensitive measurements Keysight B2980A Series of Femto/Picoammeters and Electrometers/High Resistance Meters not only offer best-in-class measurement performance, but also provide unprecedented features to maximize your measurement confidence. The Femto/Picoammeters and Electrometers both offer 0.01 fA (10 -17 A) minimum current resolution, which meets virtually all existing and future low-level current measurement needs.
The World’s Only Graphical Picoammeter/Electrometer that can Confidently Measure Down to 0.01 fA and Up to 10 PΩ 0.01 fA digit Battery Best-in-class 2 pA to 20 mA current measurement ranges and internal 1,000 V sourcing capability ensure accurate 0.
The B2980A series’ unmatched 0.01 fA resolution combines with other unique features to solve previously intractable measurement challenges How fast can the B2980A series capture data? Find us at www.keysight.com Overhead Aperture Overhead Aperture Aperture Aperture All low-level measurements carry with them a degree of statistical uncertainty due to inherent fluctuations in the measurement environment.
In contrast the B2980A’s real-time and auto-scalable histogram display capability continuously updates the mean and sigma, enabling you to debug your measurement setup instantly without the need for any post-measurement data crunching. The histogram can be displayed in the Meter View, allowing you to compare accumulated data on the histogram with real-time numeric data. Note: The maximum number of data points supported by the histogram is 100,000.
Challenge 4: Verifying the integrity of measurement cabling is essential for accurate measurements, but conventional instruments do not offer any means to validate cable performance. How much faster is the B2980A series’ settling time? The B2980A series also has specialized accessories available to facilitate certain types of measurements.
Innovative measurement functions enable both novice and experienced users to utilize all of the B2980A series’ powerful measurement capabilities Selecting the appropriate range and aperture time for low-level measurements is not always straightforward, since these settings are affected by both target device or sample characteristics and measurement conditions (noise, temperature, humidity, etc.). For these reasons, selecting the optimal test settings can be challenging for even experienced users.
Free PC-based software and multiple interface options provide flexible remote control choices Keysight provides two PC-based software control options for the B2980A series: B2900A Quick I/V Measurement Software and a B2900A Graphical Web Interface. Quick I/V software can communicate with the B2980A series via several popular interfaces: LAN, GPIB (up to four B2980A series units) and USB (one B2980A series unit). It provides almost the same functionalities of your B2980A series’ front panel.
