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 electrometers feature a 1,000 V voltage sourcing capability that supports up to 10 P (1016 ) resistance measurements. The electrometers also work with Keysight's well-proven high resistance meter accessories. Both the Femto/Picoammeter and Electrometer have battery powered versions to eliminate AC power line noise. This available capability provides an unmatched level of noise reduction, enabling low-level measurements that were previously impossible. Unlike conventional picoammeters and electrometers, the B2980A series possesses a 4.3" color LCDbased graphical user interface (GUI) that provides multiple options for viewing data. In addition to numeric format, data can also be viewed as a graph, as a histogram and as a trend chart. These unique front-panel capabilities facilitate the capture of transient behavior and provide the ability to make quick statistical analyses without the need for a PC. The B2980A series also has features to help you maintain measurement integrity on the external cabling and ixturing. The available Setup Integrity Checker software permits the comparison of noise levels for different cabling and ixturing arrangements, allowing you to identify and isolate the noise-sensitive areas in your measurement system. In addition to these impressive measurement capabilities, the B2980A series has easy-to-use and convenient measurement assist functions that permit users with limited or no electrical engineering training to perform complicated electrical characterization operations with ease.

Since the B2980A series provides a best-in-class 0.01 fA current measurement resolution in both its femto/picoammeter and electrometer versions, it can perform precise and detailed measurements that were previously impossible using conventional picoammeters and electrometers. Therefore, you are assured that your current measurement requirements will be met well into the future. Conventional Picoammeter 1 Why is 0.01 fA resolution important? DMM - 0.01 fA (10 -17 A) minimum measurement resolution and 2 pA to 20 mA current measurement ranges with 6.5 digits resolution - < 20 V burden voltage in its lowest current range - High speed reading rate up to 20,000 rdg/s - Battery operation models for line noise free measurements1 - Built-in 1,000 V voltage source2 - Measurement resistances up to 10 P (1016 )2 - > 200 T input impedance for up to 20 V voltage measurement 2 - Independent current and voltage measurement 2 - Charge measurement down to 2 nC range with 6.5 digits resolution2 - Temperature and humidity measurements2 - Graphical viewing modes (Meter, Graph, Histogram and Roll View) - Easy-to-use auto navigation to select optimal range and aperture - Optional Test Setup Integrity Checker function for noise source isolation - Versatile interface (USB 2.0: LAN, GPIB, LXI Core) - USB (front): store data, save/recall setup information - Free PC control software 04 | Keysight | B2980A Series Femto/Picoammeter and Electrometer/High Resistance Meter - Data Sheet The B2980A series' unmatched 0.01 fA resolution combines with other unique features to solve previously intractable measurement challenges Challenge 1: Instruments that only have numeric displays do not give you any control over when to take data during a transient response. How fast can the B2980A series capture data? RUN RUN RUN RUN When should I take the measurement data? Solution 1: The B2980A series' time domain view (Roll View) lets you visually choose when to capture data. The B2980A series' GUI provides a Roll View that can graphically display data as it is taken and that also can store up to 100,000 of these data points for later retrieval. With a sampling rate of up to 100 kHz, the Roll View can reveal real-time measurement trends and provide valuable insights into the dynamics of your DUT's behavior. To facilitate this data analysis, the B2980A series provides lexible graphing capabilities. In Graph View the electrometers can plot I-V curves on their displays using values from either the internal voltage source or voltage measurement data. In addition, it is easy to generate a variety of other X-Y plots such as I-t, V-t, R-t, Q-t, I-R, etc. (speciic graphical display capabilities depend on product model). These powerful and versatile graphical capabilities allow you to gain valuable insights when making sensitive measurements. Time domain view (Roll View) Measurement speed is usually determined by the aperture time of the integration setting, which is typically proportional to some number of power line cycles (PLCs). Smaller aperture times are obviously more desirable as long as they provide suficient averaging to prevent power line noise from affecting the measurement. However, conventional instruments often cannot capture fast transients due to their relatively slow reading rates that require long overhead after the aperture closes. In contrast, the B2980A series' fast reading rate (20,000 rdg/s) and streamlined system architecture greatly reduce overhead time. As a result the B2980A series does not lose data sampling capability even in its minimum PLC setting, allowing it to capture more detailed DUT responses. The example below compares the data sampling capability of a conventional instrument with that of the B2980A series. As this example shows, the B2980A series can capture data with x4 better timing resolution due to its low measurement overhead. Data recorded up to 100,000 points Overhead Aperture Overhead Aperture Aperture Overhead Aperture Aperture Keysight B2980A series Aperture Aperture Aperture Aperture Aperture Aperture Aperture All low-level measurements carry with them a degree of statistical uncertainty due to inherent luctuations in the measurement environment. The conventional method to deal with this issue involves post-measurement evaluation of the data (usually on a PC) using a histogram. However, this process can become tedious if you need to perform several measurement and test setup debug cycles. Conventional instrument Aperture Solution 2: You can instantly view and evaluate data distributions using the real-time histogram feature Measured level How does the measurement result distribute? Measured level Challenge 2: Instruments with only numeric displays often exhibit instability in their least signiicant digits and offer no information about the measurement's mean and standard deviation. Measured level Original waveform 05 | Keysight | B2980A Series Femto/Picoammeter and Electrometer/High Resistance Meter - Data Sheet 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. 100 BINS Histogram View 40 BINS On Meter View 20 BINS How much lower is the B2980A series' noise loor? Even when operating in AC mode with 0.1 PLC integration time, the B2980A series' advanced design provides current measurement performance that is much better than conventional picoammeters and electrometers. The graph shown below compares current measurement noise levels under identical measurement conditions. As can be seen the B2980A series can make both lower noise and faster measurements, which reduces the trade-offs that normally need to be made between these two goals. Normalized 2 nA range RMS noise 10 BINS 0.1 PLC, 3 m triaxial cable 18 Normalized RMS noise Challenge 3: Eliminating noise from low-level measurements is dificult and often requires extensive measurement expertise. 14 12 10 8 6 4 2 0 B2980A Solution 3: The B2980A series' battery operated models eliminate power line noise and enhance low noise measurement performance. AC power line noise strongly impacts sensitive measurements. While integrating over one or more PLCs can minimize AC power line noise effects, even the B2980A's excellent noise performance cannot eliminate 100% of this noise unless the instrument is completely isolated. Therefore, both the Femto/Picoammeter and Electrometer have available battery operated versions that enable you to make power-line-noise-free measurements. The two battery models can function for 7 hours (B2983A) or 5 hours (B2987A) under normal operating conditions, and they also automatically save your measured data and measurement setup information if the battery level goes below 5%. Of course, besides eliminating noise the battery models provide the added beneit of portability allowing you to use them anywhere you want.

Triaxial cables, which are available from a variety of sources, are required for low-current measurement applications. Keysight triaxial cables employ a semiconductor layer between the insulator and inner jacket, which minimizes the triboelectricity generated by friction at these boundaries. The net result is that Keysight triaxial cables are largely unaffected by cable vibration, which enables more accurate and stable measurements. All B2980A products come with a 1.5 meter version of this triaxial cable. 06 | Keysight | B2980A Series Femto/Picoammeter and Electrometer/High Resistance Meter - Data Sheet 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? When performing sensitive measurements making appropriate cabling connections is often one of the more dificult challenges. Many factors can contribute to measurement noise or instability, including incorrect cabling, poor cable quality and improper guarding; however, determining the root cause of a measurement ixturing issue from among all of these factors is not easy. Conventional instruments do not provide any help to solve these types of issues and they typically only offer written guidance on best practices. In contrast, the B2980A series has an available Setup Integrity Checker function that can identify noise caused by external elements (cables, adapters, shields, chambers, etc.) and display the information in tabular format on the front-panel GUI. As shown below, the setup integrity checker function allows you to compare the noise level of the instrument with no cables connected against the noise level with different setup elements connected. By comparing the noise level standard deviation of different setup elements side by side, you can easily determine the quality of cables and other setup elements necessary for your measurements. 0.1 % of final value Final value Measured data Solution 4: Optional software and dedicated accessories help mitigate cabling complexities When comparing instrument settling times, you need to understand how each instrument deines this speciication. Most conventional instruments deine settling time as the time it takes to reach 10% of the inal value, whereas the B2980A series uses a value of 0.1%. By reducing dielectric absorption (DA), the B2980A achieves a faster settling time using the 0.1% limit even in its lower measurement ranges as shown below. The B2980A series also has specialized accessories available to facilitate certain types of measurements. For example, the N1413A High Resistance Meter Fixture Adapter allows you to use the B2980A series with Keysight's accessories for high resistance measurement (such as the 16008B Resistivity Cell). A High Resistance Measurement Universal Adapter (N1414A) is also available to simplify the cabling for high resistance measurements.

Measurement assist functions reduce low-level measurement challenges 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. However, the B2980A series has a variety of assist functions to improve your measurement productivity. The navigation keys enable you to easily ind the optimal measurement range and aperture time (speed) parameters. The column at the right shows how the navigation keys work. - Pressing the Home key automatically sets the most appropriate range and speed at any time Measurement range High + Current Voltage Resistance Charge Measurement Measurement Measurement Measurement 20 mA 20 V 1P 2 C 2 mA 2V 100 T 200 nC 200 A 10 T 20 nC 20 A 1T 2 nC 2 A 100 G 200 nA 10 G 20 nA 1G 2 nA 100 M 200 pA 10 M 20 pA 1M 2 pA Coarse Coarse Stable Normal Quick Fine Fine Aperture time (Integration time) Long How does the Navigation feature work? The B2980A series possesses an innovative measurement navigation capability that helps users optimize both aperture time and measurement range. As shown below, it has three pre-programmed range vs. aperture curves that cover most logical combinations. By default measurements start using the "Normal" curve and an appropriate measurement range. However, if the measured data seems noisy then pressing the "Fine Res" key switches the settings over to the "Stable" curve. This will automatically adjust the settings to a longer aperture time and reduce the noise. In addition, if you need to make a rough measurement quickly then switching over to the "Quick" curve will save measurement time. The Navigation feature's pre-deined curves enable even novice engineers and researchers to make low-level measurements quickly without any need to struggle over selecting the appropriate aperture time and range settings. Of course, experienced users can override these curves and use the instrument in purely manual mode if a particular measurement requires customized settings. The "Save" and "Recall" keys located below the rotary knob enable you to instantly save and recall all test setup parameters to/from one of five available storage buffers. Measurement range High The "Save" and "Recall" keys ensure that you never lose setup parameters obtained through prolonged trial-and-error.

PC connected via GPIB, LAN or USB Keysight B2900A Quick IV Measurement Software What are the B2980A series' temperature and humidity measurement capabilities? Temperature and humidity are critical parameters for high resistance measurements. The B2985A and B2987A electrometers contain both temperature and humidity sensor interfaces, and a dedicated thermocouple (N1423A) is furnished with these models. The EE07 Digital Humidity/Temperature Probe from E+E Electronik can be used for humidity and temperature sensing, which provides more accurate temperature data than a thermocouple For more information Please visit the product web pages containing demo videos, application information, sample programs, etc. from: www.keysight.com/ind/b2980a Keysight B2980A Graphical Web Interface B2980A series Femto/Picoammeter Electrometer Ready-to-use instrument drivers simplify programming For users that want to create their own customized software, IVI-C and IVI-COM drivers for the B2980A series are available.
