Impressive 6.5 Digit 100 nV/10 fA Resolution, 10 μVrms Ultra Low Noise and Innovative Source Functions Accelerate Your Research and Development Revolutionary power supply/source meets both existing and future test needs Power supplies/sources are essential instruments for test and evaluation across the electronics industry. The on-going industry trends of reduced power consumption and faster communication data rates increasingly require power sources that can support lower levels of current and voltage.
Key Features and Benefits Key Features Benefit Best-in-class resolution and wide bipolar range –– 6.5 digit (100 nV/10 fA resolution) –– 210 V & 3 A (DC)/10.5 A (pulsed) ranges –– 4-quadrant operation Very precise test and evaluation can be performed within a wide 4-quadrant voltage and current range. External ultra low noise filter (option) –– 10 μVrms (10 Hz – 20 MHz) Reveal more of the true characteristics of your noise-sensitive devices and samples than ever before.
Superior Resolution and Wide Bipolar Ranges Meet your Most Challenging Test and Evaluation Needs 6.5 digit resolution enables precise analog-to-digital converter evaluation One area where power supply sourcing resolution is important is analog-to-digital converter (ADC) evaluation. For an 8-bit ADC, a 1 V (peak to peak) signal would have a minimum step voltage of 3.9 mV. In this case a power source with 4.5 digit resolution is sufficient to use for the DC input voltage.
Best-in-Class Noise Performance (10 μVrms) Unlocks the True Characteristics of Your Devices and Samples Three optional filters available for different test needs For applications requiring ultra-low noise performance, the Keysight B2961A/B2962A supports three external filter options. This provides you with the flexibility to select the noise filter price/performance point that best meets your needs.
Intuitive Front-Panel GUI and Wide 4.3” Color LCD Maximize Test and Debug Efficiency Many power supplies and sources only possess a numerical display or a very basic dot matrix display, which are only effective at showing DC values. In contrast, the Keysight B2961A/B2962A has an easy-to-use front panel GUI and a wide 4.3” color LCD. These make it easy to set up sourcing parameters and to display complex current and voltage waveforms.
GUI Based Intuitive Front Panel Design with Rich Standard Interfaces for Your Bench-Top Needs In addition to the graphical user interface and easy-to-use front panel, the Keysight B2961A/B2962A integrates standard interfaces such as USB 2.0, LAN (LXI class C compliant), digital I/O and GPIB in a bench-top instrument form. The optional filters are well designed for the B2961A/B2962A and easy to attach and detach to/from front/rear channels. USB 2.0 for memory I/O 4.
Flexible Source Functions Beyond a DC Instrument Remove Your Test Restrictions Pre-defined and arbitrary waveforms increase your test and evaluation flexibility The Keysight B2961A/B2962A features full-fledged test and evaluation beyond conventional static DC testing. The pre-defined waveform generation capability provides six waveforms: sinusoidal, exponential, ramp, triangle, square and trapezoidal.
Programmable Output Resistance and DC Voltage/Current Output Emulation Capabilities Solve Real-World Measurement Challenges The B2961A/B2962A’s programmable output resistance function provides flexible measurement capabilities The Keysight B2961A/B2962A has a programmable output resistance feature that allows you to control the output behavior of the power source. It supports two test modes, constant and V/I emulation, to provide maximum flexibility and versatility.
Multiple Communication Methods and Software Provide Flexible and Convenient Remote Control Options BenchVue Quick I/V Measurement Software BenchVue allows you to control the B2961A/B2962A as voltage/ current sources from a PC without the need to do any programming. In addition, because BenchVue supports a wide variety of Keysight instruments (oscilloscopes, meters, etc.) it is a good choice when you need to integrate together many different types of instruments on a benchtop.
