Description :

Keysight Technologies B2961A 6.5 Digit Low Noise Power Sources are a new generation of power supply/sources offering best-in-class precision, wide bipolar output ranges and extremely low noise. They also possess graphing capabilities and other innovative features that enable tests and evaluation that conventional power supply/sources cannot do. This makes them ideal companion Products for other instruments such as oscilloscopes, network analysers, spectrum analysers, frequency counters, digital multi meters, nano-voltmeters, etc. The Keysight Technologies B2961A can provide a power supply and source solution that meets the difficult measurement challenges faced by researchers, designers and developers working on advanced components, circuits and materials.

Only source with 6.5 digit resolution and a wide bipolar range of 100 nV - 210 V / 10 fA - 10.5 A. The Keysight Technologies B2961A Power Sources have broad voltage (up to ±210 V) and current (up to ±3 A DC and ±10.5 A pulsed) sourcing ranges and excellent 6.5 digit resolution (minimum 100 nV/10 fA program resolution). This enables you to source voltage from 100 nV to 210 V and current from 10 fA to 3A DC / 10.5 A pulsed in a single box. Unlike a typical power supply/source, they support 4-quardant operation that gives you the freedom to accurately and precisely supply any voltage or current contained within their ranges and power limit (31.8W) regardless of polarity.

Best-in-class noise floor of 10 μVrms (1 nVrms / √Hz@10 kHz) outperforms that of even linear power supplies. Low noise performance is required for the development of noise sensitive applications such as VCOs (voltage controlled oscillators), ADC/DAC, new material evaluation, etc. However, conventional power supplies and sources have not been able to achieve the noise levels to meet these needs. The Keysight Technologies B2961A supports an optional external filter that enables ultra-low noise output down to 10 µVrms and 1nVrms/√Hz (at 10 kHz), which has never before been possible on a low-cost bench-top source.

Quick front-panel debug and verification. The Keysight Technologies B2961A have a 4.3 inch wide LCD display, and all of their capabilities are accessible from the front-panel graphical user interface (GUI). The graphical display not only simplifies user-operation, but it also facilitates viewing measurement results. In addition to their built-in 4.5 digit voltage and current monitoring capability, the Keysight Technologies B2961A can display results in numerical or graphical (V-t / I-t) formats on their screen. This permits quick checking and debugging of measurement results without the need for additional equipment.

Flexible arbitrary waveform generation capabilities provide more flexibility than simple DC. In addition to DC output, the Keysight Technologies B2961A has the ability to generate pulsed, swept and arbitrary waveforms in both voltage and current anywhere within its wide output range. Its arbitrary waveform generation capability supports common waveform types (sine, ramp, square, etc.) in addition to user-defined waveforms. This provides a great deal of versatility and allows the B2961A/B2962A to be used in many complex applications.

The ability to emulate many types of voltage and current characteristics aids device evaluation. The programmable output resistance feature allows you to specify either an output resistance (positive or negative) or a specific voltage vs. current source characteristic. This feature is ideal for emulating a wide variety of devices (such as batteries, photovoltaic cells, sensors, transducers, etc.) that are otherwise difficult to simulate.
