World's only source with 6.5 digit resolution and a wide bipolar range of 100 nV - 210 V / 10 fA - 10.5 A
The Keysight B2961A/B2962A 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 B2961A/B2962A 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.
