The Keysight B2961A is a 6.5-digit single-channel power source delivering precision voltage and current sourcing for characterization of sensitive electronic components. Operating in four-quadrant mode, it sources from 100 nV to ±210 V and 10 fA to ±3.03 A DC, with pulsed current capability to ±10.5 A. Maximum output power reaches 31.8 W. The instrument combines exceptional resolution—down to 100 nV / 10 fA programmable steps—with noise floors as low as 10 μVrms (10 Hz to 20 MHz) and 1 nVrms/√Hz at 10 kHz. Optional ultra-low noise filters enhance performance for noise-critical measurements.
