B2961A Agilent Keysight HP BiPolar Power Supply

The B2961A is a 31.8 W, 210 V, 10.5 A bipolar power supply that is also a 6.5 Digit Low Noise Power Source from Agilent Keysight HP.


  • 6.5 digit 1-channel, wide and bipolar voltage/current sourcing (100 nV - 210 V / 10 fA - 10.5 A, 31.8W)
  • Best-in-class noise performance (10 µVrms, 1nVrms/√Hz) with external filter
  • Precision arbitrary waveform capability with support for seven built-in functions and user defined waveforms (1 mHz - 10 kHz)

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.
