The B2901B Precision Source / Measure Unit (SMU) is a 1-channel, compact and cost-effective bench-top SMU to source and measure both voltage and current.


The Keysight B2901B precision source / measure unit (SMU) is a 1-channel, compact, and cost-effective benchtop SMU with the capability to source and measure both voltage and current. It easily measures current versus voltage (I/V) with high accuracy. The 4-quadrant source and measurement capabilities enable taking I/V measurements without configuring multiple instruments.

Measurement capabilities

  • configuration supports one-channel setup
  • minimum source resolution at 1 pA /1 μV, minimum measurement resolution at 100 fA / 100 nV
  • maximum output at 210 V, 3 A DC / 10.5 A pulse
  • waveform generation (arbitrary) and digitizing capabilities from 20 μs interval

Key features

  • measurement capabilities with an integrated 4-quadrant source
  • color 4.3-inch display supports both graphical and numerical view modes
  • application software facilitates PC-based instrument control included at no charge
  • high throughput and SCPI command support conventional SMU’s command set
