Besides its graphical display, the B2980A series offers best-in-class performance, with a 2 pA to 20 mA operating range and an internal 1000 V source, as well as a host of innovative capabilities designed to optimize measurement confidence. It allows measuring currents as low as 0.01 fA (femtoamperes) and resistances as high as 10 PΩ (petaohms).

  • A battery operation mode that eliminates the effect of any AC power noise on measurements and enables detection of previously hidden signals.
  • A time-domain view that makes it easy to capture transient signal effects as well as select the desired measurement data.
  • A real-time histogram display capability for quick statistical analysis of measurement data – a capability previously only available on an external PC. Because the display is continuously updated on a real-time basis, users can quickly debug their measurement environment and setup. This eliminates any ambiguity between the measurement environment and setup and the measurement data.
  • A Test Setup Integrity function and dedicated accessories designed to ensure maximum measurement accuracy. In sensitive measurement applications, setting up the appropriate cabling and equipment connections can be quite difficult. Conventional picoammeters and electrometers fail to address issues related to test setup, such as external cabling. With the B2980A Series’ optional setup integrity checker function, users can now more easily isolate causes of noise.
