Keysight Technologies

In response to customer demand for replacements for the discontinued 4339B High Resistance Meter and accessories, Keysight recently released these new B2985A/87A accessories:

  • N1424A/B/C Resistivity Cell
  • N1425A/B Low Noise Test Leads and attachments (the N1426A/B/C)
  • N1427A/B Low Noise Test Cables
  • N1428A Component Test Fixture.

The B2985A Electrometer/High Resistance Meter is the world’s only graphical electrometer that allows you to confidently measures small currents with 0.01 fA (0.01 x 10-15 A) resolution and large resistances of up to 10 PΩ (10 x 1015 Ω). The B2985A/87A has advantages over the 4339B such as better graphical user interface, lower noise operation and faster measurement speed. These accessories enhance the B2985A/87A application coverage including material surface/volume resistivity measurements in film or sheet formats, component insulation tests, and more.

The B2985A/87A’s Advantages over the 4339A/B

  1. It is easy to use and analyze.
    • Useful 4 View Modes:
      • Enable users to check data easily
      • Facilitate quick debug and analysis

2. Lower Noise Operation

  • Advanced design achieves low noise measurements!
    • Equal/lower noise than 4339B
      (200 pA to 200 nA Ranges)
    • Reveal data which 4339B cannot show
      (2 pA to 20 pA Ranges)

3.  Faster Measurement Speed

  • 2x faster evaluation time for high resistance material!!
    • 4339B: Fixed (Short, Medium, Long)
    • B2980A: Flexible (10 μs to 2 s)
