Measurement Range

  • Wide impedance measurement range from 200 m ohm to 3 k ohm

Basic Accuracy

  • 1% basic accuracy

More Features

  • Superior measurement repeatability at low test signal level
  • High-speed measurements: 9 ms


Note: The E4982A LCR Meter, 1 MHz to 3 GHz is the successor of the 4286A/4287A

The 4287A RF LCR meter offers accurate, reliable and fast measurements from 1 MHz to 3 GHz to improve quality and throughput of electronic component testing in production lines. The 4287A employs the direct-current voltage-measurement technique, as opposed to the reflection-measurement technique, which yields accurate measurements over a wide impedance range.
