The Keysight (formerly Agilent) 4287A is an RF LCR meter designed for accurate, reliable, and fast measurements of electronic components in production line environments. Operating over a frequency range of 1 MHz to 3 GHz, it utilizes a direct current-voltage (RF I-V) measurement technique rather than a reflection-measurement technique. This approach yields accurate results over a wide impedance measurement range (200 mΩ to 3 kΩ) and superior repeatability at low test signal levels.
