The HP/Agilent 4286A RF LCR Meter measures impedance parameters across 1 MHz to 1 GHz with 1% basic accuracy. It employs direct-current voltage-measurement technique (RF I-V method) rather than reflection measurement, delivering superior accuracy across a wide impedance spectrum—particularly for RF inductors in the nH range and high-Q components. The instrument achieves measurement speeds as fast as 15 ms and typical Q accuracy of 6% at 100 MHz for Q = 100, supported by advanced calibration techniques.
