The Keysight (Agilent) 4286A RF LCR Meter delivers high-accuracy impedance measurements in the RF range, using a direct-current voltage-measurement technique instead of conventional reflection methods. Operating at 1 MHz to 1 GHz, it offers precise impedance evaluation over a wide range and advanced calibration for improved Q measurement accuracy—typically 6% at 100 MHz with Q=100. This capability minimizes design uncertainty by providing true device values under RF conditions. Configurable with various test heads, calibration, and standard sets, it supports flexible testing setups.
Ideal for electronic component evaluation, circuit analysis, and RF material testing, the 4286A enhances design confidence and quality control.
