The 4263B LCR meter is Agilent Technologies' most cost-effective low-end LCR meter, designed for both component evaluation on the production line and fundamental impedance testing for benchtop applications. In addition to fundamental impedance measurements at test frequency of 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz (20 kHz with option 002), the 4263B provides convenient transformer measurement with option 001.
