Equipped with USB, GPIB, and LAN interfaces, model 891 can measure inductance, capacitance, and DC resistance with 0.05% best impedance accuracy over fully adjustable test frequency range of 20 Hz to 300 kHz. Selectable test levels include 0.5 and 1 Vrms, and such features as 300-point linear and logarithmic sweep function, bin comparator, and remote control interfaces make this unit suited for characterizing components in lab, QC, and small volume production environments.
