Microtest 6380 LCR Meter

The Microtest 6380 LCR Meter extends the measurement frequency range to 10 MHz while maintaining 0.05% basic accuracy, addressing applications where component behavior at higher frequencies is critical — RF inductor characterization, high-frequency capacitor evaluation, EMI filter impedance profiling, and ferrite material analysis. The 6380 shares the same measurement parameter set, bin sorting capability, and production automation features as the 6370, with the extended frequency range enabling characterization of components operating in MHz-frequency power converters, RF circuits, and high-speed digital systems.

Extended Frequency Applications

Application	Frequency Range	Why Higher Frequency Matters
RF Inductor Characterization	1 - 10 MHz	Self-resonant frequency, parasitic capacitance
High-Frequency Capacitors	1 - 10 MHz	ESR and ESL at operating frequency
EMI Filter Impedance	100 kHz - 10 MHz	Insertion loss across interference spectrum
Ferrite Material Analysis	100 kHz - 10 MHz	Permeability vs. frequency, core loss
High-Speed Decoupling	1 - 10 MHz	Impedance at switching frequency harmonics
Transformer Parasitics	100 kHz - 10 MHz	Leakage inductance, interwinding capacitance

The 6380 is the preferred choice for teams characterizing components that operate at or above 5 MHz — where the 6370’s frequency range ends. Power electronics engineers evaluating GaN and SiC converter magnetics, RF designers qualifying inductors for matching networks, and EMC engineers profiling filter components all benefit from impedance data at the actual operating frequency rather than extrapolating from lower-frequency measurements.

GSAS Micro Systems provides guidance on selecting between the 6370 and 6380 based on application frequency requirements, along with fixture design and handler interface configuration for production deployment.
