The MICROTEST 9332 is engineered for the electrical characteristic testing of circuit boards that utilize copper foil etching to create coil circuits. It accommodates multiple coil circuits on multi-layered boards with its 64 testing channels, allowing for the simultaneous testing of 32 coil sets. Parameters measured include inductance, impedance, AC and DC resistance, Q value, and other parameters, across a frequency range of 10Hz to 200kHz. The system supports PC connectivity for remote programming and data storage and can be integrated into specialized PCB testing equipment for fully or semi-automatic testing.
