MFITF Impedance Test Fixture

For optimal impedance measurements, we recommend the MFITF Impedance Test Fixture. The MFITF and the carriers are designed to minimize parasitics and damping. However, the MFIA is fully compatible with other commercially available test fixtures with a 22-mm BNC spacing; other impedance setups can also be connected to the front panel. Auxiliary outputs and inputs provide additional control signals from and to the device under test (DUT) or analog feedback with other instrumentation. DIO connectors and trigger ports enable measurements that require precise synchronization of the impedance measurements with other instruments in the setup​.

The MFIA Impedance Analyzer is sold with the MFITF Impedance Test Fixture. The Test Fixture shown below is directly connected to the LCUR, LPOT, HPOT, HCUR connectors on the MFIA front panel. The spacing of the BNC connectors is compatible with established standards for LCR meter and impedance analyzer test fixtures. The MFITF comes with a set of 12 low-capacitive and low-loss DUT carriers for surface-mounted devices (SMD) and for through-hole components. Using the MFIA in combination with the MFITF and the carriers ensures the best possible accuracy.

The MFITF front panel shown above integrates an eight-pin connector (Sullins PPPC081LFBN-RC, Digikey part number S7041-ND) providing four signal contacts and four guard contacts for customized DUT holders.
