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 (see figure); other impedance setups can also be connected to its front panel. Auxiliary outputs and inputs provide additional control signals from and to the device under test (DUT) or analog feedback to 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 is directly connected to the MFIA through the LCUR, LPOT, HPOT, and HCUR connectors on the instrument's front panel. 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 (see figure) integrates an 8-pin connector (Sullins PPPC081LFBN-RC, Digikey part number S7041-ND) that provides 4 signal contacts and 4 guard contacts for customized DUT holders.
The following 12 PCB-based carriers are delivered with the MFITF:
Open (1 piece) | Open circuit for compensation and testing |
Short (1 piece) | Short circuit for compensation and testing |
1 kΩ 0.05% (1 piece) | 1 kΩ load with 0.05% accuracy for compensation and testing |
4Pt (4 pieces) | Carrier for SMDs with 4-terminal connection |
2Pt (3 pieces) | Carrier for SMDs with 2-terminal connection |
Through hole (2 pieces) | Carrier for through-hole components |
The MFITF Impedance Test Fixture is designed to measure the impedance of various lead type devices. The MFITF employs Kelvin contacts that ensure a wide impedance measurement range.
