FormFactor - Cascade Impedance Standard Substrates for ACP, Infinity, and FPC Probes

Impedance Standard Substrates (ISSs) supports all of your high-frequency probing applications. Using them ensures greater accuracy and better repeatability in on-wafer calibration of vector network analyzers. Our ISSs offer the proven accuracy of LRRM calibrations with automatic load inductance compensation.
