Automatic probing system(APS) is a solution for mmWave DIB de-embedding which operates up to 53 GHz, and the purpose of this system is designed to help DIB DIAG application engineers quickly identify RF/Analog-related failures(such as the connectors, cables, switches/relays and PCB traces) at the NPI phase. This scalar version of de-embedding system also provides an efficient and reliable way to remove attenuation of input and output traces from the test fixture and increase fault coverage.

In summary, DIB de-embedding is essential to characterize RF devices accurately. Automatic probing system (APS) is an intuitive solution with plug-in tool in IGXL to assist application engineer to evaluate the impact of the load board on the signal quality and make necessary adjustments or compensations.
