The VectorStar ME7838G is a broadband system providing coverage to 220 GHz. Performing power calibrations across the entire sweep range will require multiple sensors and multiple adapters. After the power calibration and de-embedding of the adapters, the reference plane needs to be positioned at the tip of the probe for optimum performance. Relocation of the reference plane requires embedding of the probe using the .s2p file. This application note describes how to update the .s2p file of the probe as wear of the probe becomes a concern.
