Compromises of Traditional Methods
Swap equal adapters
• Need phase matched adapters of different sexes (e.g., f-f, m-f)
• Error results from loss and mismatch differences of adapters
Use characterized thru
• Multi-step process
• Need a non-insertable cal to measure S-parameters of characterized thru
Perform adapter removal cal
• Accurate but many steps in calibration (two 2-port calibrations)
Add adapters after cal, then, during measurement…
• Use port extensions – doesn’t remove adapter mismatch effects
• De-embed adapters (S-parameters known) – similar to characterized thru

Non-Insertable ECal Modules
ECal resolves many, but not all non-insertable situations
