Unknown Thru – Agilent’s Secret Weapon!
“Unknown Thru” (aka SOLR) algorithm is useful for
both insertable and non-insertable calibrations
Traditional non-insertable methods:
• Swap equal adapters
• Use characterized thru (S-parameters known)
• Perform adapter removal cal
• Add adapters after cal, then, during measurement…
– use port extensions
– de-embed adapters (S-parameters known)
