One-Port Reflection Error Correction

One-Port Reflection Error Correction
• removes directivity errors of the test setup
• removes source match errors of the test setup
• removes frequency response of the test setup
You can perform a 1-port correction for an S

NOTE This is the recommended error correction process for all reflection measurements, when full
two-port correction or enhanced response calibration is not used.
