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
The only difference between the two procedures is the measurement parameter that you
select.
NOTE This is the recommended error correction process for all reflection
measurements, when full two-port correction or enhanced response
calibration is not used.
