Full Two-Port Error-Correction Procedure
Load Match (E and E )
LF LR
Description Load match is a measure of the impedance match of the test port that
terminates the output of a 2-port device. Load match error terms are characterized by
measuring the reflection (S11, S22) responses of a "through" configuration during the
calibration procedure.
Significant System Components
• "through" cable
• cable connectors
• test port connectors
Affected Measurements All transmission and reflection measurements of a low
insertion loss two-port devices are most affected by load match errors. Transmission
measurements of lossy devices are also affected.
