Good System Hardware Design is the First Step of

Calibration

Make measurement system as clean as possible

• Good frequency response

• Low reflection coefficients (VSWR)

• Good stability

Calibration only as good as hardware stability

Calibration can’t make up for poor system design

This slide was originally created for “Microwave System Design Methodology” training in 1997
