A National RF Power Comparison in Star Type

Recently, 11 laboratories from the provincial and municipal metrology departments and enterprises participated in a microwave power comparison with Type-N connector, which was organized by the National Institute of Metrology (NIM), China. In this comparison, the participating laboratory was required to provide their own power sensor and calibration factors. The power sensors were measured using a reference system at the NIM. This star-type comparison can save a lot time and effort while ensuring the validity and rationality of the comparison results.
