The Insertion VSWR specification for the 4480 Wattmeter varies depending on the connector type and the measurement scenario. The 1.05:1.00 VSWR listed on Page 1 of the manual refers to the performance achievable with an N-type connector, which is known for its reliable low-VSWR performance within the specified frequency range. On the other hand, the 1.20:1.00 VSWR found in the specifications on Page 14 represents the maximum or worst-case VSWR across the range of available Quick Connect (QC) connector options. This value accounts for the performance variations among different connector types, but in general, users can expect to see an insertion VSWR around 1.10:1.00 under most conditions.
