功率計簡介： High-Power Wattmeter
The 4305A Wattmeter is a field-proven portable, insertion-te instrument designed to measure both forward and refleed CW power in coaxial tranission lines under any load condition. With a full-scale accuracy of &plun; 5%, it accurately measures RF power with low added VSWR and insertion loss. QC (quick change) te conneors and a full range of plug-in elements provide a wide choice of frequency ranges and power levels.
