美国鸟牌Bird【4305A】大功率功率计,便携式功率表,2.3GHz/2500W
· High-Power Wattmeter
The 4305A Wattmeter is a field-proven portable, insertion-type instrument designed to measure both forward and reflected CW power in coaxial transmission lines under any load condition.
With a fullscale accuracy of ± 5%, it accurately measures RF power with low added VSWR and insertion loss.
QC (quick change) type connectors and a full range of plug-in elements provide a wide choice of frequency ranges and power levels.
