鳥牌4305A大功率功率計Bird 4305A
· 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.
Accurate CW power measurement over 450 kHz to 2.3 GHz and 50 W to 25 KW
· Uses 4305A and 1-5/8" elements
· Constructed with a 1-5/8” line section for higher power measurements
· Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements
