4305A Thruline® 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 full-scale 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
