4305A型功率计
Portable, High-Power Wattmeter
- Accurate CW power measurement over 450 kHz to 2.3 GHz and 50 W to 25 KW.
- Uses industry standard Bird 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 criticalmeasurements.
The BirdModel 4305 Directional Wattmeter is a field-proven portable,insertion-type instrument designed to measure both forward andreflected CW power in coaxial transmission lines under any loadcondition. With a full-scale accuracy of ± 5%, it accuratelymeasures RF power with low added VSWR and insertion loss. QC (quickchange) type connectors and a full range of plug-in elementsprovide a wide choice of frequency ranges and power levels.
