4526, Panel-Mount RF Wattmeter
The Bird 4526 Dual Meter, Dual Element Panel Mount Wattmeter is a dual-meter, two element socket unit. The second socket permits the use of a more sensitive element to measure reflected power and accurately determine VSWR. The dual meter configuration simultaneously displays forward and reflected power. It's designed for power measurement in CW and FM systems that employ 50-Ohm cable or 7/8" EIA transmission lines.
All models include a precision line section and either one or two 3-scale analog which give full-scale direct readings from 100 mW to 10 kW. The rack panel fits standard 19-inch equipment racks. Plug-In Elements, the same used in the Bird model 43, are sold separately. Depending on the element slected , the 4526 will cover frequencies form 0.45 to 2700 MHz. Measurement accuracy is +/- 5% of full scale.
