4522, RF Panel Meter with Selector Switch
Bird 4522 Single Meter, Dual Element with Selector Switch Panel Mount Wattmeter is designed for power measurement in CW and FM systems that employ 50-Ohm cable or 7/8" EIA transmission lines. The single-meter 4522 has two element sockets. The second socket permits the use of a more sensitive element to measure reflected power and accurately determine VSWR.
A selector switch changes the display between forward and reflected power. 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 selected , the 4520 series will cover frequencies form 0.45 to 2700 MHz. Measurement accuracy is +/- 5% of full scale.
