4522, RF Panel Meter with Selector Switch
The 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.
