4522, Single Meter - Dual Element Panel Meter

4522, Single Meter/Dual Element and Selector Switch Panel Meter
This series of panel-mounted Wattmeters is 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 4520 series will cover frequencies form 0.45 to 2700 MHz. Measurement accuracy is ±5% of full scale.

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.
