4410A, Multipower RF Wattmeter

4410A, Portable Multipower RF Wattmeter

4410A Wattmeter uses the basic principles and “look and feel” of the Model 43 Wattmeter but transforms it into a highly accurate high dynamic range instrument. The mirrored-scale linear range meter has 2 switchable ranges, 0-1 and 0-3. Power is read as a multiple of the value indicated by the pointer, the decimal point location depending upon the range switch position and the factor printed on the plug-in element.
