Multipower, ±5% Reading Accuracy The Model 4412A uses the basic principles and “look and feel” of the Model 43 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. Power ranges covered by individual elements are 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 KW and 2 W to 10 KW, full scale. For most elements, accuracy is +/-5% anywhere above 20% of full scale. The circuitry operates from a rechargeable battery. Temperature-compensated accurate CW and FM power measurements from 200 kHz to 2.3 GHz and 2 mW to 10 KW · Uses special 4410-series wide-range elements · Wide-range accuracy over a 37 dB dynamic range · Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements Power Range | 2 mW - 10 W, 20 mW - 100 W, 200 mW - 1 kW or 2 W - 10 kW full scale in one single Plug-in Element | Frequency Range | 200 kHz-2.3 GHz CW or FM | Insertion VSWR | N Connectors 1.25 max. to 2300 MHz | Connectors | QC Type (Female N normally supplied) | Ambient Temp Range [°C (°F)] | To 120% of nominal full scale (i.e.12 W, 120 W, 1200 W, or 12,000 W). No damage or degradation to the unit will result, regardless of the Range Selector Switch position. | Finish | Gray Powder Coat | Nominal Size [inches (mm)] | 6-7/8" x 5-1/8" x 3-5/8", including connectors (H x W x D) 175 x 130 x 92 mm | Weight | 4 lbs.
