4412A, Multipower Wattmeter with Rechargeable Battery - ±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
| Item No | 4412A |
| Item Name | Multipower Wattmeter |
| 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 | with N Connectors 1.25 max. to 2300 MHz |
