BIRD4410A Wattmeter, Multipower +/-5% Accuracy, Bird Electronics

Wattmeter, Multipower +/-5% Accuracy, MFR: Bird Electronics


4410A  Wattmeter, Multipower +/-5% Accuracy, MFR: Bird Electronics

4410A, Multipower Wattmeter with 9V Alkaline Battery -  ±5% Reading Accuracy
The wattmeter has 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 standard 9V alkaline 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 4410A
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
Accuracy ±5% of reading for any reading above 20% of the Power Range selected for FM or CW signals without AM. This accuracy is maintained for a full 37 dB dynamic range with each 4410 Element (except No. 4410-1 200 kHz-535 kHz which is accurate to ±10% of reading, and 4410-15 1.0-1.8 GHz and 4410-16 1.8-2.3 GHz which are accurate to ±8% of reading.)
Usuable Over Range To 120% of nominal full scale
Protection (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
Connectors QC Type (Female N normally supplied)
