Bird 4410 THRULINE Multipower Directional Wattmeter, 2 Slug Element (as shown in photo) NOTE:The following information on this item was pulled from the internet and should be verified by the manufacter. Bird 4410 Multipower Wattmeter BIRD 4410A Multipower Meter The 4410A high-sensitivity wattmeter is a solid choice for field-service applications where the greater dynamic range of the plug-in elements substantially reduce the number of elements needed to cover multiple power and frequency ranges. It is also well-suited to laboratory work where power levels as low as 2 milliwatts must be measured with high accuracy. Each 4410A wattmeter plug-in element is capable of reading seven different power ranges cover 0.002 to 10,000 watts. The power ranges of the different elements overlap and include: 0.002–10 W, 0.02–100 W, 0.2–1000 W and 2–10,000 W. All ranges are in frequency bands from 200 KHz to 2300 MHz. Any one of the seven power ranges is selected by a rotary switch located on the front of the wattmeter. Forward and reflected power measurements are accomplished by rotating the element. Exceptional ±5% of reading accuracy is achieved via a built-in temperature compensation circuit. This stated accuracy applies from 100% of full scale down to 20% of full scale across all seven ranges. 2mW to 10 W, 20mW to 100 W, 200 mW to 1 kW or 2 W to 10 kW full scale in one single Plug-in Element. Any Bird series 4410 Element may be used. with N connectors 1.25 max to 2300 MHz ±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 # 4410-1 200 KHz–535 kHz which is accurage 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). Elements 4410-1 through -8, and -10 through -16 are temperature compensated for rated accuracy from 0°C to 50°C (32° to 122°F), and 4410-20 through 27 from 20°C to 30°C (68° to 86°F). To 120% of nominal full scale (i.e. 12 W, 120 W, 1,000 W, or 12,000 W). No damage or degradation to the unit will result, regardless of the Range Selector Switch position. 24 hours min. with standard 9V Alkaline “transistor†battery (NEDA No. 1604A supplied) QC Type (Female N normally supplied) (includes only pictured connectors) 6 7/8†H x 5 1/8†W x 3 5/8†D Part Number: 4410A • Suggested Retail $730.00 ea.

This attenuated signal is NOT rectified (as in the standard measuring elements), but is brought out through a female BNC connector on top of the element. Coupler elements fit the standard sockets, but there are no dc output tabs on the element body since no dc is produced. An added convenience is rotating the element between 0¡ and 180¡ varies the amount of coupling like a variable attenuator. Minimum attenuation of the main line signal is the nominal coupling ± 1 dB shown for each unit within the stated frequency band. Select from table below. *The power rating of the directional couplers cannot exceed the peak and average power ratings of the transmission line. Item is in good physical condition with a few minor scratches. WE DID TURN KNOB TO BATTERY AND NOTICED THE NEEDLE MOVE, INDICATING A SOURCE OF POWER, otherwise unable to test. Comes as pictured only.
