4410A Multi-Power Portable Wattmeter, reading accuracy ±5%
Complete with 3-30 MHz 1KW slug and carrying case
USED, BUT NEVER SATO
Multiple power ranges selectable by front panel switch
•Accurate CW and FM power measurements with temperature compensation from 200 kHz to 2.3 GHz and 2 mW to 10 kW (depending on element)
•Uses special wide-spectrum 4410 series elements (elements sold separately). •Wide-spectrum accuracy over a 37 dB dynamic range.
•Quick Change (QC) connectors to minimize the need for adapters during critical measurements.
•Elements are not included, sold separately.
The Model 4410A uses the basic principles and appearance of the Model 43, but transforms it into a high-precision, high-dynamic range instrument. The linear range meter with mirrored scale 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 position depends on the position of the range selector 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 circuit operates on a standard 9V alkaline battery.
Product specifications:
- Accuracy: ±5% of reading for any reading above 20% of selected power range for FM or CW signals with no AM. This accuracy is maintained for a full 37 dB dynamic range with each 4410 element (except #4410-1 200 kHz-535 kHz which has an accuracy of ±10% of reading, and 4410-15 1.0-1.8 GHz and 4410-16 1.8-2.3 GHz which have an accuracy of ±8% of reading).
- Ambient Temperature Range: 4410-1 to -8 and -10 to -16 elements are temperature compensated for nominal accuracy from 0° to 50° C (32° to 122° F) and 4410-20 to -27 from 20° C to 30° C (68° to 86° F)
- Connector: QC type (normally supplied with N female connector)
- Finish: Gray powder coat
- Frequency Range: 200 kHz to 2.3 GHz CW or FM (elements sold separately)
- Insertion VSWR: with N connectors 1.25 max. at 2300 MHz
- Nominal Dimensions: 6 7/8" H x 5 1/8" W x 3 5/8" D, (175 mm x 130 mm x 92 mm)
- Overload Protection: up to 120% of nominal full scale (e.g. 12 W, 120 W, 1200 W or 12,000 W).
- No damage or degradation to the unit will occur, regardless of range switch position.
- Power Range: 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 kW or 2 W to 10 kW full scale in a single plug-in element.
- Any Bird Series 4410 element can be used.
- Weight: 3 lbs (1.4 kg)
