鳥牌Bird4412A型通過式功率計駐波表
多功率射頻功率計,讀取精度為5%
4412A型射頻功率表采用了43型的基本原理和"外觀和感覺",但將其轉(zhuǎn)換成一種高度精確的高動態(tài)范圍儀器。 該儀表有兩個刻度尺,0-1刻度尺和0-3刻度尺.
電力被讀取為指針指示的值的倍數(shù),小數(shù)點位置取決于范圍開關(guān)位置和在插件元素上打印的因子。每個元件所覆蓋的功率范圍為300兆瓦至1千瓦和2瓦至10千瓦,全尺寸。對大多數(shù)元素來說,精度是+/-5%,在全尺度的20%以上。該電路使用可充電電池。

特點
Multipower, ±5% Reading Accuracy
The Model 4412A uses the basic principles and “l(fā)ook 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. (1.8 kg)
