調(diào)頻調(diào)幅信號(hào)發(fā)生器Marconi 2022D

　　廠家：英國(guó)馬可尼

　　頻率范圍: 10 kHz to 1 GHz(7位液晶顯示精度10 Hz up to 100 MHz, 100 Hz above 100 MHz) 輸出幅度: -127 dBm to +13 dBm 調(diào)制：調(diào)頻、調(diào)幅、調(diào)相;外接調(diào)制;三種內(nèi)部調(diào)制頻率Aux modulation input 體積小巧，方便攜帶152 x367 mm , 7.5 kg 100組記憶設(shè)定強(qiáng)大的第二功能鍵用于快速故障定位和校準(zhǔn)Reverse power protection up to 50 W Choice of output cal. unitsOutput level can be offsetParameters can be incremented 輸出電平-127 to +13 dBm (0.2 uV to 2 V EMF). When AM is selected the max. output power reduces linearly with AM depth to +7 dBm at maximum AM depth.

　　單位單位可以是uV, mV, V EMF or PD; dB相當(dāng)于1uV, 1 mV EMF or PD; dBm.

　　顯示4位LCD 顯示精度0 .1 dB 輸出電平精度+1 dB(-10 dBm以上)+2 dB(-10 dBm以下)

　　輸出電平平坦度Better than +0.5 dB from 10 kHz to 1 GHz for output levels above -7 dBm.

　　輸出阻抗50歐N型頭VSWR is better than 1.5:1 for output levels below -7 dBm.

　　最大單邊帶噪聲-120 dBc/Hz Harmonics (noise) -35 dBc Non-harmonics (noise) -40 dBc 外接頻率參考10 MHz
