32-bit數(shù)字處理技術(shù)! Icom已經(jīng)把數(shù)字處理技術(shù)應(yīng)用在了IC-756PROII，開創(chuàng)了無線通訊領(lǐng)域的心范疇。IC-746PRO融合了32-bit數(shù)字處理技術(shù)能夠更加靈活的增強(qiáng)信號，同時(shí)降低干擾，提供了更高的信噪比。DigitalTwinPBT手動階式濾波器數(shù)字降噪AGC循環(huán)管理麥克風(fēng)均衡器數(shù)字RF語音壓縮.HF+50MHz+144MHz全波段覆蓋持續(xù)的100W功率輸出全模式數(shù)字調(diào)制解調(diào)IF濾波器多功能大屏幕LCD.可顯示如下：頻道名字功能鍵波段RTTY解碼屏幕記憶調(diào)制器內(nèi)容圖形SWRRTTY解調(diào)器編碼器大量的CW功能記憶調(diào)制器內(nèi)建天線調(diào)諧器SSB/CW同步調(diào)諧音頻抑制控制(VSC) 附加特性 三倍波段堆棧寄存器2種前置放大器20dBRF天線可調(diào)噪音抑制(101級)500Hz以下SSB模式的BPF功能1/4速度撥號功能(SSB-data,CW和RTTY模式)108個(gè)可選的DTCS和50個(gè)可選的CTCSS編碼/解碼器1750Hz音頻編碼選配高穩(wěn)定性晶體單元,CR-33810個(gè)備忘錄快速分裂功能 9.99kHzRIT和ITX計(jì)算機(jī)控制CI-VVOX可編程,記憶,選擇記憶和IF掃描IF發(fā)射音頻監(jiān)視102個(gè)記憶頻道9600bps數(shù)據(jù)終端AH-4控制電路自動TS功能選配聲音合成單元1Hz調(diào)諧和指示 技術(shù)指標(biāo) 一般指標(biāo)頻率范圍:Rx 0.030-60.000MHz* 108.000-174.000MHz* Tx 1.800- 1.999MHz* 3.500- 3.999MHz* 7.000- 7.300MHz* 10.100-10.150MHz* 14.000-14.350MHz* 18.068-18.168MHz* 21.000-21.450MHz* 24.890-24.990MHz* 28.000-29.700MHz* 50.000-54.000MHz*144.000-148.000MHz**Somefreq.bandsarenotguaranteed.模式:USB,LSB,CW,RTTY,AM,FM頻道數(shù)目:102(99regular,2scanedgesand1call)天線:SO-239 3(2forHF/50MHzand1for144MHzbands;50?)工作溫度:-10℃to+60℃頻率穩(wěn)定性:Lessthan?ppmfrom1min.to60min.afterpowerON.Afterthat,rateofstabilitychangeislessthan 1ppmat25℃.Temperaturefluctuations(0℃to+50℃)lessthan1ppm.Frequencyresolution:1Hz電源:13.8VDC 15%(negativeground)電流消耗:Tx Rx Max.power Standby Max.audio 23A 2.2A 3.0A 尺寸 (不含天線):287(W) 120(H) 316.5(D)mm; 重量(大約):9.0kg;ACC1接口:8-pinDINconnectorACC2接口:7-pinDINconnectorCI-V接口:2-conductor3.5(d)mm(1/8 )數(shù)據(jù)接口:MiniDIN6-pin 發(fā)射指標(biāo)輸出功率 (continuouslyadjustable):SSB,CW,RTTY, AM FM5-100W 5-40W調(diào)制系統(tǒng):SSB PSNmodulation AM Lowpowermodulation FM Phasemodulation亂真發(fā)射:50dB(HFbands) 60dB(50/144MHzbands)載波抑制:Morethan40dB無用邊帶抑制:Morethan55dBITXvariablerange: 9.999kHz麥克風(fēng):8-pinconnector(600?)ELE-KEY接口:3-conductor6.35(d)mm(1/4 )KEY接口:3-conductor6.35(d)mm(1/4 )SEND接口:Phono(RCA)ALC接口:Phono(RCA) 接收指標(biāo)接收系統(tǒng):3次轉(zhuǎn)換超外差中頻:1st64.455MHz(forallmodes) 2nd455kHz(forallmodes) 3rd36kHz(forallmodes)靈敏度(typical): FrequencyRange(MHz)SSB,CW,RTTY(at2.4kHzBW)AM(at6kHzBW)FM(at15kHzBW)0.50-1.799__13uV__1.80-27.990.16uV*12uV*1__28.0-29.990.16uV*12uV*10.5uV*150.0-54.00.13uV*21uV0.25uV*2144.0-148.00.1uV*31uV*30.1uV*310dBS/NforSSB,CW,RTTYandAM,12dBSINADforFM*1Pre-amp1isON, *2Pre-amp2isON, *3Pre-ampisON靜噪靈敏度 (Pre-amp:OFF):SSB,CW,RTTY FM Lessthan5.6uV Lessthan1uV選擇度 (representativevalue):SSB(BW:2.4kHz) CW(BW:500Hz) RTTY(BW:350Hz) AM(BW:6kHz) FM(BW:15kHz) Morethan2.4kHz/-6dB Lessthan3.2kHz/-40dB Lessthan3.6kHz/-60dB Lessthan4.3kHz/-80dB Morethan500Hz/-6dB Lessthan700Hz/-60dB Morethan360Hz/-6dB Lessthan650Hz/-60dB Morethan6.0kHz/-6dB Lessthan15.0kHz/-60dB Morethan12.0kHz/-6dB Lessthan20.0kHz/-60dB偽波和景象抑制比:Morethan70dB (HF,50MHzbands) Morethan60dB(144MHz) (exceptIFthroughon50MHzband)音量輸出功率 (at13.8VDC):Morethan2.0Wat10%distortionwithan8?loadRITvariablerange:?.999kHzPHONE接口:3-pinconnector6.35(d)mm(1/4 )外接揚(yáng)聲器:2-pinconnector3.5(d)mm(1/4 )/8? 天線調(diào)諧器阻抗范圍:16.7-150?unbalanced*1(HFbands) 20-125?unbalanced*2(50MHzband) *1LessthanVSWR3:1; *2LessthanVSWR2.5:1最小輸入功率:8W(HFbands),15W(50MHzband)調(diào)諧準(zhǔn)確性:VSWR1.5:1orless插入損失:Lessthan1.0dB(aftertuning) 附件:麥克風(fēng)直流電源線備用保險(xiǎn)絲CWkeyplug
