PAGEPAGE169安捷倫函數(shù)信號發(fā)生器Agilent33120A的性能與使用說明安捷倫函數(shù)信號發(fā)生器33120A是數(shù)字式函數(shù)信號發(fā)生器。其內(nèi)部永久存儲著正弦波、方波、三角波、噪聲、鋸齒波、sin(x)/x、負鋸齒波、指數(shù)上升波、指數(shù)下降波、心電波，共10種函數(shù)信號。其中，正弦波、方波的頻率范圍為100μHz－15MHz，幅值范圍為100mVP-P－10VP-P。函數(shù)信號發(fā)生器有一個HP-IB（IEEE-488）接口和一個RS-232接口，計算機通過接口可遙控函數(shù)信號發(fā)生器，在計算機中使用HPBASIC語言程序或C語言程序，能產(chǎn)生12bit40Msa/s的任意波形，通過接口寫入函數(shù)信號發(fā)生器，函數(shù)信號發(fā)生器有四個可存儲16000點的任意波形存儲器。其具體的性能指標和基本操作方法見本節(jié)后摘錄自“Agilent33120AFunctionGeneratorUserGuide”的內(nèi)容。要知道詳細的內(nèi)容應閱讀該儀器的“用戶手冊”。⒈信號源顯示電壓與實際輸出電壓理想信號源的內(nèi)阻應為零。若實際信號源的內(nèi)阻為零，則信號源輸出端一旦短路或負載電阻過小，信號源就會因功率過載而損壞。實際信號源一般都在其輸出端串接一個電阻Rs，使信號源既使短路，在短時間內(nèi)也不會因功率過載而損壞，由此使信號源的保護電路有時間實現(xiàn)對信號源輸出電路進行保護，同時發(fā)出過載警告。圖1信號源輸出電壓示意圖稱信號源輸出端串接電阻Rs圖1信號源輸出電壓示意圖安捷倫33120A（以下簡稱為信號源）的內(nèi)阻為50Ω。由于有了信號源內(nèi)阻Rs，如圖1，信號源輸出端的電壓，即負載電阻RL上的電壓，是信號源的電源Es在信號源內(nèi)阻Rs和負載電阻RL上的分壓，即Vo≠Es。信號源內(nèi)設(shè)置了兩個負載電阻值，開機時默認為RLD=50Ω,通過操作可修改為RLD→∞。在信號源開機默認為RLD=50Ω時，信號源內(nèi)部的電壓源輸出的電壓為Es，信號源顯示屏上顯示的電壓是（1）若實際負載不是50Ω，那么負載上實際得到的電壓Vo為（2）即信號源顯示屏上顯示的電壓與負載上得到的實際電壓不一樣，Vo≠VDisplay。在實際使用時，當信號源的負載電阻，即電路的輸入電阻RL與50Ω可比時，信號源宜取RLD=50Ω狀態(tài)，這時Vo≠VDisplay，但是VDisplay比較接近Vo。信號源的負載電阻，即電路的輸入電阻RL>>50Ω時，信號源宜取RLD→∞狀態(tài)，這時Vo≠VDisplay，但是VDisplay比較接近Vo。Vo究竟為多少應使用電壓表具體測量。⒉關(guān)于本信號源的具體性能指標和基本操作使用方法以下關(guān)于本信號源的具體性能指標和基本操作使用方法摘自“Agilent33120AFunctionGeneratorUserGuide”。直接閱讀原版用戶手冊，比閱讀翻譯后的用戶手冊更有利于了解關(guān)于本信號源的具體性能指標和基本操作使用方法。在使用本信號源前，使用者必須閱讀以下的內(nèi)容。附錄Agilent33120AFunctionGeneratorUserGuideSpecificationsWAVEFORMSStandardWaveforms:Sine,Square,Triangle,Ramp,Noise,DCvolts,Sine(x)/x,NegativeRamp,ExponentialRise,ExponentialFall,CardiacArbitraryWaveforms:WaveformLength:8to16,000pointsAmplitudeResolution:12bits(includingsign)SampleRate:40MSa/secNon-VolatileMemory:Four16,000-pointwaveformsFREQUENCYCHARACTERISTICSSine:100μHz–15MHzSquare:100μHz–15MHzTriangle:100μHz–100kHzRamp:100μHz–100kHzNoise(Gaussian):10MHzbandwidthArbitraryWaveforms:8to8,192points:100μHz–5MHz8,193to12,287points:100μHz–2.5MHz12,288to16,000points:100μHz–200kHzResolution:10μHzor10digitsAccuracy:10ppmin90days,20ppmin1year,18℃–28℃TemperatureCoefficient:<2ppm/℃Aging:<10ppm/yrSINEWAVESPECTRALPURITY(into50?)HarmonicDistortionDCto20kHz:-70dBc20kHzto100kHz:-60dBc100kHzto1MHz:-45dBc1MHzto15MHz:-35dBcTotalHarmonicDistortionDCto20kHz:<0.04%Spurious(non-harmonic)Output(DCto1MHz):<-65dBcOutput(>1MHz):<-65dBc+6dB/octavePhaseNoise:<-55dBcina30kHzbandSIGNALCHARACTERISTICSSquarewaveRise/FallTime:<20nsOvershoot:<4%Asymmetry:1%+5nsDutyCycle:20%to80%(to5MHz)40%to60%(to15MHz)Triangle,Ramp,ArbRise/FallTime:40ns(typical)Linearity:<0.1%ofpeakoutputSettlingTime:<250nsto0.5%offinalvalueJitter:<25nsOUTPUTCHARACTERISTICS1Amplitude(into50?):250mVpp–10VppAccuracy(at1kHz):±1%ofspecifiedoutputFlatness(sinewaverelativeto1kHz)<100kHz:±1%(0.1dB)100kHzto1MHz:±1.5%(0.15dB)1MHzto15MHz:±2%(0.2dB)Ampl≥3Vrms1MHzto15MHz:±3.5%(0.3dB)Ampl<3VrmsOffset(into50?):3±5Vpkac+dcAccuracy4±2%ofsetting+2mVOutputImpedance:50?fixedResolution:3digits,AmplitudeandOffsetOutputUnits:Vpp,Vrms,dBmIsolation:42VpkmaximumtoearthProtection:Short-circuitprotected±15Vpkoverdrive<1minuteMODULATIONCHARACTERISTICSAMModulationCarrier-3dBFreq:10MHz(typical)Modulation:AnyinternalwaveformplusArbFrequency:10mHzto20kHz(±0.05%to2.5kHz,thendecreaseslinearlyto±0.4%atupperlimit)Depth:0%to120%Source:Internal/ExternalFMModulationModulation:AnyinternalwaveformplusArbFrequency:10mHzto10kHz(±0.05%to600Hz,thendecreaseslinearlyto±0.8%atupperlimit)PeakDeviation:10mHzto15MHzSource:InternalOnlyBurstModulationCarrierFrequency:5MHzmax.Count:1to50,000cycles,orInfiniteStartPhase:-360°to+360°InternalRate:10mHzto50kHz±1%GateSource:InternalorExternalGate5TriggerSource:Single,External,orInternalRateFSKModulationFrequencyRange:10mHzto15MHz(±0.05%to600Hz,thendecreaseslinearlyto±4%atupperlimit)InternalRate:10mHzto50kHzSource:Internal/External(1MHzmax.)FREQUENCYSWEEPType:LinearorLogarithmicDirection:UporDownStartF/StopF:10mHzto15MHzTime:1msto500sec±0.1%Source:Single,External,orInternalREAR-PANELINPUTSExternalAMModulation:±5Vpk=100%Modulation5k?InputResistanceExternalTrigger/FSKBurstGate:5TTL(lowtrue)Latency:1.3μsJitter:25nsSYSTEMCHARACTERISTICSConfigurationTimes6FunctionChange:780msFrequencyChange:730msAmplitudeChange:30msOffsetChange:10msSelectUserArb:100msModulationParameterChange:<350msArbDownloadTimesoverGPIB:ArbLengthBinaryASCIIIntegerASCIIReal816,000points8sec81sec100sec8,192points4sec42sec51sec4,096points2.5sec21sec26sec2,048points1.5sec11sec13secArbDownloadTimesoverRS-232at9600Baud:9ArbLengthBinaryASCIIIntegerASCIIReal1016,000points35sec101sec134sec8,192points18sec52sec69sec4,096points10sec27sec35sec2,048points6sec14sec18sec1
