1794-ID21794-ID21794-ID2开关量：开关量只有两种状态，0、1，包括开入量和开出量，反映的是状态。数字量：数字量由多个开关量组成。如三个开关量可以组成表示八个状态的数字量。模拟量：模拟量是连续的量，数字量是不连续的。反映的是电量测量数值（如电流、电压）。1、开关量：为通断信号，无源信号，电阻测试法为电阻0或无穷大；也可以是有源信号，***叫法是阶跃信号，就是0或1，可以理解成脉冲量版主说的好，多个开关量可以组成数字量2、数字量：有0和1组成的信号类型，通常是经过编码后的有规律的信号。和模拟量的关系是量化后的模拟量。3、模拟量：连续的电压，电流等信号量，模拟信号是幅度随时间连续变化的信号，其经过抽样和量化后就是数字量。4、脉冲量：在瞬间电压或电流由某一值跃变到另一值的信号量。在量化后，其连续规律的变化就是数字量，如果其由0变成某一固定值并保持不变，其就是开关量备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————SpirentDLS400ADSLWirelineSimulatorDLS400HNDLS400C***ultronicsSpirentADSLSimulatorSpirentDLSTestworksXPSWirelessSimulatorXPS/26-M24Spirent/C***ultronics/DLSTestworksDLS400DLS400SpirentDLS400XDSLWirelineSimulatorDL4-400IA2SpirentDLS400ADSLWirelineSimulatorSpirentCommunicati***DLS400HEOperatignManualSPIRENTDLS400xDLSWIRELINESIMULATORSPIRENTDLS400ADSLWIRELINESIMULATORSpirentDLS5A02NTTNCSNetworkClockSupplySpirentC***ultronicsDLS400ADSLSPIRENTDLS5104JapaneseImpairmentGeneratorSpirentDLS5A02NTTNCSNetworkClockSupplySpirentVDSLProductionDLS6500TesterSPIRENTDLS5104JapaneseImpairmentGeneratorSpirentDLS-400SWirelineSimulatorSpirentDLS-6400VDSLProductionTesterSPIRENTDLS5204xDSL4-OutputCustomNoiseGeneratorSpirentDLS5104JapaneseImpairmentGeneratorModuleSpirentDLS400DL4-400ExDSLWirelineSimulator400ESpirentDLS3200HomePNATestLoopSimulatorDLS/SpirentDLS400ADLSWirelineSimulatorModuleSpirentDLS-5103ImpairmentGenADSLSHDSLHDSLHDSL2SPIRENTDLS5103ImpairmentGeneratorSPIRENTC***ULTRONICSDLS200HISDNWIRELINESIMULATORSPIRENTDLS5104JapaneseImpairmentGeneratorSpirentDLS400DL4400IA2xDSLWirelineSimulatorSPIRENTC***ULTRONICSDLS200HEV6WIRELINESIMULATORSPIRENTDLS-5103IMPAIRMENTGENERATORADSLHDSLISDNSPIRENTDLS6200TESTWORKSMPSDSLWIRELINESIMULATORSPIRENTDLS-400SV11ADSLWIRELINESIMULATORDLS400SpirentDLS400DL4-400J3ADSLWirelineSimulator400J3SpirentDLS400DL4-400J2ADSLWirelineSimulator400J2SPIRENTC***ULTRONICSDLS400E2MBITWIRELINESIMULATORSPIRENTC***ULTRONICSDLS400SADSLWIRELINESIMULATORSpirentDLS-5402DualOutputDifferential&CommonMode30xSpirentDLS6100JWireLineSimulator(DLS-6100J-R)SpirentDLS6100JWireLineSimulatorSpirentDLS-5A02NTTNCS1312NetworkClockSupplySPIRENTDLS5104JapaneseImpairmentGenerator(DLS-5​10)SPIRENTDLS5104JapaneseImpairmentGeneratorSpirentDLS6200MultilineProductionSimulatorSpirentDLS6500VDSLProductionTester(DLS-6526-24)SpirentDLS-5404DualADSL2++NoiseInjectionUnitSPIRENTDLS5403DVDSLNoiseInjectorJapan(DLS-5403D)SPIRENTDLS5200VDSLCUSTOMxDSLNoiseImpairmentGeneSPIRENTDLS5200VDSLCUSTOMxDSLNoiseImpairmentGen.SPIRENTDLS5104JapaneseImpairmentGeneratorSpirentDLS6100XPSWirelineSimulatorupto23,500ftinSpirentDLS90-24WirelineSimulatorSpirentDLS90-26WirelineSimulatorSpirentDLS5402DualOutputDifferential&CommonModeSpirentDLS-5A02NTTNCS1084NetworkClockSupplySpirentDLS5104JapaneseImpairmentGeneratorModule)
