厦门莫格电气自动化有限公司销售Honeywell霍尼韦尔620-0076您迈开询价的一小步，我还您成功的一大步。​620-0076620-0076620-0076按照设计的硬件结构连接好硬件，设置波形信息，基带信号为30Hz正弦波，调频副载波9960Hz，频偏480Hz，调制系数0.3。考虑机器性能及运行时间，VOR信号以1MHz为例。计算得出的波形存储到文件中，以便在波形产生程序里调用。在波形产生程序中，先对设备进行初始化和参数调整，设定板卡地址，功率为-10dBm，中心频率1MHz，模式为“ArbW***eform”。调用时候采用IQ调制，I路为调制信号，Q路为0。写入数据时选择与生成时相同的采样率，才能保证生成信号的频谱正确。信号产生模块持续运行，并调用数字化仪进行采集。同样需要设置虚拟通道，量程&plu***n;1V，信号类型“AIVoltage”，采样频率须满足乃奎斯特定理，此处选为8MHz，采样时钟设定为“ContinuousSamples”，持续时间1秒。采样后的数据可以实时在波形图表中显示，并通过“写入波形数据到文件.vi”存入文件，以便后续调用。为实现对信号的测量和验证，需要对采集的波形进行解调并还原出相应的信息。采集到的VOR空间合成信号经过相干解调后得到空间合成信号的外包络，包括30Hz的可变相位信号，和9960Hz的调频副载波。30Hz可变相位信号经过30Hz滤波器直接得到，前面板可见其时域、频域波形以及频率、相位和幅值等信息；9960Hz副载波经过滤波后鉴频，得到30Hz基准相位信号，前面板可见其相应参数。基准相位信号与可变相位信号的相位差可指示当前的方位信息，读书为VOR方位角。运行后的前面板如图5所示。程序运行时，其中的各个标签页可以轮流显示，按下右下方的“暂停”钮可以锁定当前标签页。图5综测仪前面板4、结论软件无线电技术目前、民用通信领域已经有广泛的应用。基于此技术的测试设备因为其开放性和灵活性，比传统设备有更加广阔的应用前景。而数字化仪正是实现模拟信号向数字信号过渡的关键。经验证，凌华科技PCI-9846高速数字化仪安装简便，操作界面人性化，可以在LabVIEW环境下方便地调用，胜任复杂模拟信号的准确采集和模数转换，并能存储成波形文件便于后续调用。限于技术水平和电脑性能，不能做更高频率的采样和信号处理实验，有待今后工作中继续研究改进FISHER546*NEWNOBOX*PHOENIXCONTACTFLKM-D50-SUB/S*USED*POWERONEPOWERSUPPLYMAP55-4002*NEW*PANALARM070-0106-3-01*NEWOUTOFBOX*PARTLOW104511516SENSORELEMENT*NEWINBOX*CORCOM5VR1F7202EMIFILTER120/250V*USED*CXM4/0600VCONNECTOR*USED*NO***ON274578A*NEWOUTOFABOX*NO***ON274179A*NEWINAFACTORYBAG*MAC6521B-311-PM-11?1DA*USED*WESTINGHOUSECONTROLRELAY120V***A*USED*HONEYWELL***37G1028GASPRESSURESWITCH*USED*ALLENBRADLEYINPUTMODULE1771-IBN*USED*LOTOF3ASCO238210-032-DVALVE*USED*VERSAVALVE,FOUR-WAYVSG-4322-XX-A12?0*NEWINBOX*TELEMECANIQUEXCS-PA593*USED*VIDEOJET378297-101*NEWINABOX*TEXASINSTRUMENTS30504BPROGRAMMABLECONTROLLER*USED...ALTECHCORPORATIONMA1.6UCIRCUITBREAKER*USED*TRERICED069110-30PSI*NEWINABOX*HEINEMANNAD2S-B3B2-L0-DN?-H-A-61*USED*YAMAHACORPORATIONG776420*NEWOUTOFBOX*STEP-UPSR-700-ADJDCPOWERSTEPUPREGULATOR*USED*CONTECDA12-4(PC)*NEWINBOX*AUTOMATIONDIRECTD2-230*NEWINABOX*CLARKRELIANCECORP.RELAYRECID-23R120VAC*USED*INDUSTRIALCONTROLEQUIPMENTMIO-EXP10BASE10-SLOTEX...ALLENBRADLEY154959REV.02REMOTEI/OINTERFACE*USED*LOTOF3HUMPHREY5-S-1AIRCYLINDER*USED*FISHER546*NEWNOBOX*PHOENIXCONTACTFLKM-D50-SUB/S*USED*POWERONEPOWERSUPPLYMAP55-4002*NEW*PANALARM070-0106-3-01*NEWOUTOFBOX*PARTLOW104511516SENSORELEMENT*NEWINBOX*CORCOM5VR1F7202EMIFILTER120/250V*USED*CXM4/0600VCONNECTOR*USED*NO***ON274578A*NEWOUTOFABOX*NO***ON274179A*NEWINAFACTORYBAG*LOTOF2LUMBERGAUTOMATION0976PMC101CONNECTOR*NEWO...STEP-UPSR-700-ADJDCPOWERSTEPUPREGULATOR*USED*CONTECDA12-4(PC)*NEWINBOX*AUTOMATIONDIRECTD2-230*NEWINABOX*GENUINEBINDICATORVRF2A0G1N*USED*CLARKRELIANCECORP.RELAYRECID-23R120VAC*USED*INDUSTRIALCONTROLEQUIPMENTMIO-EXP10BASE10-SLOTEX...ALLENBRADLEY154959REV.02REMOTEI/OINTERFACE*USED*LOTOF3HUMPHREY5-S-1AIRCYLINDER*USED*FISHER546*NEWNOBOX*PHOENIXCONTACTFLKM-D50-SUB/S*USED*POWERONEPOWERSUPPLYMAP55-4002*NEW*PANALARM070-0106-3-01*NEWOUTOFBOX*PARTLOW104511516SENSORELEMENT*NEWINBOX*CORCOM5VR1F7202EMIFILTER120/250V*USED*CXM4/0600VCONNECTOR*USED*NO***ON274578A*NEWOUTOFABOX*NO***ON274179A*NEWINAFACTORYBAG*LOTOF2LUMBERGAUTOMATION0976PMC101CONNECTOR*NEWO...NORGRENK71DA00KC0KL6*NEWNOBOX*MACVALVE45A-AA2-DACA-1C?A*NEW*GASTCORP.6AM-FRV-5AAIRMOTOR*USED*SYLVANIACIRCUITBREAKERSEH-3-C-40*NICE*LOTOF2IDECRR2P-U120VRELAY*USED*SPRECHER+SCHUHCS4-40ECONTROLRELAY120V*USED*LOTOF2WOODHEAD104000A01F120*USED*CONVERTEAMMVC3031-4003CONTROLLER*NEWINABOX*YAMADANDP-5FST*NEWINABOX*JOHNCRANETYPE9TQF51171316SS*NEWINABOX*NUMATICSVALVE12SAD4410A*NICE*GEPUSHBUTTONCR2940NP311C*USED*STI4193001*USED*MISUBISHIA1SHCPUCPUUNIT*USED*ACTAIREPNEUMATICPOSITIONER*USED*ROTACACTUATORLP-11-2V*USED*SEIMENS3VE1010-8J*USED*SEWEURODRIVEBG3,0*USED*SIEMENS7PU6040-7NE30*USED*ELECTROMAGNETICINDUSTRIESEAIAF*USED*EUCHNERGLBF-02-D16-502*USED*CTCPJ864LCABLEREDUCTIONBOX*USED*KYSOR7C9365*USED*GE55-501463G4460V*USED*CKDROAC200V/DC24V*USED*MICROSWITCHMHP-D31LPHOTOELECTRICSENSOR*USED*FISHER2F9644*USED*LOTOF3SPEEDAIRE1A429*USED*FOXBOROM40G*USED*EMERSON02-766375-00DCBUSSENSORBOARD*USED*BELIOT315-0621-0013MMBOARD*USED*BALANCETECHNOLOGY18860C*USED*8D15176REV.BBOARD*USED*DYNAMATIC15-461-3*USED*HYDRECLAIM61-HYBRAINBOARD*USED*MICROTRAK805-317-01CONTROLPANELSERIES9400*USED*KRAUS&NAIMERC11*USED*SENSORTRONICS60048-100*USED*35951BOARD*USED*)
