NI-RFSA along with the Nl Modulation Toolkit to analyze modulated signals to test receivers.Use the NI-RFSA SFP to interactively acquire data.Installing the SoftwareYou must be an Administrator to install Nl software on your computer.1.Install an ADE,such as LabVIEW or LabWindows/CVI.2.Download the driver software installer Package Manager downloads with the driver software to handle the installation.Refer to the Nl Package Manager Manual for more information about installing,removing,and upgrading Nl software using Nl Package Manager.3.Follow the instructions in the installation prompts.Note Windows users may see access and security messages during installation.Accept the prompts to complete the installation.4.When the installer completes,select Restart in the dialog box that prompts you to restart,shut down,or restart later.Installing the PXIe-5668Notice To prevent damage to the PXIe-5668 caused by ESD or contamination,handle the module using the edges or the metal bracket.8 PXIe-5668 Getting Started步 NoteYou must install NI-RFSA before installing the hardware.Before you install the hardware,refer to the guidelines in the Maintain Forced-Air Cooling Note to Users included with the module to ensure that the device can cool itself effectively.To use the included cables,you must install the PXIe-5624 IF digitizer immediately to the left of the PXIe-5606 RF downconverter module,and you must install the PXIe-5653 LO source module immediately to the right of the PXIe-5606 RF downconverter module.1.Ensure the AC power source is connected to the chassis before installing the module.The AC power cord grounds the chassis and protects it from electrical damage while you install the module.2.Power off the chassis.3.Inspect the slot pins on the chassis backplane for any bends or damage prior to installation.Do not install a module if the backplane is damaged.4.Remove the black plastic covers from all the captive screws on the module front panel.5.Identify a supported slot in the chassis.The following figure shows the symbols that indicate the slot types.Figure 2.Chassis Compatibility Symbols1.PXI Express System Controller Slot2.PXI Peripheral Slot3.PXI Express Hybrid Peripheral Slot4.PXI Express System Timing Slot5.PXI Express Peripheral Slot National InstrumentsPXIe-5668 Getting StartedPXIe-5668 modules can be placed in PXI Express peripheral slots,PXI Express hybrid peripheral slots,or PXI Express system timing slots.6.Touch any metal part of the chassis to discharge static electricity.7.Ensure that the ejector handle is in the downward(unlatched)position.8.Place the module edges into the module guides at the top and bottom of the chassis.Slide the module into the slot until it is fully inserted.Figure 1.Module Installation1.Chassis2.Hardware Module3.Ejector Handle in Downward(Unlatched)Position9.Latch the module in place by pulling up on the ejector handle.10.Secure the module front panel to the chassis using the front-panel mounting screws./Note Tightening the top and bottom mounting screws increases mechanical stability and also electrically connects the front panel to the chassis,which can improve the signal quality and electromagnetic performance.11.Cover all empty slots using either filler panels(standard or EMC)or slot blockers with filler panels,depending on your application.10 PXIe-5668 Getting StartedNote For more information about installing slot blockers and filler panels,go to on the chassis.Related tasks:Installing the SoftwareInterconnecting the PXIe-5668 ModulesComplete the following steps to interconnect the PXIe-5668 front panel connectors,as shown in the following figure.Notice The signal pins of this products input/output ports can be damaged if subjected to ESD.To prevent damage,remove power from the product before connecting cables and employ industry-standard ESD prevention measures during installation,maintenance,and operation.National InstrumentsPXIe-5668

cable center pins are correctly aligned and connected.The cable connectors should tighten without much torque or effort.Note If the SMA cable does not exactly align with the SMA connector,bend the cable slightly by hand to align the cable and the connector.The amount of bending should be minimal.The cables can be damaged by excessive bending.6.Carefully complete tightening all SMA connectors to 1 N-m using an appropriate torque wrench(not included)or torque screwdriver and SMA driver bit.Tighten only until the wrench clicks.A Caution Incorrect torque at SMA connections can damage device connectors,degrade signal fidelity and phase locked loop performance,or cause insertion loss.Use an appropriate torque wrench ortorque screwdriver and SMA driver bit to ensure all SMA connections are properly torqued.SMA connectors for connections to external equipment may require torque different from 1 N m,dependingon the connector type,material,and manufacturer.7.Power on your PXI Express chassis and controller system.If you are using a MXI device and a remote controller,ensure that the chassis is powered on prior to triggering the remote controller.Using the controller system before the chassis is powered on may cause installed devices to not appear in MAX.8.Verify that the ACCESS LED is on for all three modules.Related concepts:TroubleshootingRelated information:National InstrumentsPXIe-5668 Getting Started Refer to the Nl RFVector Signal Analyzers Help for information about how to make connections using an external dock,or how to connect multiple Nl 5668R modules.Direct Connections to the PXIe-5606The PXIe-5606 is a precision RF instrument that is sensitive to ESD and transients.Ensure you are making proper direct connections to the PXIe-5606 to avoid damaging the device.Notice Apply external signals only while the PXIe-5606 is powered on.Applying external signals while the device is powered off may cause damage.Ensure you are properly grounded when manipulating cables or antennas connected to the PXIe-5606RF IN connector.If you are using noninsulated devices,such as an RF antenna,ensure the devices are maintained in a static-free environment.If you are using an active device,such as a preamplifier or switch routed to the PXIe-5606RF IN connector,ensure that the device cannot generate signal transients greater than the RF and DC specifications of the PXIe-5606RF IN connector.PXIe-5606 RF Downconverter ModuleThe PXIe-5606 RF downconverter module front panel contains eight connecto
