Caution Clean the hardware with a soft, nonmetallic brush. Make sure that the

hardware is completely dry and free from contaminants before returning it to

service.

Note Refer to the NI PXIe-5698 Specifications at ni.com/manuals for complete

specifications.

Installing the Software

You must be an Administrator to install NI software on your computer.

1. Install an ADE, such as LabVIEW or LabWindows™/CVI™.

2. Insert the driver software media into your computer. The installer should open

automatically.

If the installation window does not appear, navigate to the drive, double-click it, and

double-click autorun.exe.

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 NI 5698

Caution To prevent damage to the device caused by ESD or contamination, handle

the device using the edges or the metal bracket.

1. Ensure the AC power source is connected to the chassis before installing the modules.

The AC power cord grounds the chassis and protects it from electrical damage while you

install the modules.

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.

10. Secure the device 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 with filler panels or use slot blockers to maximize cooling air flow.

Direct Connections to the NI 5698

The NI 5698 is a precision RF instrument that is sensitive to ESD and transients. Ensure you

take the following precautions when making direct connections to the NI 5698 to avoid

damaging the device.

Caution Apply external signals only while the NI 5698 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

NI 5698 RF IN connector.

• If you are using noninsulated devices, such as a noninsulated 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 NI 5698

RF IN connector, ensure that the device cannot generate signal transients greater than the

RF and DC specifications of the NI 5698 RF IN connector.

1. Use the 2.92 mm-to-2.92 mm cable to connect the RF OUT connector on the NI 5698

front panel to the RF IN connector on the NI 5606 front panel.

2. Hand-tighten all 2.92 mm cable ends on the 2.92 mm cable connectors. The cable

connectors should tighten without much torque or effort.

3. Carefully complete tightening all 2.92 mm connectors to 1 N · m using an appropriate

torque wrench or torque screwdriver and driver bit.

Caution Incorrect torque at 2.92 mm connections can degrade signal fidelity

and phase-locked loop (PLL) performance and may cause insertion loss. Use an

appropriate torque wrench or torque screwdriver and 2.92 mm driver bit to

ensure all 2.92 mm connections are properly torqued. 2.92 mm connectors for

connections to external equipment may require torque different from 1 N · m,

depending on the connector type, material, and manufacturer.

4. Power on your PXI Express chassis and controller system.

5. Verify that the ACCESS LED is illuminated on all modules.

LED Indications

ACCESS Indicates the basic hardware status of the module.

OFF—The module is not yet functional, or the module has detected a problem

with a PXI Express power supply rail.

AMBER—The module is being accessed. Accessed means that the device setup

registers are being written to in order to control the device.

GREEN—The module is ready to be programmed by NI-RFSA.

ACTIVE Indicates the module state.

OFF— The module is in a quiescent state.

AMBER—The module is waiting for a Reconfiguration Trigger from the

configuration list.

GREEN—The module is triggered and is running a step from the configuration

list.

RED—The module has detected an error state. An error state may indicate the

module has exceeded approved operating temperature and thermal shutdown has

occurred or that the module has detected a power supply failure. If the power

supply fails, contact NI technical support.

Configuring the NI 5698 in MAX

Use Measurement & Automation Explorer (MAX) to configure your NI hardware. MAX

informs other programs about which devices reside in the system and how they are configured.

MAX is automatically installed with NI-RFSA.

NI PXIe-5698 Getting Started Guide | © National Instruments | 9

1. Launch MAX.

2. In the configuration tree, expand Devices and Interfaces to see the list of installed

devices.

Installed devices appear under the name of their associated chassis.

3. Expand your Chassis tree item.

MAX lists all devices installed in the chassis. Your default device names may vary.

Note If you do not see your device listed, press <F5> to refresh the list of

installed devices. If the device is still not listed, power off the system, ensure

the device is correctly installed, and restart.

4. Record the device identifier MAX assigns to the hardware. Use this identifier when

programming the NI 5698.

5. To use the NI 5698 with the NI 5668R vector signal analyzer, you must associate the

NI 5698 with the NI 5606 RF downconverter in MAX.

Note This step is not required if you are using the NI 5698 as a stand-alone

device.

a) Select the system device with the appropriate downconverter in the configuration

tree.

b) In the Associated Devices section, use the RF Conditioning drop-down listbox to

select the NI 5698.

c) Click Save in the MAX toolbar.

Note Module associations may be lost when you move the modules to

different chassis slots.

6. Self-test the device by selecting the device in the configuration tree and clicking Self-Test

in the MAX toolbar.

The MAX self-test performs a basic verification of hardware resources.
