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.

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.
