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 5694
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 connectors 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.

9. Latch the module in place by pulling up on the ejector handle.
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 using filler panels or slot blockers to maximize cooling air flow.
12. Power on the chassis.

Direct Connections to the NI 5694
The NI 5694 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 5694 to avoid
damaging the device.
NI PXIe-5694 Getting Started Guide | © National Instruments | 5
Caution Apply external signals only while the NI 5694 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 5694 IF 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 5694
IF IN connector, ensure that there are no signal transients greater than the RF and DC
specifications for the device that are being generated and sourced to the NI 5694 IF IN
connector.
NI 5694 Front Panel
The NI 5694 IF conditioning module front panel contains five connectors and two LEDs.

Table 1. Device Front Panel Icon Definitions
Refer to the user documentation for required maintenance measures to ensure user
safety and/or preserve the specified EMC performance.
The signal pins of this product's input/output ports can be damaged if subjected to
ESD. To prevent damage, turn off power to the product before connecting cables and
employ industry-standard ESD prevention measures during installation, maintenance,
and operation.
Table 2. NI 5694 IF Conditioning Module Front Panel Connectors
Connector Use
IF OUT Provides the conditioned intermediate frequency (IF) signal to the input
connector on a digitizer, for example, the IF IN connector on the
NI PXIe-5622.
IF IN Receives a signal from the IF OUT connector of an RF downconverter, for
example, the IF OUT connector of the NI PXIe-5603 or NI PXIe-5605.
REF/LO IN Connects to a 10 MHz clock signal or a 215 MHz LO signal.
If your application uses the NI 5694 in downconversion mode in a phase-
coherent system, connect the REF/LO IN connector on a slave NI 5694 to a
215 MHz LO signal.
REF OUT Output terminal for a 10 MHz signal received at the REF/LO IN connector.
LO OUT Output terminal for either a 215 MHz LO signal received at the REF/LO IN
connector or an internally generated 215 MHz LO signal.

Table 3. NI 5694 IF Conditioning Module Front Panel LEDs
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 power 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 5694 in MAX
Use Measurement & Automation Explorer (MAX) to configure your National Instruments
hardware. MAX informs other programs about which devices reside in the system and how
they are configured. MAX is automatically installed with NI-RFSA.
1. Launch MAX.
2. In the configuration tree, double-click Devices and Interfaces to see the list of installed
devices.
Note If you are using the NI 5694 with the LabVIEW Real-Time Module,
expand Remote Systems. Find your target IP address or name, expand it, and
then expand Devices and Interfaces.
Installed devices appear under the name of their associated chassis.
3. Expand your Chassis tree item.
8| ni.com | NI PXIe-5694 Getting Started Guide
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 5694.
5. To use the NI 5694 with the NI 5667 spectrum monitoring receiver, you must associate
the NI 5694 with the RF downconverter in MAX.
Note This step is not required if you are using the NI 5694 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 IF Conditioning drop-down listbox to
select the NI 5694.
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.

Troubleshooting
If an issue persists after you complete a troubleshooting procedure, contact NI technical
support or visit ni.com/support.
Why Is the ACCESS LED Off When the Chassis is
On?
The LEDs may not light until the device has been configured in MAX. Before proceeding,
verify that the NI 5694 appears in MAX.
If the ACCESS LED fails to light after you power on the chassis, a problem may exist with the
chassis power rails, a hardware module, or the LED.
NI PXIe-5694 Getting Started Guide | © National Instruments | 9
Caution Apply external signals only while the NI 5694 is powered on. Applying
external signals while the device is powered off may cause damage.
1. Disconnect any signals from the module front panels.
2. Power off the chassis.
3. Remove the module from the chassis and inspect it for damage. Do not reinstall a
damaged device.
4. Reinstall the module in a different chassis slot.
5. Power on the chassis.
6. Verify that the device appears in MAX.
7. Reset the device in MAX and perform a self-test.
What Should I Do if the NI 5694 Doesn't Appear in
MAX?
1. In the MAX configuration tree, click Devices and Interfaces.
2. Expand the Chassis tree to see the list of installed devices, and press <F5> to refresh the
list.
3. If the module is still not listed, power off the system, ensure that all hardware is correctly
installed, and restart the system.
4. Navigate to the Device Manager.
Operating System Description
Windows 8 Right-click the Start screen, and select All apps»Control Panel»
Hardware and Sound»Device Manager.
Windows 7 Select Start»Control Panel»Device Manager.

Manager.
5. If you are using a PXI controller, verify that a National Instruments entry appears in the
system device list. Reinstall NI-RFSA and the device if error conditions appear in the list.
If you are using an MXI controller, right-click PCI-to-PCI Bridge, and select Properties
from the shortcut menu to verify that the bridge is enabled.
What Should I Do if the Module Fails the Self-Test?
1. Restart the system.
2. Launch MAX, and perform the self-test again.
3. Power off the chassis.
