Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may
occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with radio
and television reception and prevent unacceptable performance degradation, install and use this
product in strict accordance with the instructions in the product documentation.
Furthermore, any modifications to the product not expressly approved by National Instruments
could void your authority to operate it under your local regulatory rules.

Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories.
Caution To ensure the specified EMC performance, the length of all I/O cables
must be no longer than 3 m (10 ft).
Caution BNC version only—Electromagnetic interference can adversely affect
the measurement accuracy of this product. The construction of a BNC coaxial cable
is inherently unbalanced in that the outer conductor (LO) is used as a shield for the
inner conductor (HI). However, for functional reasons, there is no input configuration
of the PXIe-4464 that directly connects the LO terminal to the chassis ground.
Without a direct connection to chassis ground, the outer conductor does not act as a
shield for unwanted noise and may act as an antenna for coupling noise into the
module inputs. For single-ended measurements, the noise immunity for the system
can be improved by directly connecting the outer conductor to the chassis or earth
ground at the load end of the cable. For differential measurements, where such a
connection is inherently not possible, the BNC cable can alternatively be wrapped in
a separate grounded shield. In addition, you might need to use snap-on ferrite beads
or other remedial measures to improve electromagnetic compatibility.
Unpacking the Kit
The PXIe-4464 module ships in an antistatic package to prevent electrostatic discharge from
damaging module components.
Caution To prevent electrostatic discharge from damaging the device, ground
yourself using a grounding strap or by holding a grounded object, such as your
computer chassis:
1. Touch the antistatic package to a metal part of the grounded object before removing the
module from package.
2. Remove the module from the package and inspect the module for loose components or any
other sign of damage.
Caution Never touch the exposed pins of connectors
3. Unpack any other items and documentation from the kit.
Notify NI if the module appears damaged in any way. Do not install a damaged module. Store
the module in the antistatic package when the device is not in use.

Preparing the Environment
Ensure that the environment you are using the PXIe-4464 in meets the following specifications.
Operating ambient temperature ........................ 0 °C to 55 °C
(IEC 60068-2-1, IEC 60068-2-2)
Operating relative humidity.............................. 10% to 90%, noncondensing
(IEC 60068-2-56)
Altitude ............................................................. 2,000 m (800 mbar)
(at 25 °C ambient temperature)
Pollution Degree ............................................... 2
Indoor use only.
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 PXIe-4464 Specifications at ni.com/manuals for complete
specifications.

The following additional items, not included in the module kit, are necessary to operate the
PXIe-4464:
• PXI Express chassis with
– controller, or
– MXI-Express (card or built-in)
• (optional) LabVIEW
Note For the list of LabVIEW versions supported by a specific version of
NI-DAQmx, refer to the NI-DAQmx Readme, available on the version-specific
download page at ni.com/downloads or on the installation media.

Install the Software
Software support for the PXIe-4464 is provided by NI-DAQmx. The DAQ Getting Started
Guide, which you can download at ni.com/manuals, offers step-by-step NI-DAQmx
instructions for installing software and hardware, configuring channels and tasks, and getting
started developing an application. For detailed NI software version support, refer to the
NI-DAQmx Readme.
You must install the software before using the hardware.
Note You must be an Adminstrator to install NI software on your computer.
1. Install an ADE, such as LabVIEW or LabWindows™/CVI™.
2. Install the latest service packs for your operating system.
3. 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.
4. 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.
5. When installation completes, select Restart in the dialog box that asks if you want to
restart, shut down, or restart later.
Install the Hardware
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling document.
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 module. The
AC power cord grounds the chassis and protects it from electrical damage while you install
the module.
2. Power off the chassis.
Caution To protect yourself, the chassis, and the PXIe-4464 from electrical
hazards, leave the chassis powered off until you finish installing the PXIe-4464
module.

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 PXIe-4464 module can be placed only in the
supported slot types identified in Table 1. Figure 1 shows the slot type symbols of the
various slot types. Refer to your chassis documentation for more details
Figure 1. PXI/PXIe Chassis Slot Type Symbol Location
6. Touch any metal part on the chassis to discharge any static electricity.
7. Ensure that the injector/ejector handle is in the unlatched (downward) position.
Caution When installing the module, make sure both edges are positioned inside
the guides and that the module components do not come into contact with adjacent
modules.

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 serves to electrically connect the front panel to the chassis, which
can improve the signal quality and electromagnetic performance.
11. Cover all empty slots using EMC filler panels or slot blockers to maximize cooling air flow,
depending on your application.
12. Power on the chassis.

Configuring the PXIe-4464 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-DAQmx.
1. Launch MAX.
2. In the Configuration pane, expand Devices and Interfaces to see a list of installed devices.
Installed devices appear under the name of their associated chassis.
Note If you are using the PXIe-4464 with the LabVIEW Real-Time Module,
expand Remote Systems. Find your target IP address or name, expand it, and then
expand Devices and Interfaces.
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 hardware 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 PXIe-4464.
