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.
Note If installing from the NI Device Drivers DVD, select Modular
Instruments»NI-SCOPE for installation.
4. When the installer completes, select Restart in the dialog box that prompts you to restart,
shut down, or restart later.
5. If you are using a system running the LabVIEW Real-Time Module, download
NI-SCOPE to the target using Measurement & Automation Explorer (MAX). For more
information, refer to the Max Remote Systems Help by selecting Help»Help Topics»
Remote Systems in MAX.
Installing the Spectral Measurements Toolkit
The Spectral Measurements Toolkit is packaged with the NI 5922 (32 MB/ch and 256 MB/ch
only). The Spectral Measurements Toolkit extends the capability of the NI 5922 to include
frequency- and modulation-domain measurements and analysis of analog-modulated IF
signals.
To use the full functionality of the NI 5922, you must install the toolkit, and it must be
installed after you install NI-SCOPE.
1. Insert the Spectral Measurements Toolkit DVD.
2. Install the Spectral Measurements Toolkit for the ADE you intend to use by following the
instructions in the installation window.
3. When the installation completes, remove the Spectral Measurements Toolkit DVD.
4. Restart your system.

Installing the Hardware
Installing the NI PXI-5922
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.

PXI modules can be placed in PXI peripheral slots or PXI Express Hybrid peripheral
slots. PXI Express 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 unlatched (downward) position.
8. Place the module edges into the module guides at the top and bottom of the chassis. Slide
the device into the slot until it is fully inserted.

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.
Caution It is important to completely screw the device into the slot, both for
mechanical stability and for creating a solid ground connection, which reduces
signal noise. Improperly secured devices may affect the accuracy of device
specifications.
11. Cover all empty slots using filler panels or slot blockers to maximize cooling air flow.
12. Power on the chassis.
Note For more information about maximizing cooling air flow, refer to the
Maintain Forced-Air Cooling Note to Users included in your kit.
Installing the NI PCI-5922
1. Power off and unplug the computer.
2. Access the computer system expansion slots. This step might require you to remove one
or more access panels on the computer case.
3. Locate a compatible slot and remove the corresponding slot cover on the computer back
panel. NI PCI-5922 modules can only be inserted into PCI slots.
Tip To maximize airflow and extend the life of the PCI device, leave any
adjacent PCI slots empty.
4. Touch any metal part of the computer to discharge any static electricity.
5. Insert the module into the slot you selected. Gently rock the module in to place without
forcing it.

6. Secure the module mounting bracket to the computer back panel rail.
Note Tightening the top mounting screw increases mechanical stability and
also electrically connects the front panel to the chassis, which can improve the
signal quality and electromagnetic performance.
7. Some computer manufacturers use a securing lever made of plastic to secure PCI devices;
such a lever is unacceptable and must be removed. Use the screw provided in the kit to
screw down the device. Otherwise, you must use a different computer chassis.
8. Replace any access panels on the computer case.
9. Plug in and power on your computer.
10. Verify that spread-spectrum clocking is enabled in the PC BIOS. For information about
how to verify this setting, refer to the PC user documentation
Note For SMC-based devices, spread-spectrum clocking varies the clock
signal to spread the timing clock signal over a small frequency range. Disabling
spread-spectrum clocking may affect the accuracy of device specifications.
Hardware Front Panel Connectors
Refer to the following figure and table for the NI 5922 front panels and signal connectors.
