about minimum system requirements, recommended system, and supported application
development environments (ADEs), refer to the readme, which is installed or available at
ni.com/manuals.
Unpacking the Kit
Notice To prevent electrostatic discharge (ESD) 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 computer chassis.
2. Remove the device from the package and inspect the device for loose components or any
other sign of damage.
Notice Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.
Preparing the Environment
Ensure that the environment you are using the PXIe-5841 in meets the following
specifications.

Choosing and Installing the Software
Software Options
NI provides three software options for programming the PXIe-5841—RFmx, NI-RFSA and
NI-RFSG instrument driver software.
Table 1. PXIe-5841 Software Options
Software
Option
Description Use Case
RFmx Provides a single-handle instrument
driver with built-in measurements.
You can use instrument driver
FPGA extensions to customize the
device FPGA using precompiled
bitfiles.
Use RFmx SpecAn to perform spectral
measurements.
Use RFmx Demod to perform
modulation quality measurements, such
as EVM.
Use RFmx personalities to perform
physical layer analysis on supported
communications and connectivity
signals.
NI-RFSA and
NI-RFSG
instrument
driver
The NI-RFSA and NI-RFSG APIs
each provide a fixed API for
interacting with your hardware.
NI-RFSA and NI-RFSG provide
standard IVI-based functionality
needed for most vector signal
analyzer and vector signal
generator applications.
You can use NI-RFSA and
NI-RFSG instrument driver FPGA
extensions to customize the device
FPGA using precompiled bitfiles.
Use NI-RFSA to create custom
measurements or applications that
require I/Q data.
Use NI-RFSG to generate continuous
wave (CW) or modulated waveforms.
Use NI-RFSA and NI-RFSG with the
NI Modulation Toolkit to develop
software-defined radio transmitters and
receivers.
Use NI-RFSG with the NI Modulation
Toolkit to create and generate
modulated signals to test receivers.
Related Information
Refer to the RFmx SpecAn Help, the NI-RFmx Demod Help, the NI RF Vector Signal Analyzers
Help, or the NI RF Signal Generators Help for more information about using the NI-RFmx,
NI-RFSA, and NI-RFSG instrument driver FPGA extensions.
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™.
PXIe-5841 Getting Started Guide | © National Instruments | 5
2. Install the driver software using NI Package Manager or by inserting your driver software
media into your computer.
If you do not already have NI Package Manager installed, visit ni.com/r/NIPMDownload
to download NI Package Manager. Refer to the NI Package Manager Manual for more
information about installing, removing, and upgrading NI software using NI Package
Manager.
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 PXIe-5841
Notice To prevent damage to the PXIe-5841 caused by ESD or contamination,
handle the module using the edges or the metal bracket.
You must install the software before installing the hardware.
Before you install the hardware, refer to the guidelines in the Maintain Forced-Air Cooling
Note to Users included with the module to ensure that the device can cool itself effectively.
This document is also available at ni.com/manuals.
The PXIe-5841 is a two-slot module with two backplane connectors. The module must be
installed into two adjacent chassis slots.
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.
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. If the chassis has a slot cooling capacity of 38 W, set the fan speed to HIGH.
Note Inadequate air circulation could cause the temperature inside the chassis
to rise above the optimal operating temperature for the device, potentially
causing thermal shutdown, shorter lifespans, or improper performance.
5. Position the chassis so that inlet and outlet vents are not obstructed.
6. Remove the black plastic covers from all the captive screws on the module front panel.
7. Identify two adjacent PXI Express-compatible slots in the chassis. The following figure
shows the symbols that indicate the slot types.

The PXIe-5841 can be placed in PXI Express peripheral slots, PXI Express Hybrid
peripheral slots, or PXI Express system timing slots.
8. Touch any metal part of the chassis to discharge static electricity.
9. Ensure that the ejector handle is in the unlatched (downward) position.
10. Hold the module by the edges and slide it into the empty compatible slots. Ensure the
base engages with the guides in the chassis.

11. Latch the module in place by pulling up on the ejector handle.
12. Secure the module 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.

13. Use slot blockers and cover all empty slots with filler panels to maximize cooling air
flow.
Note Proper airflow is critical to device operation.
14. Power on the chassis.
Direct Connections to the PXIe-5841
The PXIe-5841 is a precision RF instrument that is sensitive to ESD and transients. Ensure
you take the following precautions when making direct connections to the PXIe-5841 to avoid
damaging the device.
Notice Apply external signals only while the PXIe-5841 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
PXIe-5841 RF IN connector.
• If you are using nonisolated devices, such as a nonisolated 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
PXIe-5841 RF IN connector, ensure that the device cannot generate signal transients
greater than the RF and DC specifications of the PXIe-5841 RF IN connector.
