Choosing and Installing the Software
Software Options
NI provides three software options for programming the PXIe-5840—NI-RFmx, NI-RFSA
and NI-RFSG instrument driver software.
Table 1. PXIe-5840 Software Options
Software
Option
Description Use Case
NI-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 NI-RFmx SpecAn to perform
spectral measurements.
Use NI-RFmx Demod to perform
modulation quality measurements, such
as EVM.
Use NI-RFmx personalities to perform
physical layer analysis on supported
cellular signals.
NI-RFSA and
NI-RFSG
instrument
driver
The NI-RFSA and NI-RFSG APIs
each provide a fixed API for
interacting with your PXIe-5840
device.
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 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 NI-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 NI LabVIEW.
PXIe-5840 Getting Started Guide | © National Instruments | 5
2. (Recommended) Install the latest service pack for LabVIEW and any LabVIEW modules
you are using.
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.
Note The default installation installs NI-RFmx, NI-RFSA, and NI-RFSG.
5. When the installer completes, select Restart in the dialog box that prompts you to restart,
shut down, or restart later.
Installing the PXIe-5840
Caution To prevent damage to the device caused by ESD or contamination, handle
the device 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-5840 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 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. If the chassis has multiple fan speed settings, ensure the fans are set to the highest setting.
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.

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.

12. 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.

13. Cover all empty slots with filler panels or use slot blockers to maximize cooling air flow.
Note Proper airflow is critical to device operation.
14. Power on the chassis.
Direct Connections to the PXIe-5840
The PXIe-5840 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-5840 to avoid
damaging the device.
Caution Apply external signals only while the PXIe-5840 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-5840 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-5840 RF IN connector, ensure that the device cannot generate signal transients
greater than the RF and DC specifications of the PXIe-5840 RF IN connector.
