service.
Note Refer to the NI PXIe-5667 (3.6 GHz) Specifications at ni.com/manuals for
complete specifications.
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.
4| ni.com | NI PXIe-5667 (3.6 GHz) Getting Started Guide

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 5667
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 NI-RFSA 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.
To use the included cables, you must install the NI 5694 IF conditioning module immediately
to the left of the NI 5603 RF downconverter module, the NI 5622 IF digitizer module
immediately to the left of the NI 5694 module, the NI 5653 LO source module immediately to
the right of the NI 5603 RF downconverter module, and the NI 5693 RF preselector module
immediately to the right of the NI 5653 module.
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.

3. Using the long semi-rigid SMA-to-SMA coaxial cable (labeled P), connect the RF IN
connector on the NI 5603 front panel to the RF OUT connector on the NI 5693 front
panel.
4. Using the flexible RF SMA-to-SMA coaxial cable, connect the CLK IN connector on the
NI 5622 front panel to the REF OUT 100 MHz connector on the NI 5653 front panel.
5. Using the flexible RF SMA-to-SMA coaxial cable, connect the REF/LO IN connector on
the NI 5694 front panel to the REF OUT 10 MHz connector on the NI 5653 front panel.
6. Using the three medium semi-rigid SMA-to-SMA coaxial cables (labeled J), connect the
LO1, LO2, and LO3 connectors on the NI 5653 front panel to the associated LO1 IN,
LO2 IN, and LO3 IN connectors on the NI 5603 front panel.
7. Hand-tighten all SMA cable ends on the SMA connectors after the cable center pins are
correctly aligned and connected. The cable connectors should tighten without much
torque or effort. If a cable bends due to incorrect alignment, remove the cable from the
front panel connector and reconnect the cable center pin on the SMA cable to the SMA
connector.
8. Carefully complete tightening all SMA connectors to 1 N · m using an appropriate torque
wrench (not included) or torque screwdriver and SMA driver bit. Tighten only until the
wrench clicks.
Caution Incorrect torque at SMA connections can degrade signal fidelity and
phase-locked loop (PLL) performance and may cause insertion loss. Use an
appropriate torque wrench or torque screwdriver and SMA driver bit to ensure
all SMA connections are properly torqued. SMA connectors for connections to
external equipment may require torque different from 1 N · m, depending on
the connector type, material, and manufacturer.
9. Power on the PXI Express chassis and controller system.
10. Verify that the ACCESS LED is on for all modules.

8| ni.com | NI PXIe-5667 (3.6 GHz) Getting Started Guide

Caution Apply external signals only while the NI 5603 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 5603 RF 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 5603
RF 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 5603 RF IN
connector.

This connector is the output terminal for the LO1 (3.2 GHz to 8.3 GHz)
source. LO1 OUT is an SMA connector with an impedance of 50 Ω
(nominal).
LO2 Connects to the LO2 IN connector on the NI 5603 module front panel.
This connector is the output terminal for the LO2 (4 GHz) source.
LO2 OUT is an SMA connector with an impedance of 50 Ω (nominal).
LO3 Connects to the LO3 IN connector on the NI 5603 module front panel.
This connector is the output terminal for the LO3 (800 MHz) source.
LO3 OUT is an SMA connector with an impedance of 50 Ω (nominal).

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 state of the module.
OFF—The module is not generating a signal.
AMBER—The module phased-locked loops (PLLs) are attempting to lock.
GREEN—The module is generating a signal; applicable PLLs are locked.
RED—The module has detected an error state. An error state may indicate the
module detects a PLL lock failure, is exceeding approved operating temperature
and is in a state of thermal shutdown, or the module detects a power supply
failure. If the power supply fails, contact NI technical support.
Note The NI 5653 LO source has 10 MHz and 100 MHz reference outputs. For
best performance, connect the 100 MHz REF OUT connector to the NI 5622
CLK IN connector.
