Installing the NI 5672
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-RFSG 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 chassis can cool the device
effectively.
To use the included cables, you must install the NI 5442 AWG module in the slot immediately
to the right of the NI 5610 RF upconverter 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.

2. Flexible SMA-to-SMB Cable
1. Using a flexible SMA-to-SMB cable, connect the INPUT connector on the NI 5610 front
panel to the CH 0 connector on the NI 5442 front panel.
Note Ensure that the SMA cable center pins properly align with the SMA
connectors to avoid bending the cable pins or damaging the front panel
connectors on the device.
2. Using a flexible SMA-to-SMB cable, connect the TO AWG CLK IN connector on the
NI 5610 front panel to the CLK IN connector on the NI 5442 front panel.
3. Hand-tighten all SMA cable ends on the SMA connectors. The cable connectors should
tighten without much torque or effort.
10 | ni.com | NI PXIe-5672 Getting Started Guide

4. Carefully complete tightening all SMA connectors to 1 N · m using an appropriate torque
wrench or torque screwdriver and SMA driver bit (not included). 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.
5. Power on your PXI/PXI Express chassis and controller system.
6. Verify that the ACCESS LED is illuminated on all modules. If an LED is not illuminated,
refer to the Troubleshooting section of this document.

Direct Connections to the NI 5672
The NI 5672 is a precision RF instrument that is sensitive to ESD and transients. Ensure you
take the following precautions when making direct connections to the NI 5672 to avoid
damaging the device.
Note Do not apply external signals to the NI 5672. Applying external signals may
cause damage.
• Ensure you are properly grounded when manipulating cables or antennas connected to the
NI 5672.
• 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 5672,
ensure no signal transients are sourced to the NI 5672.

TO AWG CLK IN Connects to the CLK IN connector on the NI 5442 AWG module
front panel.
Both connectors are output terminals for replications of the
upconverter 10 MHz frequency reference signal, which is useful for
driving other devices. Each replication is 180° out of phase with the
other. The output signal at these connectors is always on and cannot
be disabled.
10 MHz OUT
REF IN Routes an external frequency reference signal that can be propagated
to the PXI backplane. The NI 5610 can lock to this signal.
INPUT Connects to the CH 0 output on the NI 5442 AWG module front
panel.
Routes the IF signal from the NI 5442 AWG module for frequency
translation.
LOCAL OSC OUT 0 Routes the auxiliary local oscillator signal.
RF OUTPUT Routes the upconverted signal at the requested RF frequency.

Configuring the NI 5672 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-RFSG.
1. Launch MAX.
16 | ni.com | NI PXIe-5672 Getting Started Guide

2. In the configuration tree, double-click Devices and Interfaces to see the list of installed
devices.
Note If you are using the NI 5672 with the LabVIEW Real-Time Module,
expand Remote Systems. Find your target IP address or name, expand it, and
then expand Devices and Interfaces.
Installed devices appear under the name of their associated chassis.
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 device 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 NI 5672.
5. Associate the hardware modules that comprise your device.
a) Select the NI 5610 that is identified as not configured in the configuration tree.
b) In the Associated Devices section, select the appropriate module from each system
component drop-down listbox.
For the NI 5672, you must associate the NI 5610 RF upconverter module with the
NI 5442 AWG module.
c) Click Save in the MAX toolbar.
Note Module associations may be lost when you move the modules to
different chassis slots.
6. Self-test the device modules by selecting the modules in the configuration tree, and
clicking Self-Test in the MAX toolbar. Repeat this step for all modules in your NI 5672
system.
The MAX self-test performs a basic verification of hardware resources.
