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

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.
