5. 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.
6. Power on the PXI Express chassis and controller system.
7. Verify that the ACCESS LED is on for all modules.

Direct Connections to the NI 5601
The NI 5601 is a precision RF instrument that is sensitive to ESD and transients. Ensure you
are making proper direct connections to the NI 5601 to avoid damaging the device.
Caution
Apply external signals only while the NI 5601 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 5601 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 5601
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 5601 RF IN
connector.
