1.
Connect the cable center pin on the SMA cable to the SMA connector on the appropriate
device.
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. If the SMA cable does not exactly align with the
SMA connector, bend the cable slightly by hand to align the cable and the
connector. The amount of bending should be minimal. The cables can be
damaged by excessive bending.
2.
Hand-tighten the SMA cable end on the SMA connector 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 repeat step 1 before continuing with this step.
3.
Use an appropriate torque wrench or torque screwdriver and SMA driver bit (not
included) to complete the tightening of the SMA cable to 1 N · m. Rotate the torque
wrench no more than one revolution to tighten the SMA cable before reaching maximum
torque.

Direct Connections to the PXIe-5654
The PXIe-5654 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-5654 to avoid
damaging the device.
Note
Do not apply external signals to the PXIe-5654. Applying external signals
may cause damage.
•
Ensure you are properly grounded when manipulating cables or antennas connected to the
PXIe-5654.
•
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-5654, ensure no signal transients are sourced to the PXIe-5654.
