The NI 5646R-G 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 5646R-G to avoid damaging the device.

Note Do not apply external signals to the NI 5646R-G output ports. Applying external signals may cause damage.
  • Ensure you are properly grounded when manipulating cables or antennas connected to the NI 5646R-G.
  • 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 NI 5646R-G, ensure no signal transients are sourced to the NI 5646R-G.
