Direct Connections to the NI 5698
The NI 5698 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 5698 to avoid
damaging the device.
Caution
Apply external signals only while the NI 5698 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 5698 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 5698
RF IN connector, ensure that the device cannot generate signal transients greater than the
RF and DC specifications of the NI 5698 RF IN connector.
