Direct Connections to the USRP-2974
The USRP-2974 is an RF instrument that is sensitive to ESD and transients. Ensure you take
the following precautions when making direct connections to the USRP-2974 to avoid
damaging the device.
Notice
Apply external signals only while the USRP-2974 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
USRP-2974 TX 1 RX 1 or RX 2 connector.
•
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
USRP-2974 TX 1 RX 1 or RX 2 connector, ensure that the device cannot generate signal
transients greater than the RF and DC specifications of the USRP-2974 TX 1 RX 1 or
RX 2 connector.
