Direct Connections to the Device

The USRP device is a precision RF instrument that is sensitive to ESD and transients. Ensure you take the following precautions when making direct connections to the USRP device to avoid damaging the device.

Notice Apply external signals only while the USRP device 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 device 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 device 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 device TX 1 RX 1 or RX 2 connector.
