USRP-2950 Specifications

USRP-2950 Specifications

These specifications apply to the USRP-2950 40 MHz Software Defined Radio Device and the USRP-2950 120 MHz Software Defined Radio Device. When not otherwise specified, the specifications for the USRP-2950 in this document refer to both the USRP-2950 40 MHz and the USRP-2950 120 MHz. The USRP-2950 contains a GPS-disciplined oscillator (GPSDO), which enables you to lock the internal clocks to a GPS reference signal, synchronize using GPS timing information, and query GPS location information.

Note NI recommends periodically locking the GPS for at least 1 hour to recalibrate the GPSDO module accuracy.

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Characteristics unless otherwise noted.

Conditions

Specifications are valid at 25 °C unless otherwise noted.
