DEVICE SPECIFICATIONS NI USRP™-2953R 1.2 GHz to 6 GHz Tunable RF Transceiver This document lists specifications for the NI USRP-2953R (NI 2953R) universal software radio peripheral (USRP). The NI 2953R 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. All characteristics described in this document are based on the manufacturing design. This equipment information is only for product description and is not covered by warranty. The NI 2953R is not a calibrated device. Typical values describe useful product performance that are not covered by warranty. Typical values may not be verified on all units shipped from the factory. Unless otherwise noted, typical values cover the expected performance of units over ambient temperature ranges of 23 °C ± 5 °C with a 90% confidence level, based on measurements taken during development or production. Note All numeric characteristics are typical unless otherwise noted. Specifications are subject to change without notice. For the most recent NI 2953R specifications, visit ni.com/manuals. To access NI 2953R documentation, navigate to Start»All Programs»National Instruments» NI-USRP»Documentation. Caution Do not operate the NI 2953R in a manner not specified in this document. Product misuse can result in a hazard. You can compromise the safety protection built into the product if the product is damaged in any way. If the product is damaged, return it to National Instruments for repair.
