All 21 USRPs installed in the FIT/CorteXlab room are of type NI-2932 (equivalent USRP N210 with a SBX daughterboard). Here are the main characteristics of the installed USRPs:

  • Frequency range: 400 MHz to 4.4 GHz
  • Maximum bandwidth: 20 MHz (but in practice less than 20 MHz are usable without loss of samples due to either the gigabit ethernet connectivity or the computing power of the signal processing computer)
  • Full-duplex TX and RX chains. There are antennas connected to the TX/RX and RX2 ports of all USRPs. In the case the TX/RX ports are used, then only half-duplex is supported
  • Synchronization: All USRPs are connected to a stack of octoclocks (see below for more info) and can be configured to work in synchronized mode by selecting external clock source in the USRP sink or source configuration.

For more details refer to the specifications page at NI.
