NI USRP-2953R Tunable RF Transceiver
The NI USRP-2953R tunable RF transceiver functions as a software defined radio platform. It integrates dual channel transmission and reception within a single compact architecture. The unit supports real time processing for demanding wireless communication research environments. The USRP-2953R transceiver has a transmitter section that provides two independent output channels. In terms of frequency, the operational range is from 1.2 GHz to 6 GHz, while the tuning resolution is finer than 1 kHz for precise carrier generation.
The transmitter's output power ranges from 50 mW to 100 mW between 1.2 GHz and 3.5 GHz. Within 3.5 GHz to 6 GHz the output power ranges from 5 mW to 32 mW. The maximum output levels correspond to 17 dBm to 20 dBm at lower frequencies. Higher band output levels correspond to 7 dBm to 15 dBm across the extended range. The transmitter gain is adjustable from 0 dB to 31.5 dB and gain resolution is configurable in precise 0.5 dB increments. The architecture of the USRP-2953R allows a maximum instantaneous bandwidth of 40 MHz, which can be raised up to 120 MHz with an extended configuration.
The highest I/Q sample rate for the transmitter reaches 200 MS per second. The integrated digital to analog converter provides 16-bit resolution. The spurious free dynamic range of the DAC is specified at 80 dB. These characteristics ensure accurate waveform synthesis with controlled spectral purity. The receiver section of USRP-2953R provides two coherent input channels. The receiver frequency range spans from 1.2 GHz to 6 GHz and its gain is programmable from 0 dB to 37.5 dB. The gain adjustment resolution for the unit is 0.5 dB per step. The analog to digital converter delivers 14-bit resolution. The receiver contains a spurious free dynamic range which is specified at 88 dB. This performance enables accurate digitization of wide dynamic range signals. The tunable transceiver maintains signal integrity across wide operating frequencies.
The NI USRP-2953R operates within a relative humidity range from 10% to 90%. The specified humidity range applies under noncondensing environmental conditions. The hardware architecture supports deterministic data transfer for FPGA based processing tasks.
