The National Instruments 783151-01, also designated as the USRP-2952R, is a sophisticated Software Defined Radio (SDR) device engineered for high-performance applications. This dual-channel device operates within a frequency range of 400 MHz to 4.4 GHz and facilitates both transmission and reception, catering to applications that demand high precision and real-time processing capabilities. The integrated GPS-disciplined oscillator (GPSDO) allows for synchronization to a GPS reference signal, achieving a frequency accuracy of 25 parts per billion (ppb) without GPS lock and enhancing accuracy to 5 ppb when locked. The transmitter features an output power range from 50 mW to 100 mW (17 dBm to 20 dBm) with a gain range adjustable from 0 dB to 31.5 dB in 0.5 dB increments, enabling precise signal strength control. The device supports a maximum instantaneous real-time bandwidth of either 40 MHz or 120 MHz, depending on the configuration, thus accommodating a variety of applications requiring diverse signal bandwidths.

Power is supplied through an input voltage range of 9 V to 16 V DC, with typical power consumption between 38 W and 44 W. The 783151-01 is equipped with 1,024 MB of onboard DRAM, designed to handle data-intensive tasks efficiently. This unit has a compact form factor, measuring 26.67 cm by 4.06 cm by 21.84 cm and weighing 1.588 kg. It operates effectively in temperatures ranging from 23 °C ± 5 °C and a non-condensing relative humidity of 10% to 90%, with a tested operational altitude limit of 2,000 meters. The receiver also operates within the same frequency range and features a gain range of 0 dB to 37.5 dB, adjustable in 0.5 dB steps, and a maximum input power of -15 dBm. The low noise figure ranges from 5 dB to 7 dB, and the device incorporates a 14-bit analog-to-digital converter (ADC) with a spurious-free dynamic range (SFDR) of 88 dB, ensuring high-quality signal capture and processing capabilities. The National Instruments 783151-01 is backed by a warranty of two to three years, making it a reliable choice for advanced SDR applications.
