National Instruments 783151-01 Software Defined Radio Device

The National Instruments 783151-01, also known as model USRP-2952R, is a Software Defined Radio (SDR) device designed for high performance applications. It can operate within a frequency range of 400 MHz to 4.4 GHz and supports both transmission and reception over two channels. This SDR device is well suited for applications requiring high precision frequency tuning, synchronization and real time processing. The 783151-01 device is built with GPS-disciplined oscillator (GPSDO) which enables synchronization to a GPS reference signal. Accurate timing, location monitoring, and clock synchronization are made possible by this function. When not locked to GPS, the oscillator's frequency accuracy is 25 ppb; when locked, it increases to 5 ppb.

The transmitter of the NI 783151-01 device has an output power range of 50 mW to 100 mW (17 dBm to 20 dBm) and a gain range of 0 dB to 31.5 dB, which may be adjusted in 0.5 dB steps. This adaptability makes it possible to precisely regulate signal strength. The model has a maximum instantaneous real-time bandwidth of 40 MHz or 120 MHz. This is contingent upon the setup that accommodates a broad spectrum of signal bandwidths for a variety of applications. The input voltage range for the 783151-01 is 9 V to 16 V DC, and its usual power consumption is 38 W to 44 W. 1,024 MB of onboard DRAM is available on the device to facilitate data-intensive operations. It weighs 1.588 kg and has dimensions of 26.67 cm by 4.06 cm by 21.84 cm.

The model can function within a temperature range of 23 °C ± 5 °C and a non-condensing relative humidity range of 10% to 90%. In addition, the highest altitude at which it has been tested is 2,000 meters. This SDR also features two channels and covers the same 400 MHz to 4.4 GHz frequency range on the receiver side. It has a gain range of 0 dB to 37.5 dB, with 0.5 dB steps for precise adjustments. The receiver's maximum input power is -15 dBm, and it operates with a low noise figure of 5 dB to 7 dB. The device's Analog-to-Digital Converter (ADC) resolution is 14-bit with a spurious-free dynamic range (SFDR) of 88 dB.
