National Instruments 783924-01

The National Instruments 783924-01 (Model Name: USRP-2942R) is a sophisticated software-defined radio (SDR) device, purposefully designed for wireless communication research and prototyping applications. With a frequency range spanning from 400 MHz to 4.4 GHz, this versatile device is suitable for a wide array of tasks, including mobile communications, satellite links, and radio astronomy. The SDR features dual transmitter and receiver channels, facilitating real-time processing capabilities. The receiver offers a gain range from 0 to 37.5 dB and can handle input signals up to -15 dBm, while maintaining a low noise figure between 5 to 7 dB. The maximum real-time bandwidth is configurable up to 120 MHz, supported by a 14-bit analog-to-digital converter (ADC) that provides high-precision signal digitization with a spurious-free dynamic range (SFDR) of 88 dB.

On the transmitter side, the device features a frequency step of less than 1 kHz and delivers output power levels between 50 mW and 100 mW, with gain adjustments available in increments of 0.5 dB up to 31.5 dB for precise modulation and output power management. The maximum instantaneous real-time bandwidth is 40 MHz, expandable up to 120 MHz based on configuration. Accurate signal generation is ensured by a 16-bit digital-to-analog converter (DAC) with an SFDR of 80 dB. The USRP-2942R operates on a DC power supply with an input voltage range of 9 V to 16 V, consuming between 38 W and 44 W. It boasts 1 GB of onboard DRAM for efficient data handling and real-time processing. Compact and lightweight, the device measures 26.67 cm x 4.06 cm x 21.84 cm and weighs 1.588 kg. Designed for indoor use, it operates optimally within an ambient temperature range of 23 °C ± 5 °C and tolerates relative humidity from 10% to 90% (non-condensing). The 783924-01 meets several international safety and electromagnetic compatibility standards, including IEC 61010-1 and EN 61326-1, ensuring reliability in various research environments.
