National Instruments 783149-01 Radio Device 

The part number 783149-01 from National Instruments is the identifying part number for the USRP-2944 Radio Device. This device has two transmitter channels that have a frequency range of 10 MHz to 6 GHz. The power of the signals transmitted over varying frequencies has a range between 50 mW to 100 mW for 10 MHz to 4 GHz signals while the power reduces to 5 mW to 50 mW for signals with the frequency range between 4 GHz to 6 GHz. To control the output signal's strength, the adjustable gain range of this device is between 0 dB to 31.5 dB with 0.5 dB increments. 

The 783149-01 also features two receiver channels with the same frequency range of 10 MHz to 6 GHz as the transmitter channels. The gain of the receiver can also be adjusted between 0 dB to 31.5 dB with 0.5 dB increments. The receiver channels support an instantaneous bandwidth of 160 MHz and an I/Q sample rate of up to 200 Mega samples per second. To handle complex signals and large amounts of data for operation the 783149-01 features a 1024 MB onboard DRAM that allows for swift processing of data. 

This radio device requires an input voltage of between 9 volts DC to 16 volts DC to operate while drawing a maximum current of 7.5 Amperes. The device can consume a power of anywhere between 38 Watts to 44 Watts depending on the number of channels being used, and the type of application this module is being used for. It is necessary to use an LPS or a class 2-rated power supply with the 783149-01 for safe operation. 

This device has a compact design with dimensions of 26.67 cm × 4.06 cm × 21.84 cm and weighs approximately 1.6 kg which makes it somewhat portable as well. Since the device performs complex signal processing tasks, it is recommended to use the 783149-01 in a cool place with a temperature of less than 23 degrees Celsius to avoid overheating. This device meets the EMC standards for electromagnetic compatibility standards and also complies with the IEC 61010-1, EN 61010-1, and UL 61010-1 standards.
