• Automatic upload of ENR data to the analyzers via USB connection significantly speeds up the overall setup time
  • Electronic storage of Excess Noise Ratio (ENR) calibration data decreases opportunity for user error
  • Temperature sensing improves measurement accuracy, leading to tighter specification of device performance

The U1831C is a versatile USB-powered smart noise source. The USB connection significantly reduces setup time and provides compatibility with noise figure analyzers and signal analyzers. The broadband noise source accurately measures noise figures from 10 MHz to 26.5 GHz.
