The new CNG-1-800/2700 covers 800 to 2700 MHz, with the same accuracy as our 70/140 MHz units! In the CNG-1-800/2700, noise generation, attenuation, and power measurements are done at IF, so there is no degradation to ratio accuracy. Total noise bandwidth is 125 MHz, wide enough for virtually every application while still providing a high noise power spectral density.
