The NoiseCom UFX7111 is a precision white Gaussian noise generator engineered for RF testing, communication system evaluation, and signal integrity assessment. Operating across 1 GHz to 2 GHz, it delivers calibrated noise output with ±1.5 dB flatness and typical power of +10 dBm/Hz. The instrument provides adjustable attenuation from 0 to 127 dB in selectable 1 dB or 0.1 dB steps, enabling controlled noise injection into test systems. A direct replacement for the NC7000 Series, the UFX7111 combines manual front-panel control with remote programmability via GPIB and Ethernet interfaces.
