The NoiseCom PNG7110 is a precision noise generator that produces additive white Gaussian noise (AWGN) for injection into RF signals across a broad frequency range. It combines an internally generated noise source with user-supplied input signals in a low-distortion summing path, delivering repeatable noise levels essential for BER, SNR, and CNR testing. The instrument offers fine-grain attenuation control with exceptional accuracy and includes a summing input for signal-to-noise ratio applications.
