NoiseCom PNG7109 Precision Noise Generator, 10 MHz - 1.5 GHz

The NoiseCom PNG7109 Precision Noise Generator, 10 MHz - 1.5 GHz generates additive white Gaussian noise and provides a summing input to perform signal-to-noise or carrier-to-noise ratio testing capability. A key feature of this instrument is its low distortion signal path which sums the user-supplied signal with the internal precision white noise source. The signal path has a nominal insertion gain of 0 dB, with very low amplitude and phase ripple. The noise source provides an exceptionally high crest factor of 18 dB for accurate bit error rate testing, even with large carrier-to-noise (CNR) or bit energy-to-noise density (E_bN_o) ratios. With option 7 (DC instead of AC coupled) signal path, the PNG7109 can add noise directly to a digital TTL, ECL, or similar signal that operates in a 50Ω system.
