The NC8107 Noise Source contains a precision white Gaussian noise source with an output frequency range of 250 kHz to 100 MHz. The NC8107 noise source is integrated with an amplifier, a 10 dB 1 dB/step attenuator, and power supply. The NC8107 has a 50 ohm output impedance and a 1 watt output. A signal combiner input, a choice of step attenuators, 75 Ohm output impedance, rack mount flanges, and type N or BNC output connectors are optionally available.
