Calibrated Noise Sources
NC3400 Series
The NC3400 Series coaxial AWGN noise sources are an excellent choice for applications requiring high ENR and immunity to large incident RF power, such as ATE, radiometer, and radar systems. The calibration accuracy and flatness of the NC3400 Series noise sources are enhanced by their low VSWR. The built-in isolator provides almost constant output impedance as the noise source bias is switched on and off. The isolator also protects the noise diode from incident RF power (consult the factory for higherpower units).
An SMA female connector is standard for the RF output and a BNC female connector is standard for the bias input. Other connectors are available as options.
