Excellent temperature and voltage stability Units for noise figure meters feature 15.5-dB ± 0.75 dB ENR output High-output units for radar and satellite communications system testing feature output between 26 and 35 dB ± 1 dB ENR

Ideal for applications requiring high ENR and immunity to large incident RF power Low VSWR Built-in isolator 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).

Broadband coverage Extremely good temperature stability Superior voltage stability Noise figure meter-compatible The NC346 Series is designed for precision noise figure measurement applications. Each module’s low VSWR reduces multiple reflections and significantly increases the measurement accuracy for most noise figure test configurations.

High ENR Wide frequency range Custom frequencies available The NC3600 Series coaxial noise sources are an excellent choice for applications requiring high ENR, such as ATE, radiometer, and radar systems. An SMA male connector is standard for the RF output and feed thrus for bias input. SMA female is an option. Custom frequencies and flatness available. Contact the factory with your request.

Outstanding stability Fast switching speed Ripple-free response over standard waveguide bands The NC5000A Series AWGN noise sources feature outstanding stability, switching speed, and ripple-free response over standard waveguide bands. The high stability of the NC5000A Series allows these units to be used in place of cumbersome gas tube noise sources. Ripple in the output of noise sources has a direct effect on measurement accuracy, so Noisecom has tailored the response of the NC5000A Series so that ripple is minimized throughout the specified frequency range.
