• 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

The NC3000 Series calibrated coaxial AWGN sources are well suited for receiver testing, noise figure measurements, or applications that require broadband noise and fast switching times. Several models include output isolators, and voltage regulators that provide excellent stability over varying temperature and voltage ranges. The NC3000 Series includes the NC3100 units with 15 dB ENR output for noise-figure meters, and the NC3200 Series high-output noise sources with outputs between 26 and 35 dB ENR for radar and satellite communications system testing.

• 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).

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.

• 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.
