Calibrated Noise Sources

NC346 Series
 Broadband Precision Calibrated Noise Sources

Noise Com's NC346 Series is designed for precision noise figure measurement applications. The VSWR has been improved, reducing multiple reflections of the test signals and significantly increasing the measurement accuracy of most noise figure set-ups.

The NC346 Series noise sources have broadband coverage and extremely good temperature and voltage stability, for the finest noise figure meter-compatible laboratory standards.

NC3000 Series
Calibrated Coaxial Noise Sources

Noisecom's NC 3000 Series calibrated coaxial noise 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 NC 3000 Series includes the NC 3100 units with 15 dB ENR output for noise-figure meters, and the NC 3200 Series high-output noise sources with outputs between 26 and 35 dB ENR for radar and satellite communications system testing.

Features

  • Noise output rise and fall times less than 1 μs.
  • VSWR as low as 1.35:1.
  • Noise output variation < 0.01 dB/°C, and < 0.1 dB/1%ΔV.
  • Input power +28 VDC at 30 mA max.

NC3400 Series
High ENR Coaxial Noise Sources

The NC3400 Series coaxial 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.

Applications

  • Radar systems
  • High NF device measurements
  • Automated test equipment (ATE)

NC5000 Series
 Precision Calibrated Millimeter-Wave Noise Sources

The NC5000 Series noise sources feature outstanding stability, switching speed, and ripple-free response over standard waveguide bands. The high stability of the NC5000 Series allows these units to be used in place of cumbersome gas tube noise sources.
