k346 Series – 0.01GHz to 67GHz
Precision calibrated coaxial noise sources engineered for accurate noise figure measurements across broadband RF, microwave and millimeter-wave frequencies.
Broadband Calibrated Coaxial Noise Source
kTB k346 Series Broadband Calibrated Coaxial Noise Sources are designed for precision noise figure measurement applications, offering exceptional accuracy and reliability.
With low VSWR, they significantly reduce multiple reflections, enhancing measurement accuracy and minimizing uncertainty.
Each unit includes calibrated ENR reports traceable to NIST and VSWR on/off data, with flatness better than ±1.0 dB across the specified frequency range.
Standard operation requires +28Vdc with a maximum current draw of 30mA, while custom voltage, output levels and frequency ranges are also available.
