Calibrated Noise Sources
Mercury Systems calibrated noise sources are designed in frequency ranges from10 MHz to 40 GHz. The NS 346 series noise sources are specifically crafted to
be used with noise figure meters. They are factory calibrated to a gold standard calibration. These noise sources also have extremely good match in both
on and off states which increases the accuracy of the noise figure measurement.
Gold Standard Calibration and Quality Assurance:
Accuracy: Each noise source is accurately calibrated at Mercury's state of the art metrology lab using a reference noise that has been directly calibrated by the National Physical Laboratory in England (NPL)*. This reference noise source is known as a gold standard. Mercury offers:
- More calibration points across the spectrum
- Special discrete calibration frequencies
