The 346A is a used 18 GHz Noise Generator from Agilent. A noise signal generator is a type of electronic test equipment that produces a noise, or random signal, to test an electronic product’s frequency response, noise figure, and other important parameters.
- Low SWR for reducing noise figure measurement uncertainty
- Individually calibrated ENR values at specific frequencies
- Calibration supplied on floppy disk for easy loading into NFA-series noise figure analyzers
The Agilent 346A eliminates the necessity for several sources at different frequency bands. The low SWR of the Agilent noise source reduces a major source of measurement uncertainty; reflections of test signals. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers.
