The 346B 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.
- Frequency range: 10 MHz to 18 GHz
- VSWR: < 1.3:1
- Nominal ENR 15 dB
- Low SWR for reducing noise figure (NF) measurement uncertainty
- Individually calibrated ENR values at specific frequencies to enhance accuracy
Since the 346B is broadband, it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The Agilent 346B's high ENR, low SWR, and variety of connectors make it a general-purpose noise source.
