346B 18 GHz Noise Source

The Keysight 346 Seris
broadband (10 MHz to
50 GHz) noise source 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 346B’s high ENR, low SWR, and variety of connectors make it a general-purpose noise source. The unit has individually calibrated ENR values at specific frequencies to enhance accuracy.
