The Keysight (formerly Agilent) 346A broadband (10 MHz to 18 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 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). The unit has individually calibrated ENR values at specific frequencies to enhance accuracy.
