The ideal companion to HPs noise figure meter and systems is the HP 346 family of noise sources. Since they are broadband (10 MHz to either 18 or 26.5 GHz) , they eliminate the necessity for several sources at different frequency bands. Each source has individually-calibrated ENR values at specific frequencies. The calibration is printed on its label for easy loading into the HP 8970B . The low SWR of each noise source reduces a major source of measurement uncertainty – reflections of test signals. In addition, the variety of available connectors reduces the need for degrading accuracy with connector adapters.

The HP 346 family of noise sources are designed for a broad range of measurement applications. The 346C covers the broadest frequency range 10MHz to 26.5 GHz. The HP 346B is high ENR, low SWR, and variety of connectors make it a general-purpose noise source. The HP 346A is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers). Its very small change in reflection coefficient (< 0.01 ) from ON to OFF minimizes errors when measuring noise figure and gain as a function of input impedance.
