HP 346C Noise Source, 10 MHz to 26.5 GHz

The ideal companion to HP's noise figure meter and systems is the HP 346C noise source. Since it is broadband (10 MHz to 26.5 GHz), it eliminates the necessity for several sources at different frequency bands. It has an individually calibrated ENR value at specific frequencies. The calibration is printed on its label for easy loading into the HP 8970B. The low SWR of the noise source reduces a major source of measurement uncertainty, reflections of test signals. Option K01 is a coaxial noise source and features coverage from 1 to 50 GHz with the 2.4 mm coaxial connector and can be added to the HP 346B.
