HP/Agilent 346A Noise Source， 10 MHz to 18 GHz， nominal ENR 6 dB
 
Description
The HP/Agilent 346A noise source is the ideal companion to Agilent‘s noise figure solutions. Since it is broadband (10 MHz to 18 GHz)， 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 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).
