HP 346A
Noise Source, 10MHz-18GHz
HP 346A Product Details
The
ideal companion to HP's noise figure solutions is the HP 346A noise source.
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).
Features:
- Low
SWR for reducing noise figure measurement uncertainty
