HP 346A-002 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
- Individually
calibrated ENR values at specific frequencies
- Calibration printed on
its label for easy loading into HP 8970B
