Test charts are used to test digital cameras and to perform objective measurements. But there are certain aspects in testing a camera that require a real scene. One of these aspects is the correct white balancing for different types of illuminants. Another aspect might be the determination of the visual loss of detail due to noise reduction or the amount of noise in an image.

Noise Source, 10 MHz to 18 GHz, nominal ENR 15 dB
346B
-
The Keysight 346B noise source is the ideal companion to Keysight'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 346B's high ENR, low SWR, and variety of connectors make it a general-purpose noise source. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.
