Radio Frequency Overflow Artifact 
Quick Overview
Please note that there are different common names for this artifact.

Artifact Information
NAME Radio frequency overflow, data clipping
DESCRIPTION Image non-uniform
REASON Signal too intense
HELP Manually decrease of the receiver gain

The received radio frequency signal is too strong, parts of the signal get lost by converting from analog to digital, resulting in a washed out image.


Image Guidance
Auto-prescanning usually adjusts the amplification at the receiver in a way, that the received signal could be processed without any loss. Else the receiver gain must be corrected manually.
