Description

When doing FPGA measurements, I noticed that - at least for AES - we no longer have range / saturation checks for Husky. If the user chooses a gain value which is to high, the ADC will just saturate which invalidates measurements. It's pretty difficult to detect such issues without these automated checks. I am strongly in favor for re-adding them again.

Research direction

No files, tests, or entry points are named. Start by locating the Husky FPGA capture path and the AES measurement flow, then identify how gain and ADC saturation are handled. Done means range and saturation checks are restored for high-gain measurements and covered by automated checks.
