Re: UT
Reference level is the % FSH/ dBs at which you set youtr reference echo. Could be Backwall to 100% FSH.
Scanning dBs are generally 6 dBs greater thanthe Reference\echo. Usually it is written in the standards as do scanning at RE+6 dBs or 10 dBs or 20 dBs.

TOPAZ® 64: Fully Integrated Portable 64 Channel PAUT Instrument with FMC & TFM

Introducing TOPAZ64, the industry’s most intelligent fully integrated, portable 64-channel phased
...
array ultrasound (UT) instrument. TOPAZ64 combines code-compliant phased array UT with the industry’s most advanced full matrix capture (FMC) and total focusing method (TFM) capabilities. Featuring the highest acquisition frequency in its class, high resolution FMC and a 12” multi-touchscreen, users can easily visualize even the smallest flaws. TOPAZ64 can generate a bipolar pulse that provides more acoustic energy versus previous models for punching through thick components. The result is a portable tool that delivers increased inspection coverage, more accurate signals, and the ability to handle all UT inspections in one package. TOPAZ64 is ideal for challenging applications in transportation, oil and gas, manufacturing and power generation.
