描述:

To ensure the operation of TOFD technology, in some cases the use of long (over 5 m) high-frequency cables is required. At the same time, normative documents require an acceptable noise level to isolate diffraction signals against a background of noise.

概观:

In order for the noise level to be acceptable, a preamplifier with a fixed gain is used.
