After the adjustment has been terminated, the operating software starts automatically and the CRTU
Radio Unit is ready for use and complies with the specifications, except for the high-precision level

In order to achieve the level accuracy as described in the data sheet, a so-called path error data record
is necessary.
To this end, the CRTU Radio Unit must be measured using the test system ACS 100 (see chapter 1,
