power delivery Test and Interlook test ?

[Lüder]

Please explaine the concept of power delivery test and interlook check.
I see it in radiated immunitiy and conducted Immunity also during start of calibration. What is performed? how to switch ON oder OFF ?

Thanks

Immunity is performing a power delivery test to check if there is a closed loop and increasing signal generator level is also generating an increased amplifier output level.
The power delivery test is thus only performed when forward and/or reflected powermeters are used in the test setup.
It is not recommended to disable this safety function and this is only possible by an underwater/advanced tweak.
