Levels in dBm0, relative levels
(REL)
Level in dBm0 = Absolute level - Level in dBr.

Level plan for a transmission system
At the 0 TLP (0 dBr point) the level in dBm0 is equal to the
absolute power level. For other points in the transmission
system, [dBm0] = [dBm] - [dBr]. It must be ensured that the
correct relative level and the correct input impedance are
used for other test points.
