RF level The median desired RF output level per channel. For each
of the 4 channels, a small offset can be specified relative
to this level
R/W R/W
RF level offset The desired offset (-3 .. +3dB) relative to “RF level” R/W N/A
Settings status Indicates whether the modulator settings are consistent
and valid (‘ok’), or an error indication. Refer to section
