User Correction (Ucor)
The "User correction" function can be used to create and activate lists in which level correction values
are assigned to arbitrary RF frequencies.
Up to 10 lists with a total of 160 correction values can be compiled. For frequencies not included in the
list, level correction values are determined by interpolation based on the nearest correction values.
When user correction is switched on, Ucor (user correction) is displayed in the header field in addition to
the level. The RF output level is the sum of both values.
Level + Ucor = output level
If an offset is selected at the same time, the displayed level value is the difference between the
amplitude and the offset entered in the Level menu.
Amplitude offset = level
User correction is active in all operating modes when switched on.
