Amplitude-Correction Functions
This section describes the amplitude-correction functions in the order they are usually used.
Editing or Viewing the Amplitude-Correction ‘lhbles
Pressing COAL), More 1 of 4 ,
More 2 of 4, More 3 of 4, Amp Cor accesses the softkey
menus for creating an amplitude-correction table.
Note
(PRESET) turns amplitude-correction factors off (if it is on), but does not clear an
existing amplitude-correction table. Use PURGE AMP COR to clear an existing
amplitude-correction table.
Press Edit Amp Cor to edit an existing amplitude-correction table or, if no amplitude-
correction table currently exists, to create an amplitude-correction table.
Pressing PURGE AMP COR two times consecutively clears an existing amplitude-correction table.
Selecting the Amplitude-Correction Point
Pressing SELECT POINT specifies the amplitude-correction point to be entered or edited.
Amplitude-correction data is constructed from left to right and is created by entering
frequency and amplitude values into an amplitude-correction table. The frequency and
amplitude values specify a coordinate point from which amplitude-corrections are interpolated
(see Figure 5-13). Up to 79 points can be specified for the amplitude-corrections table.
