2.5.7 Specifying Behavior on Failure of a Reference Source
1. Select Exciter A ATSC > Reference.
The Reference window opens.
2. Select the required settings.
The table below describes the adjustable parameters in detail:
RF Slope Correction of a slope of the amplitude frequency response in the spec-
trum for equalizing subsequent components (output stage, filter).
Modulation Slope Correction of a curvature of the amplitude frequency response in the
spectrum for equalizing subsequent components (output stage, filter).
Display Description
AGC Regulation Displays the level of the output level control
Setting item Explanation
Reference Selects the reference frequency source. The following settings are pos-
sible:
– Internal: operation without external reference frequency source
– External 5 MHz: operation with external 5 MHz reference on
– External 10 MHz: Operation with an external 10 MHz reference
– External 1pps: Operation with an external time reference (1 pps)
The same setting options are available in menu window RF > Synthe-
sizer.
