This operating mode has not available the offset
option.
Frequency mode operation
The display will show, either the Video Carrier
frequency (for analog signals) or the central
frequency of the channel (for digital signals).
Output frequency values range from 47 to 862
MHz.
To modify parameters, scroll through the menu by

(long press).
b. Configuration Menu 2
This menu allows to select one of the two
possible processor operating modes: Amplifier or

In the
Converter option, output frequency is not
equal to input frequency, and therefore are shown
both output and input menus
