ADJUSTMENT REMOTE COMMANDER
The adjustment remote commander is used for changing the
calculation coefficient in signal processing, EVR data, etc. The
adjustment remote commander performs bi-directional
communication with the unit using the remote commander signal
line (LANC). The resultant data of this bi-directional communication
is written in the non-volatile memory.

DATA PROCESS
The calculation of the DDS display and the adjustment remote
commander display data (hexadecimal notation) are required for
obtaining the adjustment data of some adjustment items. In this case,
after converting the hexadecimal notation to decimal notation,
calculate and convert the result to hexadecimal notation, and use it
as the adjustment data. Indicates the hexadecimal-decimal
conversion table.
