FUNCtion{1|2|3|4}:SUBTract <character_data>,<character_data>
[,<numeric_value>]
This command performs the subtraction operation on the specified channel pair.
FUNCtion1 to FUNCtion4 represents the first to the fourth subtraction operation
respectively.
– The result of the subtraction will be displayed as an additional trace on the
