REF<x>:SELect
Sets or returns the selected channel within the reference group. This command is
similar to setting Selected Channel in the Group Definition menu. The logic
scope highlights the selected channel in the group. When automated measure-
ments are implemented, the logic scope makes the measurement on the selected
channel within the selected group. The selected channel must fall between the
first channel and last channel, inclusively.
