as frequency reference 1 as such (no function applied).
The sum of the reference sources is used as frequency
reference 1.
The subtraction ([28.11 Frequency ref1
Frequency ref2 source]) of the reference sources is used
as frequency reference 1.
The multiplication of the reference sources is used as
frequency reference 1.
The smaller of the reference sources is used as
frequency reference 1.
The greater of the reference sources is used as
frequency reference 1.
