P.9.21 / uint32 Selects frequency reference source 2.
For the selections, and a diagram of reference source
selection, see parameter
28.11 Frequency ref1 source .
Frequency ref2
source 28.12
Ref1 / uint16 Selects a mathematical function between the reference
sources selected by parameters
28.11 Frequency ref1
source and 28.12 Frequency ref2 source . See diagram
at 28.11 Frequency ref1 source .
Frequency ref1
function 28.13
0 Signal selected by 28.11 Frequency ref1 source is used
as frequency reference 1 as such (no function applied).
Ref1
1 The sum of the reference sources is used as frequency
reference 1. Add (ref1 + ref2)
2 The subtraction ([ 28.11 Frequency ref1 source ] - [ 28.12
Frequency ref2 source ]) of the reference sources is used
as frequency reference 1.
Sub (ref1 - ref2)
3 The multiplication of the reference sources is used as
frequency reference 1. Mul (ref1 x ref2)
4 The smaller of the reference sources is used as
frequency reference 1. Min (ref1, ref2)
5 The greater of the reference sources is used as
frequency reference 1. Max (ref1, ref2)
