Alternative Frequency Lists
Alternative frequency lists can be transmitted in two ways:
Method A: The frequencies of an AF list are entered one after the other; the frequency currently
transmitted has to be specified as the first frequency.
Method B: The frequencies of an AF list are entered in pairs, each pair containing the frequency
currently transmitted and an alternative frequency. The frequency pairs should normally be
entered in ascending order. Descending order should be chosen only if the alternative
frequencies belong to different regions or are used to broadcast different programs at
different times.
Note: Do not combine methods A and B!
Method A:
 Generate a new alternative frequency list with
STEReo:DIRect “AF=N,87.6,87.7,87.8“.
 Set the group sequence, e.g.
STEReo:DIRect "gs=0A,14A".
The group sequence must contain group 0A.
The alternative frequencies are now transmitted in group 0A.
 Add another alternative frequency list with
STEReo:DIRect “AF=+,88.6,88.7,88.8“
Method B
 Generate a new alternative frequency list with
STEReo:DIRect “AF=N,87.6,90.2,87.6,90.2“.
 Set the group sequence, e.g.
STEReo:DIRect "gs=0A,14A".
The group sequence must contain group 0A
he alternative frequencies are now transmitted in group 0A.
 Add another alternative frequency list with
STEReo:DIRect “AF=+,88.6,91.2,88.6,91.2“
The frequency lists are not checked for correctness. For this reason, make sure that the syntax is
correct.
A maximum of five AF lists can be generated. For type A lists, max. 25 frequencies per list can be
specified, for type B lists, max. 12 frequencies per list.

Creating an EON data set:
 Read the list of existing EON data sets with
STEReo:DIRect? "eon-pi"
The list shows the EON PI codes already used and those remaining for new data sets.
 Create an EON data set with
STEReo:DIRect "eon-pi=1234"
 Set the program service (PS) name for the EON data set with
STEReo:DIRect "EON-PS=1234,TEST EON"
