RDS RT+ (Tuner-1 Tuner-2)
This test checks alarms and traps on RadioText Plus service of a Radio tuned on frequency 100.5MHz.
The test was carried out on both tuners.
The system can monitor RT+ registered groups presence on tuned radio.
It can also monitor RT+ data flow (by monitoring associated data group presence) and RT+ service registration (3A
groups with specific RT+ AID).
When RT+ data groups (usually 12A) are not received for a certain time (selectable by Timeout Data) an error condition
raises up.
Similarly when RT+ registration groups (3A) are not received for a certain time (selectable by Timeout Reg.) an error
condition raises up.
On web client RT+ field shows the service status:
If RT+ service data is correctly received (in respect of tim
eouts) RT+ field print is “OK”.
When no RT+ service is broadcasted, RT+ field print is “NO SERV”.
When no RT+ groups data are received but 3A RT+ service registration groups are broadcasted, RT+ field print is “NO
DATA”.
Finally, when no 3A RT+ service reg
istration groups are received but RT+ data groups are, RT+ field print is “NO REG”.
For the test in Static Mode we have tuned on 100.5 MHz a radio that broadcast RT+ service.
We set Data Timeout=20 sec. Group Timeout=30 sec. and Hold Time=40 sec.
Tested in Scan mode with 3 frequencies:
F1: 100.5 MHz
F2: 95.3 MHz
F3: 96.7 MHz
Data Timeout=20 sec.
– Reg. Timeout=30 sec. - Hold Time=40 sec. as depicted below.
