RDS InHouse (Tuner-1 Tuner-2)
This test checks alarms and traps on IH service of a Radio tuned on frequency 100.5MHz.
The test was carried out on both tuners.
The system can monitor IH (6A) groups presence on tuned radio.
It can also monitor IH data flow (by monitoring content variations).
When 6A groups are not received for a certain time (selectable by Group Timeout) an error condition raises up.
If carried data don’t change for a certain time (selectable by Data Timeout) an error condition raises up.
On web client IH field shows the service status:
If 6A
groups are correctly received and data content changes (in respect of timeouts) IH field print is “OK”.
When no IH service is broadcasted or the time between 6A groups exceeds Timeout, IH field print is “NO SERV”.
When IH data content don’t change before Timeout, IH field print is “NO DATA”.
For the Static Mode test we set Data Timeout=20 sec. Group Timeout=30 sec. and Hold Time=15 sec.
Under the alarm condition the RDS alarm led on (we have associated the IH alarm to the panel led Rds error) on the
panel must be on (not flashing) and clicking on the channel number of the correspondent tuner the RDS error will be
displayed (“RDS DATA”).
Tested in Scan mode with 3 frequencies:
F1: 100.5 MHz
F2: 95.3 MHz
F3: 96.7 MHz
Data Timeout=20 sec. - Group Timeout=30 sec. - Hold Time=15 sec. as depicted below.
