RDS PI Data test (Tuner-1 Tuner-2)
This test checks alarms and traps on a Radio with PI=5215 tuned on frequency 100.5MHz.
The test was carried out on both tuners.
In Static mode we have set a PI Ref Mask to 5000 with Validation time and Hold time equal to 10 sec. (see fig. below)
The system checks for a match between any not empty Ref Masks and received PI. If at least one of them matches OK
condition is true, otherwise an alarm condition raises.
In this case there is
an alarm condition (received PI=5215 won’t match with PI Ref1=5000).
Under the alarm condition the RDS alarm led (we have associated the PI 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
and two Pi Ref Mask: 5000 and 51** (we have used wildcards) as depicted below.
Validation Time = 15 sec. Hold Time = 10 sec.
For this test we’ve added PI Ref Mask2=51**. Now system search for a PI=5000 or a PI from 5100 up to 51FF.
Received PI=5215 don’t match any PI Ref so an alarm condition raises.
