RDS PS Data test (Tuner-1 Tuner-2)
This test checks alarms and traps on a Radio with PS=”ABCRADIO” tuned on frequency 100.5MHz.
The test was carried out on both tuners.
In static mode we have set PS Ref Mask1 to “KRADIO” and we leave default values on Ref Mask2 up to Ref Mask4
(********) and CharRef=*, a Timeout of 30 sec and an Hold Time of 20 sec as in fig. above.
The system need to find a match between received PS and ALL of not empty Ref Masks no later than Timeout,
otherwise an alarm condition raises.
PS Ref Masks (like PI) accepts wildcards and wildcard character is shown by CharRef field. Of course this character can
be modified by user. Note that Ref Masks can be 1 to 8 chars long. If a Ref Mask is shorter than 8 chars a sub-string
search is performed on received PS. Also note that a Ref Mask formed by 8 wildcards will match anyway.
Instead if the Timeout is equal to zero only PS variations will be searched for having a valid condition
In this case an alarm condition raises up because system search a match for Ref1 substring (KRADIO) into PS.
Under the alarm condition the RDS alarm led (we have associated the PS 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”).
