| TECHNICAL APPENDIX 180
Tested in Scan mode with 3 frequencies:
F1: 100.5 MHz
F2: 95.3 MHz
F3: 96.7 MHz
and two PS Ref Mask: “KRADIO” and “ABC” as depicted below.
Timeout = 30 sec. Hold Time = 10 sec.
In Scan Mode system perform a time-division cyclical check on selected radios (see Settings->Tuner1->Last Channel
Scanning Index or alter ego for Tuner 2). It starts from Chan 1 and rests for the setted Scan Time related to channel
before pass away. If an alarm condition (or more of them) is found, it will be signaled (and
– if enabled – a trap is
launched).
Now system search a match on Chan1 PS (ABCRADIO) w
ith two Refs (substring “KRADIO” and substring “ABC”).
PS Ref Mask2 content will match (“ABC” is a substring of “ABCRADIO”) but Ref Mask1 will not, so an error condition will
raises up.
The traps will be sent in the instant the alarm rises up, but PS and the time in the var-binds will be related to the moment
the Timeout is expired.
Under the alarm condition the RDS alarm led on the panel must be on (flashing if the alarms are more than one on the
channel list) and clicking on the channel number of the
correspondent tuner the RDS error will be displayed (“RDS
DATA”).
In case of more errors on the related channel, they will rotate for about 30 seconds in a sequence carousel.
Tested in SmartScan with the same setup depicted above for ‘normal’ Scan Mode.
Scan Mode is an evolution of normal Scan Mode that rigidly cycles between selected Channels.
If an alarm condition is found on a channel, instead of state an alarm condition, system stops on channel for a period
(depending on tested service that cause alarm condition) collecting more data. In this state no alarm or Trap was
reported. The Channel Memory index reports the cause(s) of the stop (see below: “1 of 3 (PS)”).
