4. WORKING PRINCIPLE
The unit is designed to automatically monitor FM channels by comparing measurements from an internal tuner to
user-defined thresholds and reference settings. In case of failure, alarms are generated and notifications can be sent
by SNMP Traps, mail and/or syslog. The unit communicates with the outside world via the IP network It comes with a
client-server application serving as graphic user interface that makes it possible to remotely configure the unit, view
measurements and event logs as well as view real time measurements and listen to the audio of a service.
Cyclical monitoring on multiple programs for each receiver
Several receivers (from 1 to 8, depending on license) are available and each works independently of the others.
With multiple programs set on a single receiver, cyclical monitoring is done by setting the tuner successively on each
set frequency for acquisition of measurements and by then comparing the channel reference values with the newly
acquired data. Please note that measurements are collected only once per frequency which explains why a very brief
anomaly will not be detected. Each monitoring element is successively tested according to the hierarchical test order.
With this order; lower level tests will not be performed when a higher level error has been detected. This method also
prevents useless alarms from being sent.

Triggering alarms:
This status is then reevaluated with each monitoring cycle as the tests are performed again. When a measured value is
out-of-tolerance, the state switches to ‘ERROR’, but the alarm is not triggered immediately. For each parameter, the
“timeout before alarm” parameter can be configured: it represents a delay during which an error state is tolerated
before the alarm is triggered. Once this length of time has been reached, the state switches to ‘ALARM’, and
corresponding actions are then taken (notification, placement of the event in the event log…)
Switching from ‘ERROR’ to ‘NO_ERROR’ is immediate; however, it takes 2 confirmations to go from ‘ALARM’ to
‘NO_ERROR’, the test must be error free for 2 consecutive cycles.
The hysteresis is an additional factor to be taken into account before the unit returns to normal state after a ‘level’
type threshold violation. This value adjusts the triggering threshold after an alarm begins so that fluctuations near the
threshold level will not continuously trigger alarms. For instance, if we set the high level threshold at 60 and the
hysteresis at 5, the alarm activates at a level higher than 60, and stays on until the level falls below 55.
Detected error Error duration <
guard time
2 consecutive cycles Error duration >
with no error guard time
Triggering and end of a high threshold alarm
‘Intermittent alarm’ type tests detect short but frequent overshoots. A time window and a number of acceptable
overshoots during this time window must be set. For instance, if we do not want more than 5 overshoots within 2
minutes, a counter will start at the 1st overshoot. At the 6th overshoot within the 2 minute window, an alarm is
declared. The state is reinitialized when the number of overshoots within a 2 minute period is lesser than or equal to
5.

Intermittent alarms with a maximum of 4 events within the set time window
Case of alarms ‘closed by hierarchy’
When an alarm with a high hierarchical level is triggered, the state for each lower hierarchical level alarm changes to
‘CLOSED’ and a notification for ‘closed by hierarchy’ is sent. As an example, if an AFLOW alarm is active and the
RFLOW2 alarm gets triggered, an AFLOW trap is sent with an alarmStatus value of 3 (closed by hierarchy).
Inversely, when the high level alarm ends, the lower level tests that were ‘CLOSED’ return to ‘ALARM’ status.

no issue on the channel
When dealing with a series of channels, each channel is monitored for a set time (5 seconds on the example above,
with a 2 second delay before alarm).
Recorded start and end times depend in part on the monitoring cycle.
Channel 1: the error starts second 2 while the channel is monitored and ends second 16 while the channel is also
monitored. Alarm start and end times match actual times.
Channel 2: the error starts second 6 while the channel is monitored and ends second 11 when the channel is no longer
monitored. An error starts again second 18 and ends second 23. The monitoring unit cannot detect the absence of
error between second 11 and second 18. It is seen as a single error. Alarm start time: second 8; alarm end time second
23.
Channel 3: the error starts second 12 while the channel is monitored and ends second 20 when the channel is no
longer monitored. The monitoring unit detects the absence of error when starting to monitor the channel again.
Alarm start time: second 14; alarm end time: second 25.
It is also important to note that when a channel is not monitored, no measurements can be compiled on that specific
channel, leaving blanks in the recorded measurement curves.
As a rule, be aware that the higher the number of monitored channels, the lesser monitoring time is spent on each.

4 5 6
1- Update the information entered when the channel was created as needed.
Select the monitoring mode:
• Active monitoring: the unit monitors, logs measurements and generates alarms on out of tolerance
conditions
• Measure without alarm: the unit monitors and logs measurements
• Standby: the channel is configured but not monitored.
For alarms to be generated, the option “Send alarm” needs also to be enabled at the parameter level.
Modify the monitoring cycle duration if needed: when a single receiver monitors multiple channels, this is the
time it will lock on this channel for monitoring before moving on to the next.
2- RF level monitoring:
• Check parameters you want to monitor and the alarms you want to send
• display additional options , explained chapter 4:
o Time out before alarm
o Hysteresis
o Intermittent error max number allowed in the time window
o Intermittent error threshold

Alarm threshold(s)
Levels can be adjusted in the text box or graphically by clicking and dragging the alarm threshold line.
On the graphic, the line turns red when your mouse is on the right place to grab it.
If the values are out of range, the text zone is framed in red.
All levels are relative to the reference. To update the reference to the current value, press the button ‘Update
Reference’.
3- MPX level, MPX Power, Pilot level and stereo presence, Audio level, RDS level and presence, Aux level:
• Check parameters and options as for the RF level
• In the RDS levels section, manage the RDS error rate monitoring: enter the appearance and
disappearance error rate as well as the frame analysis.
4- RDS identification:
• Check parameters you want to monitor and the alarms you
want to send
o PI: indicate the reference PI code(s)
o PS: indicate the code” type (static or scrolling) and the
reference PS code(s)
With a static code, the PS must include exactly 8 characters. When
automatically retrieved, the Audemat FM Probe adds spaces to
complete the string if it is shorter. When entered manually, add
spaces if needed.
o TA
o PTY: indicate the reference PTY and the trigger type
(PTY changed or specific PTY)
o AID: indicate the reference AID code
o Update references as needed
5- RDS parameters:
• Check parameters you want to monitor and the alarms you
want to send
o AF list (method A): give the list of alternative
frequencies
o RDS clock: indicate the time offset threshold, and
notification triggers.
o RDS groups: check applicable groups
o EON TA
o EON TA PI: indicate the reference
o Update references as needed
6- Watermarking:
• Check parameters you want to monitor and the alarms you want to send
• For monitoring watermark changes, indicate the reference ID (integer)

6.5. Managing channels
On the Manage channels page, detect broadcasted channels or configure them manually to be able to monitor them.
1
Launch the RF band scan to automatically detect channels.
Use the standard scan or the fast scan:
• The standard scan is run on a single input
• Available when signal is present on the 3 physical receivers and the Audemat FM Probe is in multi-tuner
mode (see section 6.8.1). In this mode the scan is run simultaneously on all available inputs.
The standard band scan always runs on receiver 1. This action interrupts all others of that receiver (monitoring and
real time).
Once the band has been scanned, channels can be added to the monitoring list.

Edit channel information (name and frequency) in the monitoring list.
Remove a channel from the monitoring list; all associated data (readings, alarms) is then deleted.
Monitored channels are immediately added to the left menu.
The number of receivers varies between 1 and 8 depending on purchased options. See section 1.2.1 for more
details.
Stations selected to be monitored must be assigned to any available receiver according to your needs:
The more stations are assigned to a given receiver, the less time will be spent to
monitor each stations. You may want to distribute stations across available
receivers.
As an alternative, you may use manually configure a channel (3): click on “Create
Manual Channel”, enter its name, select the receiver, enter its frequency and
click the Create button.
A manually configured channel is directly added to the monitoring list.
The audio output is available for any monitored station. Simply click and drag the desired station to enable the rear
panel analog outputs (4). The audio output level can be adjusted directly on the web interface.

Many times, all channels should be set in the same way. This is what the channel configuration template helps with:
you will create a template file from an existing properly configured channel and select it to apply it to new channels
(4):
• Select one channel to be monitored
• Navigate to the channel settings page and configure the channel
• Go back to the Channel management page and click the Configuration Helpers button
• Select the channel you just set as reference channel and give a name to the new template
• Download the template. The .dat template file will be saved in your download directory
• Upload the template you just created
• All channels created after the new template has been applied will
have the same configuration as your reference channel.
The name of the current template is displayed on the channel management
page and can be directly modified by clicking the pen icon.
Any value can be edited in the window and saved directly in the unit template.
The previously downloaded file will not be affected by these changes.
Downloaded templates may be used on other units.
