The independent AoIP audio streaming provision is discussed
separately on Page 33.
‘VU’ Meter
As explained earlier, SOFIA 568 metering is peak-responding.
The Web interface display follows the 10-segment front-panel
LED bar readout; see Page 13 for additional details. Metering
with higher resolution is displayed on the
Graphs & Metering
Web interface page and are covered under that discussion.
Signal Metrics
Directly below the prominent frequency notation near the top
of the page, you’ll find a cluster of off-air signal quality
readouts.
With the exception of
Pilot
and
HD
, which
only indicate an unlocked, a syncing or a
locked condition, each of the other six qual-
ity notations is accompanied by a scrolling
30-second graphical history of the associat-
ed readout, plus low and high values for
the same period.
Here’s a synopsis of the parameters shown:
RSSI
is received
signal carrier strength in dBuV;
RF SNR
is a generalized sig-
nal/noise figure for the off-air signal;
HD Level
is a relative level
measurement of the HD Radio carrier pair;
CD/No
and
DQ
are
relative quality assessments of the decoded HD Radio digital in-
formation based on error statistics,
CD/No
best representing HD
Radio reception quality;
Multipath
is a relative measurement of
multipath (direct/reflected) distortion effects. The signal quali-
ty measurements will prove useful when setting-up a receive
antenna.
Pilot
and
HD
simply indicate
Locked
or
No Lock
.
Alarms
The SOFIA 568 offers alarm indications for various signal-
related issues. Alarm status is displayed on the front panel, be-
low the signal metrics readout here on the
Now Playing
Webpage, and on the Alarms Webpage where the alarm trigger
and reset parameters are set. Alarm specifics and setup proce-
dures begin on Page 25.
In addition to the alarm status indicators, the individual alarms
can be assigned to rear-panel GPO terminals to tie into remote
control systems, light accessory indicators, or trigger a siren,
etc. GPO programming is explained on Page 31.
Alarms can also send email or SMS/text messages to specific
personnel. This is detailed beginning on Page 35.
Audio Program
Metadata
The SOFIA 568 displays metadata associated with the audio
program being monitored.
When analog FM is selected as the source, the RDS (Radio Data
System)
PI-Call:
(PI code and call letters), the static or scrolling
PS:
(Program Service) field and
RT:
(RadioText) messaging is
shown.
When listening to HD Radio transmissions, the readout will in-
stead display PAD (Program Associated Data) information; the
