‘VU’ Meter
SOFIA 567 audio level metering
is peak-responding, and the
Web interface level display at
the top of each Web interface page follows the 10-segment
front-panel LED bar readout. Metering with greater resolution
can be found on the
Graphs & Metering
Web interface page and
is discussed and qualified in detail on Page 18.
Signal Metrics
and Alarms
Directly beneath the
prominent frequency
notation near the top
of the page, you’ll
find off-air signal
quality readouts and
alarm indicators.
The two signal quality notations are accompanied by a scrolling
30-second graphical history, plus low and high values over the
time period shown.
RSSI
is received signal carrier strength in dBuV at the antenna
input.
RF SNR
is a generalized signal/noise figure for the off-
air RF signal, not an audio SNR measurement. These metrics
are useful when setting-up the receive antenna.
Alarms
The SOFIA 567 offers alarm indications for three signal-related
issues. Alarm status is displayed on the front panel, in this ar-
ea of the
Now Playing
Webpage, and on the
Alarms
Webpage
where the alarm trigger and reset parameters are set. Alarm
specifics and setup procedures begin on Page 21.
In addition to the alarm status indicators, the individual alarms
can be assigned to rear-panel GPO terminals to tie into remote
control systems or to light an LED at the operating position.
GPO programming is explained on Page 25.
Alarms can also send email or SMS/text messages to specific
personnel. Instructions for setting this up begin on Page 29.
Tuning
the Radio
The SOFIA 567 is easily tuned from the front panel Tuner menu,
or from the
Tuner
section of the
Now Playing
Webpage. Using
the Web interface you can either directly overtype an FM fre-
quency into the box to the right of
Frequency (kHz):
, or you can
grab the slider knob and drag it back and forth. Or click on the
slider knob and, once it’s highlighted, use your keyboard arrow
keys to move up and down the dial. The
< >
arrows on the
screen also allow incremental tuning.
Station Presets
You may enter as many as 30
station-memory
Preset Stations
.
Preset memories hold not only
the tuner settings, but the in-
dependent alarm settings for
each individual station as well.
