TV Configuration
Selecting TV from the left menu, will open the TV parameters configuration screen:
LNB L.O.
is set to 0 by default. It should be set to the desired value if it is necessary to
down-convert the signal frequency into the TV band (VHF or UHF) before starting the
measurements.
C/N TYPE
by default is set to
OUT BAND
and can be also set to
IN BAND
. If is set to mode
IN BAND
the signal/noise ratio is measured between the signal level of the video carrier and
the noise level, estimated in the band between the colored subcarrier and the audio carrier;
if set to
OUT BAND
mode the signal/noise ratio is measured between the signal level of the
video carrier and the noise level estimated in the guard band (-1.250 MHz from the video
carrier
).
DISCOVERY
could be set to both
TERRESTRIAL ONLY
or to
TERR&CABLE.
If set to
Terrestrial Only
, it means that the Auto discovery function will look only for terrestrial (DVB-
T / T2); when set to
Terr&Cable
, the Auto discovery function will look also for DVB-C
channels.
FIELD STRENGHT
is set to
OFF
by default. It should be configured when the meter is used
to perform field measurement campaigns using an external antenna. This parameter can be
set to
OMNIANT
,
LOGANT
(which are the factory default ones – corresponding to the
recommended antennas) but also to
CUSTOM
meaning that the user can define a new
antenna type.
To each antenna type corresponds an
antenna factor table
that will be applied during the
measurement campaign to determine the correct field strength value.
EDIT ANT.FACTOR
is enabled only if
Field Strength
is set to
CUSTOM
. It displays a table
containing 10 calibration points, each identified by the frequency, the Antenna factor value
and the cable loss, as shown in the next page:
