• Min. Level: indicates the level from which the
meter must take the echoes into account.. You can
also change this level by dragging the horizontal
light blue level.
• Zoom: OFF, 2x, 4x, 8x, 16x. You can also Spread/
pinch on the screen.
• Units: us, Km.
• Restart Att: restarts the control attenuation.
• Quality profile: allows to select the quality profile
• Powering:
- VDC: Selects the preamplifier powering.
- DiSEqC (only satellite band): selects the
DiSEqC parameter (Sat A, Sat B, Sat C, Sat
D)
- Positioner (only satellite band): makes it
possible to control the DiSEqC motors
used to move mobile parabolic antennas.
This function is available in satellite mode
and when the equipment is powering the
LNB.
Halt: This command stops the motor
movement.
East: Allows to move the motor in the
EAST direction. Each click corresponds to
one step in the movement of the motor
(pitch motors). By holding the key down,
successive movement sequences will be
executed until the key is released.
West: Motor movement in the WEST
direction. Each click corresponds to
one step in the movement of the motor
(pitch motors). By holding the key down,
successive movement sequences will be
executed until the key is released.
Store: 8 storage positions are available
to store at up to 8 antenna positions . This
command allows one of 8 positions to be
chosen where the current position of the
antenna will be stored.
Goto: recovers one of the 8 positions
for the antenna that has been previously
stored
- SCR (only satellite band): Selects the SCR
parameters (multiswitch, standard and
slots) When a slot is enabled (for example
slot 3, freq. 1210MHz), the meter will tune
into the slot frequency (1210MHz) and
will set the slot with the meter parameters:
frequency, band (powering), and DiSEqC.
In addition, a SCR icon will be shown in the
bar at the top (SCR3) to indicate that the
slot is enabled. While the slot is enabled,
all the setting changes of the meter, will
be applied to the currently slot (SCR3).
6.4.8.- MER/carrier (RF Input)
This feature represents MER value for each carrier
of the ATSC3.0 signal. This is pretty useful to detect
if there is any interference inside the channel that
makes the quality signal to get worse and that is
invisible for a traditional spectral analysis.
6.4.8.1.- Main window
• MER RMS: Average MER.
• MER max: Maximum MER value of the signal.
In parentheses the number of carrier with
this maximum value of MER. If you tap on this
measurement, the blue mark will move to the
carrier with the maximum MER, and will be moving
searching the carrier with maximum MER each
time.
• MER min: Minimum MER value of the signal.
In parentheses the number of carrier with
this minimum value of MER. If you tap on this
measurement, the blue mark will move to the
List of measurements of the
selected channel
Tap on it to see the parameters
The blue mark indicates the
MER of the carrier where
the mark is placed
The light blue mark
indicates the average
MER of the carriers
Average, maximum
and minimum MER
