SMCIP 401 ASI

ener al
As signal source four Tuners (or instead of Tuner D the ASI input signal) are
available.
The status menu informs whether the tuners A…D are "locked"/"not locked" to
an input signal, if stations are selected in the menu Station selection:
DVB-S =>
A–cD
DVB-S
V 8
In this example …
… no station from tuner B is selected (indication "–"),
… stations from tuners A and D are selected and have reception (capitals),
… a station from tuner C is selected but reception is disturbed (lower case).
—> If the ASI input is selected instead of tuner D, its state is displayed
accordingly.
The output signal (new transponder) can be fit in a gap of a SAT IF range.
Therefore the corresponding range must be connected to the LNB input. At the
RF output the SAT IF range with fit in "new" transponder is present.
—> To ensure that an existing gap will not occupied by the satellite op-
erator, you can cut the upper end of the frequency spectrum in order
to generate your own gap by using a filter to the LNB input
9
. Our
filters lower the frequency spectrum from 1920 MHz ("GF1920")
resp. 2120 MHz ("GF2120") on to -30 dB.
