Introduction
EN 50607 specifies the second generation of channel stacking systems for satellite reception. The second
generation allows more reception possibilities by increasing the number of user bands and the number of
satellite feeds.
This Technical Report provides implementation examples to assist manufacturers and installers of satellite
distribution and satellite receiving equipment to implement EN 50607 in the most convenient way and to
ease installation of products according to EN 50607.
1 Scope

here. In particular, Universal and Wideband LNB architectures for different SHF bands (Ku-, Ka- and
C-Band) are taken into account.

The following examples show block diagrams for one user band only. For more user bands, switch matrix
and converter blocks can be multiplied accordingly.
Function blocks are simplified (no pre-selection filters etc.).
Data format is simplified (offset of 100 MHz in transmitted data is ignored).
Only analogue converters are shown, the examples can be adapted for dCSS solutions accordingly.
Basically, the examples describe applications with:
a) Universal LNB (see 4.2);
b) Multi-switch with feed by Quatro LNB (see 4.3);
c) LNB´s with wideband architecture (see 4.4.);
d) Multi-switch with wideband feed see (4.5);
e) Two satellite reception (see 4.6);
f) C-Band LNB´s (see 4.7);
g) Universal Ka Band LNB with dual wideband hardware (see 4.8);
h) Multi-switch with feed by LNB (dual wideband feed) in 4.9;

Figure 1 — SCD2 Universal- LNB — Example for Ku Band
This example shows a typical Universal LNB with a bank switch and one channel-stacking converter. The
bank switch is controlled using the SCD2 bits .0 (“band”) and .1 (“polarity”). The oscillator of the CSS
converter is controlled by requested IF frequency from receiver plus frequency of the user band. In the
receiver, the LOFs are set accordingly to the real LOFs of the LNB.
EXAMPLE Receiver is set to UB1 with 1 280 MHz. Desired program is 11 494 MHz, low band, horizontal. Receiver
is configured to LOF 9 750 MHz for low band. Receiver calculates IF = 11 494 MHz – 9 750 MHz = 1 744 MHz. This
information is sent in SCD2 data format. To convert 1 744 MHz to 1 280 MHz, the SCD2 converter sets the oscillator to
Fo = 3 024 MHz.
NOTE Concerning LNB configuration (entering of LO frequencies for Low band and High band in), the necessary
configuration measures by the installer are the same as for legacy DiSEqC LNBs. The procedure described above of
course is also valid for LNBs operating in other frequency bands (for example Ka Band). An application with a Universal
LNB which covers a frequency range of more than 2,05 GHz (dual wideband hardware) is described in 4.8.

Figure 2 — SCD2 Multi-switch with standard feed by Universal LNB — Example for Ku Band
This example shows a typical application of a CSS multi-switch with a standard L-Band signal provided by a
Quatro LNB. The bank switch of the CSS converter is controlled using the SCD2 bits .0 (“band”) and .1
(“polarity”). The oscillator of the CSS converter is controlled by requested IF frequency from receiver plus
frequency of the user band. In the receiver, the LOFs are set accordingly to the real LOFs of the LNB.

Figure 3 — SCD2 LNB with wideband architecture — Example for Ku Band
SCD2 also supports CSS LNBs using wideband architecture. In the above example, only one LOF with F =
10 400 MHz is used. Functionality of a Universal LNB with standard band architecture is emulated; therefore,
the receiver does not need special settings. The polarity switch is controlled using the SCD2 bit .1
(“polarity”). A band switch is emulated by adding an offset to the frequency of the CSS conversion oscillator.
The offset depends on the SCD2 bit .0 (“band”) and is - 650 MHz for low band and + 200 MHz for high band.
SCD2 Universal Wide-Band LNBs using other LO frequencies than 10 400 MHz can be realised by using
other offset frequencies (e.g. - 450 MHz and + 400 MHz for LOF = 10 200 MHz).
EXAMPLE 1 Receiver is set to UB1 with 1 280 MHz. Desired program is at 11 494 MHz, low band, horizontal.
Receiver is configured to LOF 9 750 MHz for low band. Receiver calculates IF = 11 494 MHz – 9 750 MHz = 1 744 MHz.
This information is sent in SCD2 data format. In the SCD2 converter, low band request is received, so with this wide-
band LNB hardware, the desired program can be found 650 MHz lower than with standard Universal LNB hardware. To
convert the required channel 1 744 MHz to 1 280 MHz, the SCD2 converter sets oscillator to Fo = 1 744 MHz –
650 MHz + 1 280 MHz = 2 374 MHz.
EXAMPLE 2 Receiver is set to UB1 with 1 280 MHz. Desired program is at 11 836 MHz, high band, horizontal.
Receiver is configured to LOF 10 600 MHz for high band. Receiver calculates IF = 11 836 MHz – 10 600 MHz =
1 236 MHz. This information is sent in SCD2 data format. In the SCD2 converter, high band request is received, so with
this wide-band hardware, the desired program can be found 200 MHz higher than with standard L-Band hardware. To
convert the required channel 1 236 MHz to 1 280 MHz, the SCD2 converter sets oscillator to Fo = 1 236 MHz +
200 MHz + 1 280 MHz = 2 716 MHz.
NOTE Because Universal LNB emulation is used, the necessary configuration measures (entering LO frequencies
in the STB menu) are equivalent to the NOTE in 4.2.
