14. Switching from SaTCR
(SCR - Single Cable Routing)
and DiSEqC. In SCR mode
the individual frequency win-
dows of the antenna jacks can
flexibly be edited so that the
S7000 can be harmonized with
practically every SCR switch.
15. In DiSEqC mode DiSEqC
1.0 and 1.1 multiswitches can
be controlled (for up to 4 or
16 LNB inputs) as well as a
DiSEqC 1.2 positioner. Simple
tone-burst switches can also
be controlled.
16. The Sat Finder function
shows the active satellite‘s
selected transponder signal
level. If needed, an audio tone
can also be turned on so the
antenna can be aligned wit-
hout having to look at the ana-
lyzer. The arrow buttons can
be used to switch satellites
without having to leave the
current display screen.
The specialty of this feature
is the automatic calculation
of azimuth, elevation and LNB
skew. This data is obtainable
thanks to the GPS antenna;
the current position is of
course also shown. If for some
reason the current geographi-
cal position can‘t be obtained
from the GPS, this information
can also be entered manually.
At first this might not seem
all that critical; the antennas
are always mounted outdoors.
But what if the installer wants
to pre-align the antenna in
his workshop so that he can
install it more quickly at the
customer? Then it could be
very practical to enter the
customer‘s position in ahead
of time.
17, 18, 19. The S7000 can
reception parameters like
symbolrate, FEC and modu-
lation. Many instruments fail
at this seemingly simple task
and therefore need current
and specially setup channel
lists. Not true with the Devi-
ser S7000: it recognizes these
parameters on its own and in a
very short time. Sure enough,
markers can be used to select
a desired transponder (or the
frequency can be directly
entered) and in measurement
mode the S7000 determines a
variety of reception parame-
ters in 1-3 seconds and also
simultaneously shows these
20, 21, 22, 23, 24. Naturally, the
S7000 can also play audio and
video and includes the corre-
sponding decoders for analog
and digital signals in MPEG2
and MPEG4. This mode can
be accessed at any time with
the TV button. If the signal
has not yet been locked on
to, because perhaps in spect-
rum mode the marker was just
placed on top of a transpon-
der, the analyzer determines
the corresponding reception
parameters on its own, just
like in measurement mode.
In just a few seconds the live
picture of an unencrypted
channel is displayed and you
can quickly switch between
channels via the transponder
service list. The S7000 shines
with channel switching times
of 1-3 seconds depending on
the type of signal and modu-
25. In this mode the Deviser
S7000 even has a complete
transponder stream analy-
zer available. This function is
geared more towards techni-
cians that are responsible for
head-end stations, transmis-
sion or reception systems. All
analyzer functions are availa-
ble for each received trans-
ponder stream regardless if
they originate from the inter-
nal DVB-S/S2, DVB-C, DVB-
T/H tuners, from the ASI input
or, for example, from an exter-
nal transponder stream file.
The first picture shows the
transponder stream‘s primary
data. The bandwidth is shown
as well as NIT information and
the stream‘s basic statistical
26. In the second picture,
EVENT INFO, additional infor-
mation on the quality of the
transport stream is shown.
27. The third screen, PID
VIEW, shows the assignment
of the different PIDs. This data
is also important for installers
because it can provide impor-
tant error conclusions with
the setup of smaller head-end
stations and IPTV servers, for
example, if the wrong PIDs
were accidentally configured.
28. The fourth screen, PROG
GRAPH, displays details on
the selected channel within
These parameters provide
important information on the
resolution and, above all, the
CODECs in use. If a custo-
mer complains, for example,
that a specific channel can‘t
be played back by a receiver,
then the reason could be that
the channel is encoded with
professional equipment using
4:2:2 Chroma, instead of the
standard receiver based 4:2:0
