nel, something we found
extremely helpful in our
test. The meter performed
flawlessly when prompted
to read a user-defined fre-
quency or even the entire
reception range, if required.
All channels that are found
are saved onto the channel
list fully automatically.
In order to make sure a
signal tilt caused by ampli-
fiers, distributors or long
cables etc. does not distort
a measurement result the
WS-6936 offers the option
to select several frequen-
cies at once and creating a
side-by-side presentation
of their parameters (signal
level and signal quality). On
a single screen it is possible
to show up to five channels
at the same time. Using the
arrows keys it is possible
to switch between screens.
This way a signal tilt can be
recognised reliably and then
eliminated.
As always, we created a
number of scenarios for our
practical test, starting with
aligning a 90cm antenna to-
wards TURKSAT 42° East,
then setting up a DiSEqC
motorised dish and finally
aligning a UHF antenna for
optimum DVB-T reception.
We began with entering
the coordinates of our lo-
cation and selecting TURK-
SAT as our target satellite.
Thanks to the spectrum dis-
play and the azimuth and el-
evation values provided by
the WS-6936 it was child’s
play to correctly position
our antenna. The ultimate
fine-tuning was achieved
with the help of the sig-
nal level and signal quality
bars, so that our first job
was completed in next to no
time.
In most cases, the align-
ment of a motorised anten-
na requires a meter plus a
satellite receiver with DiS-
EqC 1.2 and 1.3 compatibil-
ity. This has changed with
the arrival of the WS-6936:
Thanks to a wise decision by
Baotong both functions are
packed into a single prod-
uct. This takes the scare
out of installing motorised
antennas and in our test we
only took a little over half an
hour to arrive at a perfectly
aligned motorised antenna
for reception of all positions
between 75° East and 30°
West, at least as far as the
measurement results indi-
cated by the WS-6936 are
concerned.
But then again, are those
results 100% trustworthy or
does the manufacturer give
out glossed over results?
We performed the same
test with a much more ex-
pensive professional meter
and as you can see in the
screenshots, we arrived at
almost the same values. So
the WS-6936 actually did a
brilliant job.
Please note, however,
that while the WS-6936
does say that one of the
signal quality values indi-
cates C/N, this value is ac-
