SATELLITE DISH POINTING (SAT POINT function)
As this is a function which is used often and is, at the same time, facilitated by our automated high-resolution spectrum, we
thought we would dedicate a chapter to this subject (please also refer to the “QPSK” SPECTRUM).
a) Activate SAT mode, analog or QPSK (whichever you prefer).
or simply select a SAT programme, preferably in centre band, already pre–stored to receive the satellite and relative
band and polarization you require (e.g. Hot bird 13° E, VE l HI ↑, 11842,0 MHz).
b) Press SPECTRUM.
c) Press ENTER (to quit MRK FREQ)
d) Press the key twice to go to MODE.
e) Press , and press once or twice to go to
f) Connect the LNB assembled on the dish to the RF IN of your meter.
g) At this point the SAT POINT function has already automatically set the best SAT spectrum vision for you to carry out
satellite dish pointing, without having to touch your meter again (see fig.1).
h) Start pointing your dish (whose elevation has already been adjusted) in the correct direction until you can see some
carriers appear out of the noise and maximise them as shown in the two examples below (fig. 2 and 3). In theory the
satellite dish pointing is now complete; later we will see how to make it perfect and/or simplify the procedure using
some of the instruments special functions.
