This function can provide a visual reference of the signal level of the vertical and
horizontal polarisations at a frequency. This can be used to adjust the LNB skew for
maximum isolation. Many satellite transponders (like Astra 28.2 for most frequencies)
operate so that the vertical and horizontal polarisation signals are not usually at the same
frequency, but others (like Hotbird) have some transponders that operate with vertical
and horizontal polarisations at the same frequency. To ensure that you use a “good”
transponder for this isolation test, use the Spectrum Analyzer to check the signals.

This function starts the beeper with a frequency depending on the current SNR reading.
As the SNR increases, so does the frequency of the tone.

This function allows checking of all transponders for some satellites. The satellites that
are testable with this function are Astra 28.2E, Astra 23.5E, Astra 19E, Hotbird 13E, Sirius
4.8E, and Thor 0.8W. When the function is started, the satellite to be tested is shown on
the screen. Turning the knob selects a different satellite to be tested. Pressing the
button starts the test. Each transponder on the satellite is checked and if locked, then an
upward vertical line is shown. With the Satlook HD, if the transponder is DVB-S2, then
the vertical line is shown slightly longer. On the Satlook G2, this transponder will fail to
lock. If the transponder cannot be locked after three tries, then the vertical line is
downward. At the completion of the test, the knob can be used to review any missing
transponders and show the frequency and polarity for further checking using the
Spectrum or Digital modes. Although all transponders for a satellite are tested, failure to
lock may occur for several reasons. This is an accelerated test designed to run quickly
and it is possible that the demodulator may not lock in the short time allowed, or the
transponder may not have a broadcast “footprint” that covers your area.
