3.1 Pointing and Peaking Tones
The Pro Portable incorporates a Point-and-Peak process that uses digital tones for acquiring a satellite’s signal. These
tones assist a user in identifying the peak azimuth and elevation angles to maximize connectivity (Table 3-1).
Table 3-1: Pointing and Peaking Tone List
Tone Name Description Audio Example
Heartbeat
The Heartbeat tone indicates the TRIA is receiving power from the modem,
but is not pointed at a satellite it recognizes. This tone is the initial tone at
the beginning of the Point-and-Peak process. It is only heard when the
TRIA pointed outside of the frequency range of a Beam.
Ring-Ring The Ring-Ring tone defines the “edge” of the Satellite Beam and sounds
like an old style telephone. The tone is only heard when entering the
Beam. Therefore, to find both the right and left edges of the Beam, the
Installer will sweep to the left, then sweep back to the right. This allows
the modem to learn all the frequencies available in the beam.
Single Short
Beep The Single Short Beep tone is a ‘confirmation’ that the alignment process
has found the correct satellite. This tone occurs just after Ring-Ring tone
defines the edge of the Satellite Beam.
The Single Short Beep is always heard in combination with the Ring-Ring.
Low/Slow and
High/Fast The Low/Slow and High/Fast tones are a set of tones that grade the
frequencies being learned by the modem. This allows the Installer to
hear/identify the center and the edges of the Beam.
High/Steady The High/Steady tone indicates the center of the currently known
frequency set. To find the correct center, the user must complete the
entire Point-and-Peak process. When the final Center Point Frequency is
found, the antenna will pass.
Beep-Bop The Beep-Bop tone indicates two modem states:

When the TRIA locates a satellite with Ka-Band frequencies that the
modem does not recognize

When the modem has reset during a re-Pointing process.
