The following table describes the IRD’s behavior for each of the acquisition modes and the
defined timeouts (see SETTIMEOUT terminal command):

Table 9.  Acquisition Mode Behavior

Acquisition Mode

Description

Tracking

In Tracking Mode, the unit tracks (monitors) an acquired carrier.  This
is the only mode in which the unit can provide video, audio, and/or aux
data.  The unit will move to the Header Search mode if, (1) an invalid
network header is detected in the COMPEL network stream, or (2) the
time since the last valid network header was detected exceeds the NO
COMPEL Timeout (#4 in SETTIMEOUT command).

Fade

The purpose for this mode is to reacquire a 

faded

 carrier (caused by

rain, sun-outs, etc).  The unit allows the receiver daughter-card to
automatically re-acquire the carrier on its own using a restricted search
algorithm.  This mode is vacated for the Installation mode after the
Fade Timeout (#1 in SETTIMEOUT command).

Installation

While in this mode, the unit continually performs an installation type
acquisition on the requested carrier.  Installation type acquisitions cover
a ~+/-2 MHz range, and should occur in under 30 seconds.  This mode
is generally used at power up and for all user-requested acquisitions.
This mode is vacated for the Carrier Search mode after the Installation
Timeout (#2 in the SETTIMEOUT command).

Carrier Search

While in this mode, the IRD resorts to the Settings Table for finding a
carrier.  The IRD continually moves down the table performing one
complete installation-type acquisition on each valid entry in the table,
including the last acquired and last requested entries.  Each individual
search last one minute.  After the last entry is searched, the unit repeats
the search from the top of the table.  This mode is vacated only if a
carrier is successfully acquired, OR if a local user issues a tuning
command.  However, after expiration of the Carrier Search Timeout
(#3 in the SETTIMEOUT command), if Local Control had been
previously disabled, then it is re-enabled.

Header Search

Identical to carrier search, except that the unit is looking for a carrier
with valid COMPEL network headers present.  If a carrier is
encountered, the unit will wait the amount of time given by the Header
Seek Timout (#5 in the SETTIMOUT command) before moving on to
try other carriers in the Settings Table. This mode is vacated only if a
carrier is successfully acquired 

and

 a valid header is received, OR if a

local user issues a tuning command.  However, after expiration of the
Header Search Timeout (#6 in the SETTIMEOUT command), if Local
Control had been previously disabled, then it is re-enabled.
