3.3.1.2.5 RF Signal Strength Factors

This screen defines how the L-Band power detector (RF) inputs is used. See sections x and for
references to the use of signal strength inputs.

LOCK:0 TIME:0.1 CONFIG-RF

TYPE <0-NONE 1-1HI 2-1LO 3-2HI 4-2LO>

LOCK:

<0-NONE 1-1HI 2-1LO 3-2HI 4-2LO>

When the autopeak source is the RF input, this item defines whether a discrete signal lock input is
required to indicate a satellite has been found. The signal lock input may help in distinguishing the
correct satellite while doing a LOCATE.

If a signal lock input is used, it may be defined as either having a HI (>3.5 VDC) or LO (< 0.8 VDC) level
that indicates lock.

TIME:

DELAY TIME <0.1 – 9.9> SECONDS

This item defines how long the RC4000 will wait after each step before sampling signal strength.
Increasing this value may be required to allow equipment such as a modem to generate an AGC output.

NOTE: if a RF_LOCK value of 0 (no signal lock conditioning) is selected, the RF_TIME item is ignored
and a smooth (non-stepping) scan will be implemented.
