5.8.1 Free Vote & Fade Hold Times
Free Vote is a vote settling period. During this time, voting activity has no effect on the transmitter
steering decision.
The Free Vote time is the interval between the detection of initial receiver activity and the triggering of a
TSAM action. This time determines how long the TSAM will wait after detecting receiver activity before
it recognizes this activity as an input requiring action.
Free Vote allows the comparator to settle before the TSAM makes any transmitter steering decisions.
Once the Free Vote time has expired, the TSAM will start the steering process using one of the steering
criteria outlined in section 2.1.
Free Vote time is programmable from 0 to 32.767 seconds in 1 ms increments. It can normally be set at
the default of 50 ms. Some systems, particularly those using hybrid analog/digital voting may require a
larger time, up to approximately 250 ms.
Fade Hold
The Fade Hold time is the interval between the end of receiver activity and the triggering of an End of
Reception event. Fade Hold prevents the TSAM from executing End of Reception events on short signal
dropouts. If receiver activity resumes before the Fade Hold time expires, no End of Reception event
occurs. This keeps the TSAM from resteering on short signal dropouts.
