Table 1: Example of Trickle Power Mode Control.
Note:
If the receiver is set into the Trickle Power Mode, the high data rate

Computation of Duty Cycle and On Time
The Duty Cycle is the desired time, which will be spent for tracking. The
On Time is the duration of each tracking period (range is 200 - 900 msec.)
To calculate the Trickle Power update rate as a function of Duty Cycle and
On Time, use the following formula:
On Time – (Duty Cycle * On Time)
Off Time = ---------------------------------------------
Update rate = Off Time + On Time
Hint:
It is not possible to enter an On Time > 900 msec.
