Custom Digital Modulation (Option 431)
Using Customized Burst Shape Curves
Burst shape maximum rise and fall time values are affected by the following factors:
• the symbol rate
• the modulation type
When the rise and fall delays equal 0, the burst shape is attempting to synchronize the maximum
burst shape power to the beginning of the first valid symbol and the ending of the last valid symbol
of the timeslot. The following figure illustrates a bursted signal in an EDGE frame with a rise delay
of 0 and a fall delay of +1 bit.
