Double-click or use the drop-down menu to enable or disable the bursting in the waveform. When enabled, the packet transmission timing of the test signal adheres to the
Bluetooth TDD slot structure for the selected packet type.

At the beginning and end of a packet transmission, the signal source ramps power following a user-defined burst profile. The burst profile is defined by setting the Power Ramp and Ramp Settling fields with the desired time duration (in microseconds) (see figure below). The ramp profile is the duration of time prior to the first symbol transmission, over which the carrier frequency is ramped from idle power to transmit power. The power ramp is shaped with a cosine function, and length of the ramp can be adjusted. The Ramp Settling field sets the length of time allowed for the power level to stabilize prior to the first symbol transmission of the first bit of the preamble.
