Calculating a long multiple packet sequence
If a PN15, Continuous PN15, or a User File is chosen as the data pattern, a calculation
warning will appear. See Figure 11. The amount of time it takes your PC to calculate
the signal depends on the PC’s amount of RAM and the speed of the processor. As the
amount of samples shown in the Projected Length field increases, so does the amount
of time it takes the PC to calculate the signal. If the calculation takes longer than
20 minutes, it is likely that it has failed, even if an error message is not visible.

Control packets
As indicated in Table 2, the ID, NULL, and POLL packets do not contain a payload field. As
a result, the payload setup menu is disabled when one of these packet types is selected in
the packet type pull-down menu.
NULL and POLL packets are composed of an access code and header field (126-bit fixed
length). When configuring NULL and POLL packets, only the BD ADDR and AM ADDR
need to be set.
The ID packet is comprised of only an access code (68-bit fixed length). Because the
ID packet does not contain header and payload fields, only the BD ADDR needs to
be configured.
Bursting
In Packet Generator mode, bursting can be enabled or disabled in the Signal
Configuration menu, Figure 12.
Figure 12. Disable Bursting or set the Power Ramp and Settling times.
When enabled, the packet transmission timing of the test signal adheres to the
Bluetooth TDD slot structure for the selected packet type. A summary of the
transmission rates for each the packet types supported by the software is provided
in Figure 13.
