R&S FSL Bluetooth Measurements (Option K8)
1300.2519.12 4.169 E-11
LAP
Opens an edit dialog box to enter the lower 24 bit (Lower Address Part, LAP)of the Bluetooth
Device Address (BD_ADDR) of the equipment under test (EUT).
The LAP is used to calculate the 64–bit sync word. The sync word in return is used to determine
the start of a packet by correlation and to determine the position of the first preamble bit p0
using the method described in the RF Test Specification.
The values for the lower address part range from 000000h to FFFFFFh. The default setting is
0000000h.
Remote: DDEM:SEAR:SYNC:LAP #HA3F45B
Sync Offset
Opens an edit dialog box to define the number of bits to be displayed in front of the of the first
preamble bit p0. If the sync word is identified, but the selected measurement time cannot be
displayed due to the selected sync offset, the message SYNC OFFSET INVALID is displayed.
The value range depends on the search length and the upper limit of symbols (400001 points /
symbol). The default setting for the sync offset is 0.
This softkey is only available if the Find Sync On/Off softkey is activated.

Find Burst On/Off (Output Power)
Activates the burst search if the Find Sync On/Off softkey is deactivated. Beside the
synchronization on the sync word, the Output Power measurement can perform a burst search
to evaluate the signal according to the standard.
If the Find Sync On/Off softkey is not activated and no burst is identified, the message BURST
NOT FOUND is displayed, and the corresponding bit in the STATus:QUEStionable:SYNC
register is set during remote operation.
