Operating Manual 1176.7610.02 ─ 02

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 command:

Find Sync On/Off ← Find Sync ← Output Power

Activates or deactivates the search of the sync word. The default setting is activated.

The results of the modulation measurements Modulation Characteristics, Initial Carrier
Frequency Tolerance, Carrier Frequency Drift can only be calculated if the softkey is
activated. The measurement of the Output Power can be performed with either this
softkey or the Find Burst On/Off softkey activated. If both softkeys are activated, the
search area for the sync word will be limited to the area of the detected burst. If the
Find Burst On/Off softkey is not activated or no burst is identified, the total record
length (search length) is investigated.

Remote command:

Sync Offset ← Find Sync ← Output Power

Defines the number of bits to be displayed in front of the of the first preamble bit p

0

. 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.

Remote command:

Find Burst On/Off (Output Power) ← Find Sync ← 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.
