R&S FSL 3GPP Base Station Measurements (Option K72)
1300.2519.12 4.277 E-11
Scrambling Code
Opens an edit dialog box to enter the scrambling code. The scrambling codes are used to
distinguish between different base stations. Each base station has its own scrambling code. The
scrambling code range in hexadecimal format is [0x0 … 0x5FFF]
The scrambling codes are divided into 512 sets, each consisting of a primary scrambling code
and 15 secondary scrambling codes.
The range of the primary scrambling codes is described by n=16*i
with k=0, i
[0 ... 511] = [0 ... 1FF].
The range of the secondary scrambling codes is described by j=16*i+k,
with k
[1 ... 15] = [1 ... F].
Example:
To enter the primary scrambling code number '1', the digits '10' need to be entered. (i = 1, k = 0).
The entered scrambling code has to coincide with that of the signal. Otherwise, a code domain
power measurement of the signal is not possible.

Scrambling Code Autosearch
Searches automatically the scrambling code that leads to the highest signal power and stores it
as new scrambling code for further measurements. All scrambling codes of the recorded signal
are taken into account. As a prerequisite, the center frequency and level settings have to be
correct.
The scrambling code search automatically determines the primary scrambling code number. The
secondary scrambling code number is expected to be 0. Other scrambling codes can not be
detected. Therefore, the range for detection is 0x0000
– 0x1FF0h, where the last digit is always
0.
Remote: CDP:LCOD:SEAR
Show List
Displays a result list of the automatic search sequence containing the highest power values
calculated and the corresponding scrambling codes. The power shown is a coarse value for the
CPICH power.
This softkey is only available after a scrambling code auto search has been performed (see
Scrambling Code Autosearch softkey).
Remote: CDP:LCOD:SEAR:LIST?
Format Hex/Dec
Selects the display format of the scrambling codes:
Hex
hexadecimal
Dec
decimal
The default setting is hexadecimal.
