R&S FSH
Code Domain Power Measurement on 3GPP FDD Signals
1145.5973.12 4.151
E-14
If the scrambling code is not known, the R&S FSH can automatically determine the scrambling code of
one or more 3GPP base stations. Two different modes are available for this purpose. In the Single
mode, the scrambling code of the base station with the highest signal level is determined. In the
Multiple mode, the R&S FSH can determine the scrambling codes of up to eight 3GPP base stations
together with the CPICH power. The automatic scrambling-code search assumes that the value of the
secondary scrambling code is 0.
Automatic scrambling code search in the Single mode:
Press the SCRAMB CODE softkey.
Using the rotary knob or the cursor keys, select
AUTO DETECT SINGLE from the menu
To confirm, press the ENTER key or the SCRAMB
CODE softkey.
The scrambling code search takes about 22 s. The
progress is indicated as a percent figure on the
display. As soon as it has found a scrambling code,
the R&S FSH synchronizes to the 3GPP signal of the
base station. The screen will show SYNC OK, and the
result values will be displayed.
Automatic scrambling code search in the Multiple mode:
Press the SCRAMB CODE softkey.
Using the rotary knob or the cursor keys, select
AUTO DETECT MULTIPLE.
To confirm, press the ENTER key or the SCRAMB
CODE softkey.
The scrambling code search takes about 50 s. The
progress is indicated as a percent figure on the
display. As soon as it has found the scrambling codes,
the R&S FSH synchronizes to the 3GPP signal with
the highest level. The screen will show SYNC OK, and
the result values will be displayed.
Displaying all scrambling codes found:
Press the VIEW SCR CODES softkey.
The R&S FSH will show all found scrambling codes
together the CPICH power.
To close the list, confirm with the ENTER key or the
VIEW SCR CODES softkey.
