Applications

3GPP FDD code domain power measurements

The R&S®FSH-K4 option allows code domain power measurements on a 3GPP base station. It measures the total power and the power of the most important code channels, such as the common pilot channel (CPICH), primary common control physical channel (P-CCPCH), primary synchronization channel (P-SCH), and secondary synchronization channel (S-SCH). Furthermore, the carrier frequency offset and the error vector magnitude (EVM) are measured and displayed. The scrambling code can be determined at the press of a button and used automatically for decoding the code channels. The user can also get a quick overview of adjacent base stations. The R&S®FSH can display up to eight scrambling codes with their CPICH power. The R&S®FSH-K4 option provides automatic level setting for fast and optimal setting of the reference level. In practice, this means very easy operation. To display the code domain power measurement values, only four operating steps are necessary:

  • Select the 3GPP CDP function
  • Set the center frequency
  • Use “Level Adjust“ to optimize the level setting
  • Start the scrambling code search

For base stations with two antennas, the user can select which antenna the R&S®FSH should synchronize to (antenna diversity).
