The Rohde & Schwarz FSH-K44E option offers code domain power measurements for in-depth WCDMA / HSDPA / HSPA + analyzes. This enables the channel performance of occupied and unused code channels to be displayed graphically. The resulting summary provides an overview of the most important signal parameters such as RF channel power, code channel power and composite EVM. The code domain channel list contains additional information such as symbol rate, channel number with associated spreading factor and automatic detection and display of the associated channel type.
