W-CDMA/HSPA+ Demodulator Menu
CDP: Open the CDP Menu. When Code Domain Power (CDP) is selected the screen displays all the selected OVSF codes and selected OVSF zoom codes in the graphical format. The display also displays P‑CPICH Abs power, EVM, Carrier Frequency, Channel Power, Carrier Feedthrough, Frequency Error in Hz and PPM, Noise Floor and Peak CD Error. The screen also displays control channel view with CPICH, P‑CCPCH, S‑CCPCH, PICH, P‑SCH and S‑SCH powers in the table format. If the marker is set on the code, the marker will display the code number, power and Symbol EVM.
Note: For the W-CDMA/HSPA+ demodulator option, the CDP screen displays HSPA+ and W-CDMA signals. P‑CPICH Abs power, EVM, Carrier Frequency, Channel Power, Carrier Feedthrough, Frequency Error in Hz and PPM, Noise Floor and Peak CD Error are also displayed. The screen displays CPICH, P‑CCPCH, S‑CCPCH, PICH, P‑SCH and S‑SCH powers in the table format. If the marker is set on the code, the marker will display the code number, power and Symbol EVM.
CDP Table: Displays the following Code Domain Power (CDP) parameters in table format: Code, Status, EVM, Mod Type, Power (dB), and Power (dBm).
HSPA+: Open the HSDPA Menu. When HSPA+ is selected the screen displays all the selected OVSF including high speed data channel codes and selected OVSF with high speed codes in the graphical format. The selected code Power versus time and Constellation diagram will be displayed. The display also displays control channel view with P‑CPICH Abs power, EVM, Carrier Frequency, Channel Power, Carrier Feedthrough, Frequency Error in Hz and PPM, Noise Floor and Peak CD Error. The screen also displays CPICH, P‑CCPCH, S‑CCPCH, PICH, P‑SCH and S‑SCH powers in the table format.
Note: This screen is available with the W-CDMA/HSPA+ demod option only.
Codogram: Open the Codogram Menu. When Codogram is selected the screen displays the changes in code power levels over time. Two graphs are displayed on the screen, the top one displays all the selected OVSF codes and the bottom one displays the selected OVSF zoom codes.
Modulation Summary: Displays the demodulation parameters in the table format.
Back: Returns to the Measurements Menu.
