E-DPDCH Configuration Summary Table
This section defines the Settings Current and Apply Needed buttons. Only one button is available at any time. These buttons are available in all of the W-CDMA/HSPA+ Uplink's tree nodes.
|
|
This button indicates that the current real-time settings have been applied to the instrument. No action is required. |
|
|
This button indicates that the instrument settings are not current and need to be updated to be applied to the instrument. Click this button to update the instrument's settings. [:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:APPLy [:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:APPLy? |

Power (Main)
Range: –40 to 0 dB
Default: 0 dB
Set the E-DPDCH power in dB. This power is assigned to each E-DPDCH when multiple E-DPDCHs are configured. The entered power is typically set to the channels as SF4. Where the E-DPDCHs are configured to SF2x2 + SF4x2, the channel power of SF2 is 3.01 dB higher than the entered power.
