DPCCH 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.

When loading a user file through the software's Data dialog box, the MXG/EXG requires an ASCII text file consisting of 1s and 0s. When using SCPI commands, all instruments require a binary data file.

Custom Pattern

Sets the E-DPCCH data pattern to Custom Pattern. The value of this command is a string which is represented ‘0’ or ‘1’. The maximum data length is 10 patterns.

User File

This variable specifies a data pattern that has been stored in memory.

If the parameter set by the following command is changed while the signal is active, the :ULINk:APPLy command or Apply Needed () button must be executed for the change to occur.
