CALL[:CELL]:TIMing:EXTernal:OFFSet
|
Function
|
Sets/queries the External 8960 Synchronization Offset.
This parameter is intended for use with the "Synchronize External 8960 Offset" action. This offset parameter will be provided to the external 8960 along with the SFN & chip of the reference trigger. The external 8960 will add the offset to the trigger time to determine the new starting SFN and chip for the timing chain. This starting time will take effect the moment the next trigger arrives.

Setting
|
Two integer values in the range: 0 to 4095, 0 to 38399

CALL[:CELL]:TIMing:EXTernal:MEASurement?
|
Function
|
Queries the External 8960 Timing Measurement result.
This result is displayed on the Main node when Multi-Cell UTRAN mode is enabled successfully, or following the "Synchronize External 8960 Offset" event. It is defined as the number of frames and chips by which the external 8960s PCCPCH timing, leads the local 8960 and can be determined from the following equations.
Frames = ((((SFN_ext * 38400) + Chips_ext) - ((SFN_loc * 38400) + Chips_loc)) / 38400) % 4096Chips = ((((SFN_ext * 38400) + Chips_ext) - ((SFN_loc * 38400) + Chips_loc)) % 38400

CALL[:CELL]:TIMing:EXTernal:SYNChronize
|
Function
|
Synchronizes the External 8960 Offset. This immediate action controls the relative time alignment of two test sets. It requires that an external connection be present between the two test sets.
