[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:SYNC:MODE SINGle|CONTinuous
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:SYNC:MODE?
This command selects the synchronization triggering mode. The following choices are
available:
SINGle Once triggered, the ESG generates one set of frames based on the
reference clock.
CONTinuous The sync signal and frame timing are continuously aligned.
*RST: Single

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:SYNC[:SOURce]?
This command selects the uplink synchronization source type. The following choices are
available:
SFN_RST System frame number reset signal
FCLock Frame clock signal
*RST: FCLock

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TOFFset?
This command sets the timing offset in chips between the downlink signal and the uplink
signal. A minus value means a negative delay. The actual timing offset is (T0) + (Timeslot
Delay) + (Timing Offset) where T0 (= 1024 chips) is the standard timing offset between
downlink and uplink.
Range:
−
512 to 2560 chips
*RST: 0
