Execute this command to enter the downlink/uplink channel or uplink multicode time
offset TFrame value.
TFrame in Downlink Mode
TFrame adjusts the number of timeslots that the channel 1 radio frame is offset from the
Perch radio frame and long code phase zero. Total offset is equal to TFrame plus TSlot. For
additional information, see“Understanding Time Offsets”on page3-8.
Range:
0 to15 timeslots
Status after *RST: 0 slots
TFrame in Uplink Mode
TFrame adjusts the number of timeslots channels 1, 2 and 3 radio frames are offset from
long code phase 1280. Total offset is equal to TFrame plus TSlot. For additional
information, see“Understanding Time Offsets”on page3-8.
Range:
0 to15 timeslots
Status after *RST: 0 slots
Transmission Direction, Uplink or Downlink
[:SOURce]:RADio:WCDMa[:BBG]:CCHannel DLINK|ULINK
[:SOURce]:RADio:WCDMa[:BBG]:CCHannel?
Execute this command to toggle the transmission direction between downlink and uplink.
When the signal generator is in the uplink mode, it must be frequency-locked to the base
station receiver using the uplink trigger feature. Refer to“System Configuration”on
page3-16 and“Rear-Panel Overview”on page3-11 for additional information.
Choices:
