TSector in Downlink Mode
TSector adjusts the Perch radio frame timing and long code relative to the BTS reference
System Frame Number Reset output at the DATA OUT rear-panel connector. This is
accomplished by adjusting the offset (in number of chips) from the falling edge of the
System Frame Number Reset to the first symbol of the Perch radio frame and long code
phase zero, measured at the RF output. For additional information, see“Understanding
Time Offsets”on page3-8.
Range:
0 to2560 chips
Status after *RST: 0 chips
TSector in Uplink Mode
TSector adjusts channels 1, 2 and 3 radio frame timing and long code phase relative to the
BTS reference System Frame Number Reset input at the PATTERN TRIG IN rear-panel
connector. This is accomplished by adjusting the offset (in number of chips) from the falling
edge of the System Frame Number input to the long code phase 1280 of channels 1, 2 and 3
measured at the RF output. Total offset is equal to uplink trigger delay (propagation delay)
plus TSector. For additional information, see“Understanding Time Offsets”on page3-8.
Range:
0 to2560 chips
Status after *RST: 0 chips

Execute this command to enter the downlink/uplink channel or uplink multicode time
offset TSlot value.
TSlot in Downlink Mode
TSlot adjusts the number of symbols channel 1 radio frame is offset from the Perch radio
frame and long code phase zero. Total offset is equal to TSlot plus TFrame. For additional
information, see“Understanding Time Offsets”on page3-8.
Range: seeTable5-6
