TSector
Press this softkey to enter the downlink/uplink channel or uplink
multicode time offset TSector value.
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 page 3-8.
TSector in Uplink Mode
TSector adjusts the channel 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 page 3-8.
